The pickup and delivery problem addresses the real-world issues in logistic industry and establishes an important category of vehicle routing problems. The problem is to find the shortest route to collect and distribute objects under the assumption that the total supply and the total demand are in equilibrium. This study formulates a new problem, called the selective pickup and delivery problem (SPDP),...
The design of distribution networks is one of the most important problems in supply chain and logistics management. The main elements in designing a distribution network are location and routing decisions. As these elements are interdependent in many distribution networks, the overall system cost can decrease if location and routing decisions are simultaneously tackled. In this paper, we consider...
Research on the problem of delivery route optimization and selecting the appropriate delivery route is an effective way of enhancing the response speed of logistics process, improving service quality, lowering logistics costs and upgrading efficiency. The problem of logistics delivery route optimization is an NP hard problem. Therefore, the use of traditional optimization method is difficult to obtain...
In studying the distribution routes, the paper first introduces the principle of distribution route optimization, and then presents the process and steps of saving hybrid genetic algorithm solving the distribution issue, and last realizes the algorithm raised in this paper by an algorithm example. Compared to the calculated results of other methods, it proves the superiority of saving hybrid genetic...
