The application of a selection of decision-making techniques by employees in a transport work environment in conjunction with their perceived decision-making success and practice : original researchAuthor Theuns F.J.

A lack of optimum selection and application of decision-making techniques, in conjunction with suitable decision-making practice and perception of employees in a transport work environment demands attention to improve overall performance. Although multiple decision-making techniques exist, five prevalent techniques were considered in this article, namely the Kepner-Tregoe, Delphi, stepladder, nominal group and brainstorming techniques. A descriptive research design was followed, using an empirical survey which was conducted among 210 workers employed in a transport work environment and studying in the field of transport management. The purpose was to establish to what extent the five decision-making techniques are used in their work environment and furthermore how the decision-making practice of using gut-feel and/or a step-by-step decision-making process and their perception of their decision-making success relate. The research confirmed that the use of decision-making techniques is correlated to perceived decision-making success. Furthermore, the Kepner-Tregoe, stepladder, Delphi and brainstorming techniques are associated with a step-by-step decision-making process. No significant association was confirmed between the use of gut-feel and decision-making techniques. Brainstorming was found to be the technique most frequently used by transport employees; however, it has limitations as a comprehensive decision-making technique. Employees working in a transport work environment need training in order to select and use the four comprehensive decision-making techniques.

This article sought to facilitate the optimisation of key performance measures utilised for demand management in air cargo operations. The focus was on the Revenue Management team at Virgin Atlantic Cargo and a fuzzy group decision-making method was used. Utilising intelligent fuzzy multi-criteria methods, the authors generated a ranking order of ten key outcome-based performance indicators for Virgin Atlantic air cargo Revenue Management. The result of this industry-driven study showed that for Air Cargo Revenue Management, 'Network Optimisation' represents a critical outcome-based performance indicator. This collaborative study contributes to existing logistics management literature, especially in the area of Revenue Management, and it seeks to enhance Revenue Management practice. It also provides a platform for Air Cargo operators seeking to improve reliability values for their key performance indicators as a means of enhancing operational monitoring power.

For many years the South African government has put forward policies and strategies to improve and promote public transport. Despite this, very little has changed over the last 30 years, although projects such as the Gautrain high-speed rail service and a few bus rapid transit routes have been introduced recently. These projects, however, are not integrated in a logical manner into the broader public transport system and are often referred to as standalone interventions because of a lack of managing public transport in terms of integrated transport plans. The traditional commuter rail, bus and 16-seat taxi industries therefore operate in policy silos and, in the case of the bus and rail industries, are planned and funded independently of each other, leading to a further lack of integration. Policy interventions have been implemented partially or not at all, leaving the public transport sector in a state of flux. The methodology followed in researching this paper was to briefly trace the historical public transport policy developments, with a focus on the commuter bus industry, in order to identify possible impediments to policy implementation and to identify policy interventions for addressing the currently stalled policy implementation programme. The main finding of the paper is that it would be advisable to establish provincial transport authorities between local and provincial governments. That should speed up the development and implementation of integrated transport plans, which ought to lead to integrated public transport systems and a more optimal spend of the available governmental funds aimed at subsidising public transport.
Exploring public bus service quality in South Africa : a structural equation modelling approach : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –10 (2014) http://dx.doi.org/http://dx/doi.org/10.4102/jtscm.v8i1.127More Less
This study, which is a deviation from the usual practice of using SERVQUAL or an adapted version thereof, uses McKnight, Pagano and Paaswell's (1986) service quality dimensions, namely reliability; extent of service; comfort; safety; and affordability (RECSA) and structural equation modelling to determine commuters' perception of public bus service quality in a major city in South Africa. The RECSA model was adapted and fitted to the data collected from a convenience sample of bus commuters in Johannesburg, using structural equation modelling. It was ascertained that reliability, service, comfort and safety influenced the public bus commuters' perception of the overall service quality. The implications of the aforementioned findings for providers of public bus services are explained.
Dynamics of intermodal logistical systems on containerisation and road transportation in Durban, South Africa : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –10 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.150More Less
The underlying port operations in Durban, South Africa, epitomise intense global competitiveness in the intermodal logistics chain. The link between containerisation and the road transport network can falter as a result of the dynamics of the logistics system. The main objective of the study was to establish the extent of the intermodal challenges of logistical systems on containerisation to which the role of intermodal sea-road freight transportation enhances the logistical competitiveness. It further examined the intermodal relationship on containerised freight between the challenges of containerisation processes and the effects on road freight transport mode. The impact of containerisation on intermodalism, the sea-road freight transport network and the technological attributes of security-based systems and logistical tracking protocols influence the systematic movement of containers on Durban's public roads.
Domestic airport passenger access mode choice decisions in a multi-airport region of South Africa : original researchAuthor Stephen CarstensSource: Journal of Transport and Supply Chain Management 8, pp 1 –7 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.149More Less
The ground access mode used by air passengers to an airport has a vital impact on infrastructural and environmental decisions. An important aspect of a passenger's mode choice is the sensitivity to factors such as access time and access cost. The objective of this research was to analyse air passenger's sensitivity to access mode choice attributes, that is, access time, access cost, parking time and parking cost at two airports in Johannesburg, South Africa. A stated choice experiment was used to obtain the information and a latent class model was estimated. In general, discrete choice experiments are designed to reveal respondent (preference) heterogeneity and the latent class model allows for this heterogeneity to be modelled discretely. The estimated results indicated that three latent classes provided the best fit with preference heterogeneity evident from the set of parameter estimates. The access mode used was found to be the only significant covariate in the class assignment model. The respondents' willingness to pay for a reduction in access time was estimated and it indicated that respondents had the highest access time willingness-to-pay value for the taxi as access mode. In addition, it was estimated that passengers being dropped off at the airport had a higher access time willingness-to-pay than passengers that used their own vehicles to the airport. The research results confirmed the presence of respondent heterogeneity (according to access mode) which resulted in different access time willingness-to-pay values.
The bus rapid transit system : a service quality dimension of commuter uptake in Cape Town, South Africa : original researchAuthor Prince D. UgoSource: Journal of Transport and Supply Chain Management 8, pp 1 –10 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.145More Less
This study evaluated commuter uptake of the bus rapid transit (BRT) system in Cape Town, South Africa. As a stated preference survey was not carried out prior to the launch of the new BRT system in the City of Cape Town, it became difficult to assess commuters' preferences, which would have provided City policymakers and planners with an understanding of customer satisfaction of the proposed bus service. The commuting trend of the BRT system in the City indicates that tickets sales and utilisation by commuters is gradually picking up, but one would have expected high commuter engagement in terms of the modernity profile of the BRT system. This study investigated commuters' (n = 260) satisfaction levels with 30 service quality variables on a self-rated questionnaire, using quantitative research methodology. The study result showed that passengers were not satisfied with the transport fare and the availability or accessibility of ticket sales outlets. In the context of this study, this result implies that the 'responsiveness and affordability' variable of the service quality dimensions should be an area of interest and review to City of Cape Town policymakers and planners. Service quality trends in public transport were also highlighted.

During the 20th century, freight transport in South Africa was employed to attain politico-economic ideals, resulting in the overprotection of rail and overregulation of road transport. Increasing industry pressure, combined with the international deregulation trend, led to deregulation in 1988. Myopia resulted in a rail investment hiatus and exponential growth in high-value, long-distance road transport, causing excessive logistics and externality costs for the country. The aim of this study was to propose a freight rail reform agenda based on, (1) lessons from past freight transport policy efforts and (2) the results of freight transport market segmentation driven by models developed over the past two decades. For the study, freight flows were modelled by disaggregating the national input-output model into 372 origin-destination pairs and 71 commodity groups, followed by distance decay gravity-modelling. Logistics costs were calculated by relating commodity-level freight flows to the costs of fulfilling associated logistical functions. The standard management approach of founding strategy development on market-driven segmentation provides a neutral input to steer rail reform discussions in South Africa. Market segmentation points to a dualistic rail reform agenda, enabling both a profit-driven core and a development-driven branch line network. Freight flow insights are steering the policy reform debate towards long-term freight strategy development and optimal freight logistics network design.
An investigation into the effectiveness of public entities' procurement practices : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –7 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.136More Less
The delivery of services through the procurement of goods and services requires proper strategic leadership and management processes. Inappropriate planning, under-spending of budgets and ineffective procurement form part of the root causes of poor service delivery, as this restricts the movement of resources to the right places. This study identified the leading procurement practices as: procurement strategy and leadership, the procurement process, human resource management, procurement information systems, supplier management and procurement performance management. These practices were then tested in public entities, mainly in Gauteng Province, South Africa, to determine the extent to which they are applied. The study found that there is a major divide between the perception of the level of application of the leading practices and actual implementation. Processes, skills, performance management, information technology (IT) systems and supplier management are applied inadequately or inappropriately. Most entities thus show a poor understanding of customer needs and there seems to be a general lack of customer focus. The study highlighted the best practice areas in which public entities are able to focus their efforts to better achieve excellent customer service and thus service delivery.
The alignment of product strategy to supply chain practices of craft businesses in Gauteng Province, South Africa : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –11 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.126More Less
External factors such as blurring market boundaries, escalating customer diversity and increasing global competitive threats have forced businesses to build strategies around key products and formulate market-driven strategies that are integrated with relationship and supply chain strategies to deliver superior customer value. Indeed, in the modern era of supply chain management, organisations are getting more integrated with their suppliers and customers as a way to manage the total supply chain. The purpose of this research was to determine if product strategies and supply chain practices of small craft business are aligned. Personal in-depth interviews were conducted with nine craft businesses operating in Gauteng Province, South Africa. The findings revealed that craft businesses struggle to match their product strategies with their supply chain strategies. Craft businesses also exhibited some inbound supply chain weaknesses.
Reducing risky driver behaviour through the implementation of a driver risk management system : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –10 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.146More Less
South Africa has one of the highest incidences of road accidents in the world. Most accidents are avoidable and are caused by driver behaviour and errors. The purpose of this article was to identify the riskiest driver behaviours in commercial fleets in South Africa, to determine the business impact of such behaviour, to establish a framework for the management of risky driver behaviour and to test the framework by applying a leading commercial driver behaviour management system as a case study. The case study comprised three South African commercial fleets. Using data from these fleets, critical incident triangles were used to determine the ratio data of risky driver behaviour to near-collisions and collisions. Based on managing the riskiest driver behaviours as causes of more serious incidents and accidents, the results indicated that through the implementation of an effective driver risk management system, risky incidents were significantly reduced.
Multi-stakeholder dialogue on formal and informal forms of public transport in Harare, Zimbabwe : convergence or divergence perspective : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –9 (2014) http://dx.doi.org/http://dx/doi.org/10.4102/jtscm.v8i1.140More Less
Cities in the developing world are growing both geographically and demographically. This growth has increased pressure on services, including the public transport systems used by the majority of people. In the last two decades public transport provision has undergone considerable changes. Concomitant to these changes there has been debate on the form of public transport to be operated. Such debate has been informal, general, and at times academic, and therefore not able to provide substantive understanding of the views of key stakeholders. Zimbabwe has had an explosion of informal transport activity in the form of minibuses, and decision makers appear to be in a policy dilemma because of a need to strike a balance between maximising passenger welfare whilst protecting the livelihoods of indigenous minibus operators and striving to build an efficient and environmentally sound urban transport system. Critical questions for policy dialogue in this conundrum include, inter alia: How do stakeholders perceive the current public transport system? How can public transport be sustainably provided? This study seeks to answer these questions using a case study of Harare. A qualitative research approach blended with some quantitative aspects was used. Initial steps involved the identification and clustering of key urban public passenger transport stakeholders, followed by structured and unstructured interviews. Although there is lack of consensus on the form of public transport that the City of Harare should adopt, there is a strong view that a mass transit system is the backbone of sustainable public transport.
Exploring the challenges associated with the greening of supply chains in the South African manganese and phosphate mining industry : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –9 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.139More Less
As with most mining activities, the mining of manganese and phosphate has serious consequences for the environment. Despite a largely adequate and progressive framework for environmental governance developed since 1994, few mines have integrated systems into their supply chain processes to minimise environmental risks and ensure the achievement of acceptable standards. Indeed, few mines have been able to implement green supply chain management (GrSCM). The purpose of this article was to explore challenges related to the implementation of GrSCM and to provide insight into how GrSCM can be implemented in the South African manganese and phosphate industry. This article reported findings of a qualitative study involving interviews with 12 participants from the manganese and phosphate industry in South Africa. Purposive sampling techniques were used. Emerging from the study were six themes, all of which were identified as key challenges in the implementation of GrSCM in the manganese and phosphate mining industry. From the findings, these challenges include the operationalisation of environmental issues, lack of collaboration and knowledge sharing, proper application of monitoring and control systems, lack of clear policy and legislative direction, the cost of implementing GrSCM practices, and the need for strong leadership and management of change. On the basis of the literature reviewed and empirical findings, conclusions were drawn and policy and management recommendations were accordingly made.

A country's competitiveness can be severely hampered by an uncompetitive freight logistics system. During the first decade of the 21st century, two in-depth models were developed for South Africa which provide a framework for measuring and improving the country's freight logistics system - the cost of logistics survey and the freight demand model. These models also allow for the development of scenarios for key identified risks. The objectives of this study were to provide an overview of South Africa's surface freight transport industry, identify key risks to national competitiveness and suggest ways in which these risks could be mitigated. Freight flows were modelled by disaggregating the national input-output model into 372 origin-destination pairs and 71 commodity groups, followed by distance-decay gravity-modelling. Logistics costs were calculated by relating commodity-level freight flows to the costs of fulfilling associated logistical functions. South Africa's economy is highly transport intensive. Excessive dependence on road freight transport exacerbates this situation. Furthermore, the road freight transport's key cost driver is fuel, driven in turn by the oil price. Scenario analysis indicated the risk posed by this rising and volatile input and should provide impetus for policy instruments to reduce transport intensity. As such, this study concluded that a reduction in freight transport intensity is required to reduce exposure to volatile international oil prices.
Developing Walvis Bay Port into a logistics gateway for southern Africa : issues, challenges and the potential implications for Namibia's future : original researchSource: Journal of Transport and Supply Chain Management 8, pp 1 –10 (2014) http://dx.doi.org/10.4102/jtscm.v8i1.154More Less
Many developing countries wish to become the 'gateway' to a region or part of a continent. One strategy involves encouraging logistics cluster development. These hubs support global supply chains and may enable the economic growth of the host country through the resulting trade, as well as providing direct and indirect employment opportunities during the build and subsequent operation of the hub. Namibia intends to develop the Port of Walvis Bay to become the preferred gateway to southern Africa and the Southern African Development Community region. This article builds on research on Caribbean cluster potential and Namibian logistics to identify the potential benefits and impact on development, as well as the drawbacks and risks of such a strategy.
