This study has extended a vehicle routing problem, with time-windows (VRPTW), by considering the randomness of the perishable food delivery process, and constructing a SVRPTWmodel, to obtain optimal delivery routes, loads, fleet dispatching and departure times for delivering perishable food from a distribution center. Our objective was to minimize not only the fixed costs for dispatching vehicl...

This vehicle routing problem involves finding a set of trips, one for each vehicle and to pick up known quantities of perishable goods from a set of geographically dispersed suppliers to the cargo terminal of an international airport in south India. The pickup time is based on the deterministic departure time of the flights. The objective of this Vehicle routing problem with Pickup and Delivery...

This paper considers the problem of scheduling a distributed network of production centers supplying a quickly perishable good that has to be produced just-intime and delivered within customer-specified strict time windows. The problem includes several planning, scheduling and routing problem, each notoriously affected by nearly prohibitive combinatorial complexity. Ideal solutions should provi...

Managing perishable food in a retail store is quite difficult because of the product’s short lifetime and deterioration. Many elements, such as price, shelf space allocation, and quality, which can affect the consumption rate, should be taken into account when the perishable food retail chain is designed. The modern tracking technologies provide good opportunities to improve the management of t...

– This paper derives a good approach to approximating the expected inventory level per unit time for the continuous review perishable inventory system. Three existing approximation approaches are examined and compared with the proposed approach. Three stockout cases, including the full backorder, the partial backorder, and the full lost sales cases, which customers or material users generally u...
