- ItemAn investigation to evaluate the impact of quality-controlled logistics on food waste and food quality with the assistance of Internet of Things(Stellenbosch : Stellenbosch University, 2019-04) Joubert, Lelani; Louw, Louis; Stellenbosch University. Faculty of Engineering. Dept. of Industrial Engineering.ENGLISH 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.
- ItemTowards an internet-of-things framework for assisting quality-controlled-logistics decision making within the fresh produce supply chain(South African Institute for Industrial Engineering, 2018) Joubert, Lelani; Louw, LouisFresh food is mainly wasted due to overproduction and the natural decay of food quality which cannot be prevented. Hence, actors in the fresh food supply chain are responsible to monitor and control activities that influences the quality of fresh food. The emergence of new technologies such as Internet-of-Things (IoT) creates the opportunity to collect real-time food quality information, which may be used to assist and adapt logistic activities to ensure that food quality remains in the accepted quality limits. The aim of this paper is to identify current knowledge on quality-controlled logistics (QCL) in the fresh produce industry, and to identify whether there are opportunities to implement IoT-technologies, from the perspective of experts working in the fresh produce industry.
