dc.description.abstractENGLISH SUMMARY: Fresh food is mainly wasted due to overproduction and the natural decay of food quality, which cannot be prevented but is accelerated by poor supply chain management. Therefore, actors in the fresh produce supply chain are responsible for monitoring and controlling logistic activities that influence the quality of fresh food. The emergence of new technologies such as the Internet of Things provides the ability to collect real-time food quality information, which may be used to assist and adapt logistic activities to ensure that food quality remains within the accepted quality limits. However, limited literature is available to gain sufficient understanding on how Internet of Things technologies and quality-controlled logistics can be combined to potentially reduce food waste along the fresh produce supply chain and to improve overall food quality. The purpose of this research study is to investigate the impact of quality-controlled logistics on food waste in the fresh produce supply chain. Thereafter, the study will explore how quality-controlled logistics can be implemented with the use of Internet of Things technologies. Expert insights regarding quality-controlled logistics and the Internet of Things were collected to determine (i) how traditional logistics could be adapted to implement qualitycontrolled logistics in the fresh produce supply chain; and (ii) to identify whether the experts believe that Internet of Things technologies could assist supply chain planning in the fresh produce industry. Simulation modelling was used to evaluate the impact of several quality-controlled logistics activities on food waste and food quality. It was found that the implementation of the Least-Shelf-life-First-Out with dynamic pricing replenishment strategy at the retail stores, would result in a significant reduction in food waste throughout the supply chain; however, it slightly reduced the remaining shelflife of the purchased fresh produce. An Internet of Things prototype application was also developed to illustrate how emerging technologies could assist the implementation of quality-controlled logistics in the fresh produce supply chain, and to highlight the practical challenges that should be considered before implementing such applications. The findings from this study contribute towards research on food supply chain management, by documenting how quality-controlled logistics and the Internet of Things can contribute to the reduction in waste in the fresh produce supply chain.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: ars voedsel produkte word hoofsaaklik vermors weens oorproduksie en die natuurlike verval van die kwaliteit van die produk wat nie voorkom kan word nie, maar eerder versnel word deur swak voorsieningskettingbestuur. Daarom is rolspelers in die voedselvoorsieningsketting verantwoordelik om logistieke aktiwiteite wat die kwaliteit van vars produkte beïnvloed, te monitor en te beheer. Nuwe tegnologieë soos die Internet van Voorwerpe skep die geleentheid om inligting rakend die kwaliteit van vars produkte in reële tyd in te samel. Dit kan gebruik word om logistieke aktiwiteite aan te pas om te verseker dat die kwaliteit van die vars produkte steeds in die aanvaarde gehalte perke bly. Daar is egter nog beperkte literatuur beskikbaar om voldoende insig te kry oor hoe Internet van Voorwerpe tegnologieë saam met kwaliteit-gedrewe logistieke aktiwiteite kombineer kan word sodat voedselvermorsing kan verminder en om die kwaliteit van vars produkte te verbeter. Die doel van hierdie navorsingstudie is om die impak van kwaliteit-gedrewe logistieke aktiwiteite op voedselvermorsing asook die kwaliteit van vars produkte te evalueer. Daarna sal die studie ondersoek instel om te bepaal hoe kwaliteit-gedrewe logistieke aktiwiteite geïmplementeer kan word saam met die gebruik van Internet van Voorwerpe tegnologie. Kenners wat in die vars produksiebedryf werk se kennis oor kwaliteit-gedrewe logistiek asook die Internet van Voorwerpe was ingesamel om te bepaal (i) hoe tradisionele logistieke aktiwiteite aangepas kan word om kwaliteit-gedrewe logistieke aktiwiteite in die vars voedselvoorsieningsketting te implementeer; en (ii) om die kenners se opinie te kry ten opsigte van die gebruik van Internet van Voorwerpe in die vars produksiebedryf. Simulasie modellering was gebruik om die impak wat verskeie kwaliteit-gedrewe logistieke aktiwiteite op voedselvermorsing asook voedselkwaliteit het, te evalueer. Daar is bevind dat die implementering van die Minste-Rakleeftyd-Eerste-Uit met 'n dinamiese prysbepaling strategie by kleinhandelaars 'n beduidende vermindering van voedselvermorsing tot gevolg sal hê, maar die oorblywende rakleeftyd van die vars produkte tydens verkope sal effens verminder word. 'n Internet van Voorwerpe toepassings prototipe was ontwikkel om te illustreer hoe nuwe tegnologieë die implementering van kwaliteit-gedrewe logistiek kan bevoordeel en om die praktiese uitdagings wat oorweeg moet word, uit te lig. Die bevindinge van hierdie navorsingstudie maak 'n bydra tot die navorsingveld voedselvoorsieningskettingbestuur, deur bewustheid te skep oor hoe kwaliteit-gedrewe logistieke aktiwiteite en die Internet van Voorwerpe 'n bydra lewer tot die vermindering van voedselvermorsing.af_ZA
