- ItemIdentifying temperature breaks in the export cold chain of navel oranges : a Western Cape case(Elsevier, 2020-11) Goedhals-Gerber, Leila Louise; Khumalo, GculisileResearch shows that significant volumes of food produced globally is wasted due to supply chain failures from farm to retail. In addition, the category of fruits, vegetables, roots and tubers has the highest loss and wastage rate of any food per annum. Temperature has the greatest influence on fresh-produce deterioration rates and potential market life. Temperature breaks that occur in the cold chain result in financial losses due to quality loss issues and deviation from export protocols as well as a loss in market opportunity. This article presents a case study on navel oranges exported from Citrusdal in the Western Cape, South Africa to the United States of America. The United States of America is a steri-market, which means citrus fruits shipped to their ports must be exported at sub-zero temperatures for phytosanitary purposes. The procedure is known as cold sterilisation treatment. The likelihood of temperature breaks occurring in a vital industry in the economy prompted further investigation. The article aims to highlight the importance of the cold chain, from the citrus farms to the port of destination, by discussing trial shipments conducted on navel oranges. The results showed that temperature spikes and temperature breaks do occur along the navel orange export cold chain from the orchards until the navels are loaded onto reefer vessels. The results also showed that no temperature breaks are experienced once the navels are loaded on-board the reefer vessels. The research benefits the South African fruit industry by identifying the need for continuous improvement of the cold chain, which would assist in minimising temperature breaks.
- ItemThe measurement of supply chain efficiency : theoretical considerations and practical criteria(Stellenbosch : University of Stellenbosch, 2010-03) Goedhals-Gerber, Leila Louise; Pienaar, W. J.; University of Stellenbosch. Faculty of Economic and Management Sciences. Dept. of Logistics.ENGLISH SUMMARY: In an effort to compete globally, South African supply chains must achieve and maintain a competitive advantage. One way of achieving this is by ensuring that South African supply chains are as efficient as possible. Consequently, steps must be taken to evaluate the efficiency levels of South African supply chains. This dissertation develops the composite supply chain efficiency model using variables specifically identified as problem areas experienced by South African supply chains. The composite supply chain efficiency model evaluates the overall efficiency of a supply chain based on three criteria, namely, reliability efficiency, cost efficiency and speed efficiency. It identifies bottlenecks along the supply chain and in so doing identifies key focus areas for firms if they want to improve their overall efficiency and become more competitive. 3
