Background: There is a logistical gap in the first section of the apple supply chain that affects the temperature profiles of apples further downstream in the supply chain.
Objectives: This article’s main objective is to confirm whether the logistics processes, in terms of the temperature profile of apples for the first 48 hours post-harvest, have an influence on the yield and/or quality of the fruit.
Method: Observations were made and informal interviews were conducted on three different farms to ascertain their perspective of the first section of the supply chain. Temperature trials were conducted to analyse the temperature profile of two apple varieties, namely Golden Delicious and Granny Smith on three different farms. These trials were conducted by placing an iButton® device on the inside and outside of an apple to measure the temperature readings every minute for the first 48 hours after picking.
Results: The research identified that it is not only at what time the apples are being harvested, but also at what time the apples are placed under cooling conditions to remove the field heat to obtain the recommended temperature profile within 48 hours. In addition, it was determined that effective and efficient picking at the right time (especially between 07:00 and 09:00) and the transportation of the apples directly, or as soon as possible after the apples came out of the orchard to the centralised cold storage facility, are key in ensuring the quality of the fruit and the temperature profile necessary for export.
Conclusion: This article identifies the need to improve operational procedures along the cold chain. From this research, it is clear that there are problem areas that affect the temperature profile of apples.
The correlation between relationship value and business expansion in the South African automotive supply chains
Background: The South African automotive industry includes complete supply chains. The South African automotive supply chain stakeholders operating within the global arena are faced with opportunities as well as challenges. The South African government supports the automotive industry and encourages the vision to drastically expand the industry by the year 2020. However, having to adhere to strict prescriptions from customers regarding product quality and logistics, automotive component suppliers have only the actual relationship with customers through which value can be added. Literature acknowledges the importance of relationship value and agrees that it results in business retention. However, literature fails to prove whether relationship value can result in business expansion where more business is generated.
Objectives: The objective of this article was to provide a better understanding of how to optimise relationship value within the South African automotive supply chains between Tier 1 and Tier 2 suppliers. Furthermore, the correlation between relationship value and business expansion was tested through a linear regression model. It was also important to determine whether supply chain stakeholders from different countries of origin and cultural backgrounds attach the same importance to relationship value.
Method: This article reports on research which followed a positivistic paradigm, through a quantitative study undertaken in the South African automotive supply chains. Members of the National Association for Automobile Component and Allied Manufacturers of South Africa (NAACAM), defined as Tier 1 suppliers, were approached to describe their best Tier 2 suppliers. Questions relating to relationship value and business expansion were asked via a closed-ended questionnaire. The aim was to obtain the perceptions of Tier 1 suppliers of their best Tier 2 suppliers in terms of relationship value and business expansion. The data were analysed through a linear regression model.
Results: It was found that relationship value directly correlates with business expansion and is therefore highly regarded as important by Tier 1 suppliers in terms of their Tier 2 suppliers in the South African automotive supply chains. Notwithstanding the different countries of origin, respondents are in agreement regarding the importance of relationship value.
Conclusion: As the South African automotive industry plays an important role in the South African economy, all efforts should be made to retain and expand the industry. The industry is characterised by a difficult economy, and supply chain role players should constantly investigate new strategies to gain a competitive advantage. It was found that there was a high regard for relationship value which could result in business expansion. Automotive component suppliers are encouraged to invest in a relationship value governance strategy to actively pursue added benefits for all stakeholders.
The impact of green supply chain management in small to medium enterprises: cross-sectional evidence
Background: South Africa has a high rate of small to medium enterprises (SMEs) failure, especially in the manufacturing sector. The operational challenges confronting manufacturing SMEs are acknowledged by the Global Competitiveness Index that ranked South African SMEs as one of the lowest in emerging economies.
Objectives: The aim of this study is to examine the association between green supply chain management (GSCM) practices, environmental collaboration and financial performance in SMEs.
Method: The study is quantitative in nature and involves a convenient sample of 312 SMEs based in Gauteng Province, South Africa. Data analyses follow a two-step process involving a confirmatory factor analysis to test the psychometric properties of the measurement scale and Structural Equation Modelling to test the proposed hypotheses.
Results: The study shows that three GSCM practices, namely, green procurement, green logistics and green manufacturing in SMEs exert a positive effect on environmental collaboration, with green manufacturing exerting a higher effect than the other two constructs. In turn, higher levels of environmental collaboration inspired higher levels of SME financial performance.
Conclusion: The study advances that SMEs can succeed financially through the influence of enhanced environmental collaboration, which emanates, in part, from the adoption and implementation of GSCM practices.
Background: The public sector occupies a key role in the economy comprising the appropriation of state revenue to purchase goods and to render services productively, while ensuring the optimum utilisation of available funds and resources to benefit the inhabitants of the country. Problems in the Zimbabwean public procurement sector that detract from service delivery are key contemporary issues. This is evident from the numerous complaints of poor service delivery received by the public that can be attributed to public procurement.
Objective: The purpose of this article was to report on a study that investigated problems in the different stages of the operational procurement process in the Zimbabwean public sector that detract from service delivery, the extent of these problems and how the public procurement process can be improved to enhance service delivery.
Method: This descriptive and exploratory study followed a quantitative approach. Data were collected by means of a questionnaire administered to all public entities in Zimbabwe. Data were analysed using SPSS.
Results: The majority of the identified problems in the public procurement sector that detract from service delivery are found in the advertising, bid evaluation and contract stages.
Conclusion: As only a few studies on this topic have been conducted in Zimbabwe, the findings of this research add a significant perspective to the existing body of knowledge and can assist stakeholders with regard to how the public procurement process can be improved in order to enhance service delivery through public procurement process reform and restructuring.
Background: Freight transport infrastructure is an indispensable requirement for economic growth, development and prosperity. Public–private partnerships (PPPs), as a mechanism to fund and construct freight transport infrastructure, have been suggested by many in private and public sectors.
Objectives: The concept of PPPs is dealt with, and the relevance of this mechanism is expanded upon. It is clear that PPPs in the rail environment present huge challenges and complexities. The objective was to determine whether PPPs are a viable mechanism to fund freight transport infrastructure in South Africa.
Method: Experiences with rail PPPs worldwide have shown that many failures occurred implementing these. The challenges and complexities of PPPs, in the freight rail environment, are highlighted together with the benefits, risks and best practices of PPPs. It is shown that suitable policies, legislation and regulations concerning PPPs are in place in South Africa.
Results: A proper framework and methodology to proceed should be in place. PPPs take time and are complex. Government involvement remains essential. Firm contractual agreements between parties are essential. Risk handling, risk sharing and the magnitude of risks should be clarified with agreement on where the risks reside. Financial viability, with value for money (VfM) and financial benefits for private sector role players are non-negotiable.
Conclusion: Appropriate legislation for implementing PPPs must be in place while two further important elements are economic circumstances and proper project execution. Taking all these factors into consideration, the freight transport sector can only benefit from successfully negotiated and implemented PPPs.
