Passenger choice attributes in choosing a secondary airport : a study of passenger attributes in using Lanseria International AirportSource: Journal of Transport and Supply Chain Management 10, pp 1 –10 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.256More Less
Background: The economic deregulation of the airline industry in South Africa in 1991 was a landmark event and brought about various changes in the air transport market, both locally and internationally. One important after-effect of deregulation was the entry of low-cost carriers (LCCs) in 2001, which increased competition in the market and offered passengers the freedom to choose between full-cost carriers and LCCs. It is generally accepted that LCCs have been very successful across the globe, and the main reason for this lies in their simplified lower cost business models. One way of achieving lower costs is for LCCs to operate from secondary or alternative airports. This trend is observed in most regions of the world. In South Africa, and more specifically the Gauteng province, Lanseria International Airport is considered as an alternative airport to OR Tambo International Airport (the main international airport of South Africa and located about 30 km east of the Johannesburg Central Business District [CBD]). Currently, two LCCs operate from this airport with a third LCC airline indicating that it will shortly begin operations from this airport.
Objectives: The research presented here reflects on the aspects passengers consider when selecting a secondary airport for their travel needs. It also compares the research findings of passenger attributes when choosing Lanseria Airport as a secondary airport in 2010 to a similar study in 2013 after another LCC commenced operations from the airport.
Method: In this exploratory research a face-to-face survey was used as the quantitative data collection method in order to identify the factors that influenced passengers’ airport choice decisions at Lanseria International Airport.
Results: From this research it emerged that when airports in a metropolitan area are close to one another, one of the main considerations for passengers is access time when selecting an airport. Even after a second LCC started operating from Lanseria International Airport, the attributes passengers regard as important in their decision to fly from the airport remained unchanged.
Conclusion: The aim of the research is to gain a deeper understanding of the factors involved in secondary airport selection and, building on this knowledge, to assist airport owners and managers in positioning their airports in a multi-airport competitive environment. Similarly, the findings of the research could assist airlines in their decision-making process to operate from secondary airports

Background: On a national level, South Africa’s freight logistics industry is inefficient. The country ranks 36th out of 40 countries in terms of transport productivity (tonne kilometres as a ratio of gross domestic product, or GDP); the ratio of freight logistics costs to GDP measured 11.1% in 2013, compared to that of developed regions which measures in the order of 9%; and rail tonne-km market share on the two most dense long-distance corridors, namely, Gauteng- Durban and Gauteng-Cape Town, is only 12.8% and 4.4%, respectively, whereas rail is globally acknowledged as a more efficient provider of long-distance freight solutions, given appropriate investments and service commitments.
Objectives: A cornerstone of improved national freight logistics performance is the availability of reliable indicators to quantify the efficiency and capacity of the logistics network over the intermediate and long term, thereby enabling an evidence-based policy and investment environment. The objective of this article is to describe the foundation framework (i.e. phase 1) for South Africa’s freight corridor performance measurement system (CPMS). Once populated, the CPMS will be a key generator of indicators to facilitate the systemic management of corridors as a national production factor and thereby contributing to South Africa’s competitiveness.
Method: The design of South Africa’s CPMS was informed by desktop research and refined through an extensive stakeholder consultation process. A distinction was made between South Africa’s dedicated bulk corridors and the multi-modal corridors.
Results: Facilitating both stakeholder involvement and agreement on key indicators, as well as the eventual development of a system supporting the population, aggregation and dissemination of the CPMS are critical outcomes for the management of corridors as a national production factor. Three overarching corridor indicators were defined, relating to increased throughput, lower costs and optimal modal application – the key rationale to improve the competitiveness of South African industry. This is supported by three corridor measurement perspectives, that is, a policy, customer service and infrastructure perspective. The purpose of the policy perspective is to support the role of national government in facilitating logistics competitiveness and equitable access through appropriate policy instruments. The customer service perspective should track service reliability and efficiency as contracted, at costs and cycle times that facilitate the competitiveness of the freight owner. The infrastructure perspective indicates whether sufficient capacity is provided, and whether this capacity is both available when required and utilised optimally.
Conclusion: Elevation of logistics to the macroeconomic realm through the development of appropriate indicators will enable the management of logistics as a national production factor, thereby contributing to reducing national freight logistics costs and improving industry competitiveness.

Background: Ports provide vital links in the maritime supply chains on which the trading of countries depend, and their efficiency and performance can contribute largely to the international competitiveness of those countries. However, to achieve and maintain such a contribution, port operators need to understand their role in a national economy and the factors that underlie the efficiency of the intermodal link that ports constitute in international supply chains. One such factor is the capacity of specialised cargo terminals.
Objectives: This article described a possible technique for forecasting the throughput of grain imports through the bulk grain terminal at the Port of Cape Town. It determined whether the capacity in the bulk grain terminal is sufficient to handle current and forecasted volumes of imported grains or whether the volumes justify expansion or upgrading of the bulk grain terminal in the Port of Cape Town.
Method: The Box–Jenkins methodology for autoregressive integrated moving average (ARIMA) models was applied. An ARIMA model – 2 parameter, 1 difference – was selected to do the forecast.
Results: The average tonnage of all grains imported through the Port of Cape Town that can be expected in a month is approximately 90 000 tons. The maximum tonnage of all grains imported through the Port of Cape Town that can be expected in a month is approximately 180 000 tons.
Conclusion: The analyses show that the demand for imports of grain products at the multipurpose terminal in the Port of Cape Town is not growing substantially. The analyses also identify that the current upper limits of grain imports are within the existing handling and storage capacities of the bulk grain terminal.
A green profitability framework to quantify the impact of green supply chain management in South AfricaSource: Journal of Transport and Supply Chain Management 10, pp 1 –15 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.251More Less
Background: The greenhouse gas emissions of South Africa are the largest contribution by a country in the African continent. If the carbon emissions are not reduced, they will continue to grow exponentially. South Africa’s emissions are placed in the top 20 in the world when considering per capita emissions.
Objectives: The aim of the research article was to investigate how the impact of implementing environmental initiatives on business profitability and sustainability can best be quantified in a South African business.
Method: Various methods, theories and best practices were researched to aid in the development of the green business profitability framework. This framework was applied to two case studies in different areas of the supply chain of a South African fast-moving consumer goods business.
Results: Results indicated that the green profitability framework can be used successfully to quantify both the environmental and profitability impact of green supply chain initiatives. The framework is therefore more suitable for the South African company than other existing frameworks in the literature because of its ability to quantify both profitability and sustainability in short- and long-term planning scenarios.
Conclusion: The results from the case studies indicated that the green business profitability framework enabled the tracking of environmental initiatives back to logistics operations and profitability, which makes it easier to understand and implement. The developed framework also helped to link the carbon emissions to source, and to translate green supply chain actions into goals.
Supply chain design approaches for supply chain resilience : aqualitative study of South African fastmoving consumer goods grocery manufacturersSource: Journal of Transport and Supply Chain Management 10, pp 1 –15 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.253More Less
Orientation: In today’s globalised and complex business environment, firms are ever more vulnerable to supply chain disruptions, originating both internally and externally from the supply chain. Supply chain resilience minimises the impact of a disruption through design approaches, which allows the supply chain to respond appropriately to disruptive events.
Research purpose: This article investigated the supply chain risks faced by grocery manufacturers in the South African fast-moving consumer goods (FMCG) industry and explored supply chain design approaches that enable supply chain resilience.
Motivation for the study: South African grocery manufacturers are faced with distinct risks. Whilst supply chain risk management studies have provided firms with certain guidelines to mitigate risk, supply chains are still vulnerable to unanticipated risks. Literature on supply chain resilience in the South African context is scant. The concept of supply chain resilience provides firms with strategies that are built into the supply chain that allow firms to react and recover swiftly from disruptions. Furthermore, supply chain resilience strategies assist firms in becoming less vulnerable to possible disruptions.
Research design approach and method: This study was conducted by using a descriptive qualitative research design. Data were collected through semi-structured interviews with senior supply chain practitioners specifically within the South African FMCG grocery manufacturing industry.
Main findings: The study found that labour unrest is the most common risk faced by the industry. Furthermore, strategic stock and supply chain mapping are of the most useful design approaches to enhance supply chain resilience.
Practical/managerial implications: The study provides managers with new insights in guiding supply chain design decisions for resilient supply chains. Through the identification of risks and appropriate solutions linked to the various risks, the study allows managers an array of options to choose from when enforcing a resilient supply chain.
Contribution/ value-add: The study contributes to the body of knowledge by being one of the first empirical studies conducted on supply chain design approaches for supply chain resilience in the South African context. The study also adds to the scarce literature on supply chain resilience in the FMCG industry, both globally and in a South African context.
Tuk-tuk, 'new kid on the block' in Johannesburg : operational and user travel characteristics, competition and impacts : original researchAuthor Tatenda C. MbaraSource: Journal of Transport and Supply Chain Management 10, pp 1 –9 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.214More Less
The three-wheeler tuk-tuk, popular in Asian cities is now a common feature in many cities worldwide, across all five continents. Their growth has been attributed to their distinctive flexibility, stylistic simplicity and modest operational costs. In Johannesburg, the tuk-tuk represents a relatively new mode of public transport which stemmed from suggestions made by the local area residents association and other stakeholders to revamp the neighbourhood. The objective of the paper is to determine the operational and user travel characteristics of tuk-tuks as well as assessing their impacts. In Johannesburg, where competition from private transport operators can result in serious confrontation, the paper ascertains whether tuk-tuks pose a threat to other operators. Data was collected through telephonic interviews and electronic questionnaires. The results reveal that the tuk-tuk has filled a public transport gap by providing a much needed 'first mile'/'last mile' service to community members.
The composite supply chain efficiency model : a case study of the Sishen-Saldanha supply chain : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –13 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.209More Less
As South Africa strives to be a major force in global markets, it is essential that South African supply chains achieve and maintain a competitive advantage. One approach to achieving this is to ensure that South African supply chains maximise their levels of efficiency. Consequently, the efficiency levels of South Africa's supply chains must be evaluated. The objective of this article is to propose a model that can assist South African industries in becoming internationally competitive by providing them with a tool for evaluating their levels of efficiency both as individual firms and as a component in an overall supply chain. The Composite Supply Chain Efficiency Model (CSCEM) was developed to measure supply chain efficiency across supply chains using variables identified as problem areas experienced by South African supply chains. The CSCEM is tested in this article using the Sishen-Saldanda iron ore supply chain as a case study. The results indicate that all three links or nodes along the Sishen-Saldanha iron ore supply chain performed well. The average efficiency of the rail leg was 97.34%, while the average efficiency of the mine and the port were 97% and 95.44%, respectively. The results also show that the CSCEM can be used by South African firms to measure their levels of supply chain efficiency. This article concludes with the benefits of the CSCEM.

The article seeks to explore the relationship between procurement in the public sector and corruption. Corruption in the procurement process is one of the biggest challenges facing the South Africa government. Procurement in the South African public sector through the tendering process has been used with a particular aim of addressing the past discriminatory practices and policies by empowering the previously disadvantaged majority. It ought to operate within a certain legislative and regulatory framework. However, the article argues that in the process of implementing the good intentions of the government, corruption illegitimises the process. There are also challenges that are associated with public sector procurement, with corruption being the main protagonist. The article also seeks to suggest possible solutions that could be used to address the anomalies. The article further concludes that the main reason for the rife corruption in the public sector is that there is non adherence to policy prescripts including the Public Finance Management Act, 1999 (Act 1 of 1999) and the Municipal Finance Management Act, 2003 (Act 56 of 2003). This enormous predicament may only be addressed if the government were to show will and commitment by punishing offenders who do not comply with the said legislative framework.
Supply chain integration : a qualitative exploration of perspectives from plastic manufacturers in Gauteng : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –13 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.223More Less
Background : Supply chain integration was identified as a tool to assist an organisation to survive in a competitive marketplace. It was unclear how plastic manufacturers in Gauteng perceived supply chain integration efforts between themselves and their suppliers.
Objectives : This study's main purpose was to investigate the nature and extent of supply chain integration between 10 plastic manufacturers in Gauteng and their suppliers. The focus was on these manufacturers' commitment to and perceptions of supplier integration efforts.
Method : The study was conducted with plastic manufacturing organisations in Gauteng, over a period of 2 months. A total of 10 participants were engaged through semi-structured interviews.
Results : The main findings of the study revealed that commitment and trust were found to be the antecedents of supplier integration and closer collaboration, while customer price pressure and limited available resources served as motivating factors for integration efforts.
Conclusion : It is recommended that organisations must revisit integration efforts when new markets are penetrated and top management support must be revisited using a strategic framework.

Background : Although conveyancing is a legal term, business management and specifically operations management principles also apply to the processes involved in conveyancing. From a business perspective, each organisation is usually concerned with its own profit margins and processes. In our global market, however, organisations now realise that they can no longer compete successfully on the basis of their internal operational efficiencies alone. They are therefore constantly aware of the need to improve not only their internal processes but also their alignment with other supply chain linkages in an effort to optimise the performance of the whole supply chain. Such alignment, in the conveyancing environment, includes government departments that are generally less willing to adopt business principles, which in turn makes optimisation of the whole supply chain more difficult.
Objectives : The article describes a supply chain perspective of the conveyancing processes in South Africa and reports some of the factors that influence and delay conveyancing transactions. It explores possibilities of collaborative relationships between different role players in the conveyancing supply chain. It aims to show that a supply chain approach, as opposed to a singular organisational approach, can help to reduce process bottlenecks and delays in order to improve overall process efficiency.
Method : The research, on which the findings are based, was exploratory in nature and followed a mixed-methods (quantitative or qualitative) approach and included both structured questionnaires and personal interviews.
Results : The results of the study revealed that many different types of delays occur at various entities across the whole supply chain involved in property transfers. These delays are presented in a table and diagram.
Conclusion : It is recommended that greater adoption of electronic technology across the whole supply chain would improve overall efficiency, eliminate bottlenecks and contribute towards efforts to optimise the conveyancing supply chain in South Africa. In addition, it is also recommended that the South African deeds registry implement an electronic system which would allow for the electronic lodging of property transfers.

Background : In this dynamic business environment, manufacturers are focusing primarily on delivery performance and competitive pricing to win orders. It is essential that manufacturers adopt flexible procurement systems (FPSs) in such an uncertain environment for business sustainability.
Objectives : The purpose of the study is to identify the elements of FPSs and model the interrelationships between elements of FPSs and, finally, to understand how FPSs are linked with supply chain sustainability.
Method : Besides providing a brief conceptual review of FPSs, the study largely illustrates the use of an innovative multi-criteria decision-making approach called total interpretive structural modelling (TISM).
Results : The total interpretive structural modelling-based model evaluates the causality and illustrates elements with interpretation of relations and suggests that bottom-level elements are vital for sustainability in FPSs and avert risks. Secondly, strategic sourcing is positively influencing supplier integration. Thirdly, supplier integration positively influences supplier responsiveness. Fourthly, skills of flexible procurement workforce positively influence supplier integration. Fifthly, it is found that supplier integration positively influences flexible transportation. The sixth finding suggests that supplier integration positively influences eco-friendly packaging. The seventh finding highlights that supplier integration positively influences ISO 14001 certifications. The eighth finding explains that supplier responsiveness positively influences customer satisfaction. It is also observed that flexible transport reduces operational cost and environmental costs. The second last finding explains eco-friendly packaging and reduction in environmental cost by careful selection of packing material and chemicals. Lastly, it is found that ISO 14001/environmental certifications reduce environmental costs by greening suppliers and pressurises them to follow environmental norms. This helps in reducing wastage and developing alternate raw materials, which are eco-friendly in nature. Environmental certifications of suppliers help in improving the image of the buyer firm in the business environment and attract more customers.
Conclusion : It is found that FPSs have a positive relationship with supply chain sustainability. In the end, the author highlights implications for supply chain practitioners and researchers.
Determinants of satisfaction with campus transportation services : implications for service quality : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –14 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.203More Less
Background : In a number of countries, buses are a critical element of public transportation, providing the most inclusive and sustainable mode of transportation to all forms of citizenry, including staff and students of universities.
Objectives : The study examines the determinants of satisfaction with campus bus transportation. The article is primarily discursive and based on the synthesis of existing service literature supported by data obtained from a survey of 847 respondents.
Method : Structural equation modelling is undertaken using AMOS 19, allowing for the examination of compound relationships between service engagement variables.
Results : Results show statistically significant differences between perceived service quality and travel routes. The authors argue that managerial attention to service user experiences does not only hold the key to ongoing competitive success in campus transportation services but also that those services can be significantly enriched through greater managerial attention to the interface between risk of financial loss (which increases when the campus bus transportation service provider becomes less able to compete) and service quality.
Conclusion : The authors argue that if providers of campus bus transportation services are to rise to their service delivery challenges and also maintain or improve upon their market positions, they must conceptualise their services in a manner that takes into consideration the two-way interrelationship between risk of financial loss and service quality. It must also be noted that, although this study may have relevance for firm-firm scenarios, its focus is primarily on service supplier firm-customer service engagements.
The latest 'big thing' for South African companies : enterprise and supplier development - proposing an implementation framework : original researchAuthor R.I. David PooeSource: Journal of Transport and Supply Chain Management 10, pp 1 –12 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.234More Less
Background : Although enterprise development and supplier development are two distinct concepts in the organisational and management literature, the Broad-based Black Economic Empowerment (B-BBEE) legislation refers to the enterprise development and supplier development as a single concept. As a result, many companies have a single policy, strategy and structural arrangements to manage enterprise development and supplier development programs and activities, thereby conflating the two concepts.
Objectives : The aim of this conceptual article was to propose an implementation framework for enterprise and supplier development and to show the rationale of keeping enterprise development and supplier development as two distinct but related activities.
Method : The conceptual article provided an overview of the policy context regarding enterprise development, followed by a discussion on enterprise development and its complexities. The article drew from the literature on supplier development and from the supplier adaptation, relational view, and learning and knowledge perspective theories in the development of its argument.
Results : The article presented an implementation framework for enterprise and supplier development and then concluded with some recommendations and direction for future research.
Conclusion : The implications of this research have great value for organisations as they prepare to implement Enterprise and supplier development (ESD) programmes. The proposed framework will also contribute to a better understanding of the ESD process and the link between enterprise development and supplier development processes.
Supply chain management best practices : a case of humanitarian aid in southern Africa : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –9 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.242More Less
Background : A key contemporary issue in the southern African region is the increased frequency of the number of natural disaster occurrences. Because of the extent of the damage as a result of these disasters, beneficiary needs have to be met to mitigate against consequent hardships and the loss of lives in the affected communities.
Objectives : This article reports on a study that investigated supply chain management best practices that are employed by the United Nations World Food Programme's (UNWFP) when dealing with disasters.
Method : This exploratory study consisted of five in-depth interviews with voluntary participants at the UNWFP regional office in Johannesburg to determine the various initiatives adopted by the UNWFP that ensure successful disaster relief operations. Thematic analyses were used to analyse the collected data.
Results : Based on the themes generated from the in-depth interviews, supply chain best practices were mainly linked to the concepts of agility, responsiveness and flexibility.
Conclusion : The main findings revealed that the strategic planning, implementation and controlling of agile, flexible and responsive supply chain practices can contribute to the success of logistical operations supporting humanitarian efforts in southern Africa.
Prioritising the implementation of practices to overcome operational barriers in reverse logistics : original researchAuthor Amanda BadenhorstSource: Journal of Transport and Supply Chain Management 10, pp 1 –12 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.240More Less
Background : Reverse logistics is a complex process, and many organisations experience operational barriers that prevent them from successfully managing the process. This study overcomes the gap in research regarding the most important practices that organisations can implement to overcome operational barriers in reverse logistics.
Objectives : The study aims to identify operational barriers preventing the efficient performance of the reverse logistics process, matching them to applicable practices by means of a theoretical framework and prioritising the implementation of appropriate practices with the inputs of practitioners.
Method : The study used a survey method, and data were collected by means of a questionnaire based on a theoretical framework that was sent to organisations that offered reverse logistics as a service or specialised in reverse logistics in South Africa. The study used descriptive statistics to conduct a gap-and-opportunity analysis.
Results : Respondents were asked to indicate the importance of the practices and how difficult they would be to implement. Results showed that all the practices are important to at least a moderate extent but some are more difficult to implement.
Conclusion : The framework developed in this article will enable organisations to identify the operational barriers they experience in reverse logistics and the practices they can implement on a priority basis to overcome these barriers.
Transportation decisions of small businesses in Soweto : balancing responsiveness and efficiency : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –11 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.238More Less
Background : The performance of small businesses makes an important contribution to the South African economy. Although the South African government implemented various initiatives for the development of small businesses in townships, the full advantage of such initiatives has not yet been experienced.
Objectives : To investigate how formal, independent small retail businesses operating in Soweto manage transportation as a logistical supply chain driver to be financially sustainable.
Method : During 2014, a survey was conducted among a sample of 556 formal, independent small retail businesses in Soweto to determine if these retailers focused on responsiveness or cost-efficiency when managing their logistical supply chain driver of transportation.
Results : The results showed that the retailers manage transportation decisions by focusing on either cost-efficiency or responsiveness, depending on the type of transportation decision and the industry in which the retailer operates. In terms of the profile of the older businesses (5 years and older) that showed a growth pattern in income (turnover) over the past year, responsive transportation decisions based on having inventory available (either by direct delivery by suppliers or by using own transportation) was a higher priority than considering cost.
Conclusion : The type of transportation decisions made by the older, growing businesses could serve as an example to younger businesses showing a stagnating or contracting growth pattern.

Background : South Africa has a disproportionately high freight transport demand owing to industrial development far from ports, low domestic beneficiation and improper modal use. Historical freight transport policy supported primary economic development, failing to preempt the changing economic structure and the resulting freight transport needs, resulting in excessive transport costs and externalities.
Objectives : To share the macroeconomic freight transport challenges revealed by South Africa's Logistics Barometer, and to identify key interventions to address these.
Method : Freight flows are modelled by disaggregating the national input-output model into 83 commodity groupings and 372 geographical areas, culminating in a 30-year forecast at 5-year intervals for three scenarios, followed by distance-decay gravity modelling to determine freight flows. Logistics costs are calculated by relating these flows to the costs of fulfilling associated logistic functions.
Results : Long-distance transport remains the largest general freight typology and is, due to inefficient macro logistics design, extremely costly, both in terms of intrinsic and extrinsic costs.
Conclusion : South Africa's freight task will grow 2.5-fold by 2043. Logistics and externality costs are already untenable at current levels. The development of domestic intermodal solutions will support the drive towards sustainable freight mobility.
Challenges faced by small-bus operators in participating in the formal public transport system : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –11 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.227More Less
Background : Small-bus operators (SBOs) in South Africa operate on the periphery of the economic mainstream of scheduled subsidised commuter transport, and little progress has been made in getting these operators into the more formal subsidised industry. There is also a lack of information about the challenges these operators face in participating in the public transport industry.
Objectives of the research : The main objective of the research was to conduct a survey among SBOs to obtain a better understanding of the challenges that they face in participating in the public transport industry.
Method : A telephone survey of operators was undertaken to ensure an adequate response to a structured questionnaire. In analysing the data, we made use of Factor Analysis and the Statistical Package for the Social Sciences (SPSS) to undertake general statistical analysis.
Results : The main results of the survey indicate that SBOs face significant financial and operational challenges. There is also a perceived lack of government support for SBOs. Major conclusions are that the Department of Transport (DoT) ought to address issues related to the complex governmental reporting and legal requirements for small business. In addition, government ought to be creating 'space' for SBOs in the design of contracts and actively encouraging the formation of consortia's or partnerships, among the SBOs and/or between SBOs and established bus companies. Government, and especially the DoT, ought to more actively market the governments' small-business support systems and procedures together with financial aid schemes to assist SBOs in acquiring or replacing buses.
Fuzzy VIKOR approach for selection of big data analyst in procurement management : original researchSource: Journal of Transport and Supply Chain Management 10, pp 1 –6 (2016) http://dx.doi.org/10.4102/jtscm.v10i1.230More Less
Background : Big data and predictive analysis have been hailed as the fourth paradigm of science. Big data and analytics are critical to the future of business sustainability. The demand for data scientists is increasing with the dynamic nature of businesses, thus making it indispensable to manage big data, derive meaningful results and interpret management decisions.
Objectives : The purpose of this study was to provide a brief conceptual review of big data and analytics and further illustrate the use of a multicriteria decision-making technique in selecting the right skilled candidate for big data and analytics in procurement management.
Method : It is important for firms to select and recruit the right data analyst, both in terms of skills sets and scope of analysis. The nature of such a problem is complex and multicriteria decision-making, which deals with both qualitative and quantitative factors. In the current study, an application of the Fuzzy VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR) method was used to solve the big data analyst selection problem.
Results : From this study, it was identified that Technical knowledge (C1), Intellectual curiosity (C4) and Business acumen (C5) are the strongest influential criteria and must be present in the candidate for the big data and analytics job.
Conclusion : Fuzzy VIKOR is the perfect technique in this kind of multiple criteria decision-making problematic scenario. This study will assist human resource managers and procurement managers in selecting the right workforce for big data analytics.
