The Multi-objective Vehicle Routing Problem (MoVRP) is an important problem in the logistics distribution management, whose two objective functions are to minimize the global transportation cost and to maximize the average customer satisfaction. The mixed integer programming model of MoVRP is proposed in this paper. And a Hybrid Genetic Algorithm based on Human-Computer Interaction (HGAHCI) is presented...
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...
Location-routing problem (LRP) is a combinational optimization problem in a logistics system. Most heuristic methods employed for LRP is dividing the problem into location assignment and vehicle routing with a two-phase method, but this method often does not lead to a satisfactory result for the information can not be compressed from one phase to the other efficiently. In this paper we are concerned...
The traditional vehicle scheduling is not easy to satisfy with the real demand of logistics distribution under electronic commerce. Therefore, according to the particularity of logistic distribution under electronic commerce, multi-depot vehicle routing problem with time windows model is built. For MDVRPTW is NP puzzle, the improved Two-Phase Algorithm needs to be adopted to get solutions. Namely,...
The vehicle routing problem of logistics distribution is indispensability contents in logistics distribution optimization. In order to satisfy with the individual and various demand of customer, establish single and mixed fleet multi-depot vehicle routing problem with backhauls model. According to the characteristics of model, hybrid genetic algorithm is used to get the optimization solution. First...
Vehicle route problem of logistics distribution is the important step optimizing logistics distribution. According to the traditional genetic algorithm shortcomings of slowly convergent speed, weakly partial searching ability and easily premature, therefore, hybrid genetic algorithm is used to get the optimization solution, namely, use dualistic coding so as to simplify the problem and improve the...
With the intensification of market competition and fast development of science and technology, many enterprises have begun to realize the importance of logistic distribution vehicle routing problem under uncertainty environment, and begin to pay more attention to the research of this problem. In this paper, The traditional vehicle routing problem with time windows is expanded to the situation that...
