The distribution of finished products from depots to customers is a practical and challenging problem in logistics management. Better routing and scheduling decisions can result in higher level of customer satisfaction because more customers can be served in a shorter time. The distribution problem is generally formulated as the vehicle routing problem (VRP). Nevertheless, there is a rigid assu...

In this chapter we are going to study metaheuristics based on the Automata Theory for the Multi-objective Optimization of Combinatorial Problems. As well known, Combinatorial Optimization is a branch of optimization. Its domain is optimization problems where the set of feasible solutions is discrete or can be reduced to a discrete one, and the goal is to find the best possible solution(Yong-Fa ...

As pointed out by Nagy and Salhi in their recent survey [1], many variants of the location routing problem (LRP) are addressed in the literature. Generally speaking the LRP consists of determining locations for depots from which customers are served on routes with the objective of minimizing the overall cost. In this talk we consider the capacitated locationrouting problem (CLRP) which is defin...

This research present a set-partitioning heuristic to generate populations in a hybrid genetic algorithm (hGA) which is able to solve four different variants of the vehicle routing problem: the multi-depot vehicle routing problem (MDVRP), the heterogeneous fleet and mix decisions (type, size and number of vehicle) (HFMVRP), site dependent vehicle routing problem (SDVRP) and the asymmetric vehic...

This paper studies the distribution of emergency relief for electric vehicles (EVs), which considers energy saving, multi-depot, and vehicle routing problems with time windows, named saving-oriented multi-depot problem windows (ESMDVRPTW). Our aim is to find routes EVs such that all shelter demands are fulfilled during their total cost traveled by fleet minimized. To this end, we formulate ESMD...

The properties of the depot fats of animals depend, to some extent, upon the nature of the dietary fats. Thus it was shown by Anderson and Mendel (1) that feeding of highly unsaturated oils results in the deposition of a body fat of high iodine number, whereas the administration of “hard” fat in the diet leads to a decrease in the iodine number of the depot fats. Recently Longenecker and Hildit...
