LOGISTICS CENTER LOCATION BASED ON FUZZY COMPREHENSIVE EVALUATION AND QUANTUM PARTICLE SWARM OPTIMIZATION

  • 摘要: 为提升物流配送中心选址结果的科学性和可行性,提出一种基于模糊综合评价和量子粒子群算法的物流中心选址策略。考虑众多定性因素,利用模糊综合评价法对候选物流中心进行综合评估,初步筛选一部分优质候选中心为后面模型求解做准备。以总投资效益最大化为目标,对初筛的优质候选中心建立数学模型,采用改进量子粒子群算法对模型进行求解得到最终的选址方案。通过仿真算例验证,该选址策略兼顾定性-定量因素对选址结果的影响,有效提升选址结果的科学性和可行性。此外,相较于对比算法,改进量子粒子群算法表现出更强的模型求解能力。

     

    Abstract: To improve the scientificity and feasibility of logistics distribution center location results, a logistics center location strategy based on fuzzy comprehensive evaluation and quantum particle swarm optimization is proposed. Considering many qualitative factors, the fuzzy comprehensive evaluation method was used to comprehensively evaluate the candidate logistics centers, and a part of high-quality candidate centers were preliminarily screened to prepare for the solution of the model. With the goal of maximizing the total investment benefit, a mathematical model was established for the high-quality candidate centers in the initial screening, and the improved quantum particle swarm optimization was used to solve the model to obtain the final location scheme. Through the simulation example verification, the location strategy takes into account the influence of qualitative and quantitative factors on the location results, and effectively improves the scientificity and feasibility of the location results. In addition, compared with the comparison algorithms, the improved quantum particle swarm optimization shows stronger model solving ability.
