Addressing the Location Problem of a Perishables Redistribution Center in the Middle of Europe

Abstract

This work aims to contribute to the debate on practical utilization of different location models for consolidation, redistribution, and repackaging centers in a supply chain to optimize shipments, thereby reducing food loss and waste, within the framework of quality of customer service improvement. The scenario in question is the creation of a redistribution center for highly perishable products (fruits and vegetables) from southeast Spain—the leading European supplier—for customers throughout Europe. It is estimated that 10% of exports (more than 530,000 metric tons) from this area are returned by customers due to minor defects. These products cannot be reused and are therefore wasted. Regarding the methodology, comparisons were made between the p-median, gravity p-median, and p-center models. Scenarios of change in demand and randomness in distances were also tested. In addition, the modelling used included the cost and time within a multicriteria optimization framework to assess the possibility of a transport mode change. It was observed, for example, that the gravity p-median model proved useful for perishable products and the logistics strategy chosen. Furthermore, the p-median model displayed strong robustness against long-term changes in demand and random distances. In general, it was demonstrated that this strategy would successfully reduce the response time and distance of shipment from the distribution center to the customers and thereby improve sustainability of the service, reducing the waste related to direct shipments. Furthermore, this research also demonstrated the difficulty of using intermodality in this context, mainly due to transit time, which would undoubtedly increase the waste generated.

A Decision Method for Benefit Distribution Mechanism of Shared End Distribution on Shapley Value

“…For the “theme of shared terminal distribution,” scholars have mainly focused on the following three aspects: site selection for terminal distribution outlets, the optimization of terminal distribution path, and research on sharing terminal distribution mode. Perez-Mesa et al [ 6 ] established a location selection model for FMCG's agricultural product distribution center with the lowest total cost. Zhang and Liu [ 7 ] proposed the method of a gray demand logistics distribution center location and model of a gray sales demand logistics distribution center location planning, which can solve the problem of gray sales demand in logistics distribution center location.…”

Research on Optimizing the Location and Layout of National Emergency Material Reserve

“…Scholars have gradually applied the p-center problem to specific problems. Considering the possible damage of emergency facilities for sudden disasters, the academic community began to expand the research on the original P-center problem and put forward a variety of optimization algorithms for solving P-center to shorten the delivery distance [11,12]. Then, they began to consider the problem of minimizing the maximum of the nth shortest distance from the relief point to the reserve point.…”

Mitigating Environmental Impact of Perishable Food Supply Chain by a Novel Configuration: Simulating Banana Supply Chain in Sri Lanka

“…Various studies have been performed on finding approaches to make the perishable food supply chain sustainable. Economic sustainability has been studied, focusing on productivity [6][7][8][9][10][11], profit [12][13][14][15][16][17][18][19][20][21][22][23], cost [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40], and revenue optimization [41,42].…”
