可持续发展理念下的配送中心选址模型及算法研究

Models and Algorithms for Locating Distribution Center in Consideration of Sustainability

配送中心选址对物流运作产生重要影响.随着市场竞争的不断加剧、社会环保意识的不断增强,配送中心选址不仅仅需要考虑成本,还需要考虑服务水平、环境影响等因素.该文以FCLP模型为基础,建立了以物流成本最小化、服务可靠度最大化和CO2排放最小化为目标的配送中心选址模型,并运用NSGA-Ⅱ对模型进行了求解.算例分析表明,NSGA-Ⅱ算法不仅能够快速求得问题的Pareto最优解,而且与传统优化算法相比,得到的解也具有更优性.

Location decision of distribution centers has critical influence on logistics performance .Re‐cent concerns regarding commercial competition and environmental pollution ,gradually ,are shifting the fo‐cus of modelling to incorporate not only economic cost but also service level and carbon emissions .Based on the FCLP ,a location model which includes three objectives‐logistics cost minimization ,service reliability maximization and CO2 emissions minimization‐is proposed .T he NSGA‐Ⅱ algorithm is adopted to solve the proposed model ,and test results show that NSGA‐Ⅱ algorithm can obtain Pareto optimal solutions effi‐ciently and better performance notably in contrast with some traditional optimization techniques .
