Passenger choice attributes in choosing a secondary airport : a study of passenger attributes in using Lanseria International Airport
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 Africa
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 manufacturers
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.
