Abstract
The issue of preserving fresh food during the transportation is one of the long-standing issues for food distributors. On the other hand, the issue of vehicle routing is one of the most important issues in distribution management. Affecting the quality of food is the distribution process, which reduces the distribution time through vehicle routing plays an important role in reducing food spoilage. Therefore, in this study, the problem of vehicle routing in the distribution of perishable food materials is investigated. The time is different so that the distance is minimized and the capacities and time windows are not violated. This research aims to find facilities, identify the size of each cargo, and establish the most efficient vehicle routes to reduce overall costs at three levels in the event of a system failure. Undoubtedly, the traveling salesman issue is one of the most famous issues in the field of artificial intelligence.
Highlights
Today, competitive markets and the development of management concepts have forced companies to better design and manage supply chains
This study examines the design of a perishable food supply chain network with disruption risk, which includes facility location, flow allocation between facilities, and routing decisions
The purpose of this study is to provide a traveling salesman problem (TSP) model for locating distribution centres along with routing distribution vehicles from suppliers to demand points
Summary
Competitive markets and the development of management concepts have forced companies to better design and manage supply chains. Because to increase the efficiency of a supply chain, its decisions cannot be considered separately and optimized. Since the high role of the location factor, routing is not covered in the survival of a supply chain, so the integration of these elements will provide an efficient and effective supply chain (Elluru et al, 2019; Shavarani, 2019; Thürer et al, 2020). This study examines the design of a perishable food supply chain network with disruption risk, which includes facility location, flow allocation between facilities, and routing decisions. Food distribution centres receive food from supply points and deliver it to demand centres. The purpose of this study is to provide a traveling salesman problem (TSP) model for locating distribution centres along with routing distribution vehicles from suppliers to demand points. The more attention is paid to the cost, the more coverage we will have and we can cover all areas with the highest cost
