Research on Multi-Depot Location Routing Problem with Backhauls and Soft Time Windows
摘要
Abstract
Location routing problems is not only of great significance in integrated logistics network planning research , but also an important management decision that every large logistics company has to make .Based on the warehouse capacity and vehicle capacity constraints , the paper proposes a multi-depot location routing prob-lem model(MDLRP)with backhauls and soft time windows .The model takes full consideration of logistics distri-bution mode with the simultaneous delivery and pick-up and the customer service time requirements .Given the complexity of the MDLRP model , the paper proposes an improved hybrid genetic algorithm with iterated local search and recombination strategy to solve the model integrally .The performance of the heuristic is assessed by computational experiments .As can be seen from the solution , the model with its hybrid genetic algorithm is feasible and superior , and it can be provided to be an alternative tool for location and routing decision .关键词
