【摘要】：随着经济的飞速发展,人们对物流行业产生了巨大的需求。物流行业从最初的第一方物流(The first Party Logistics,简称1PL)、第二方物流(The second Party Logistics,简称2PL)发展到第三方物流(The third Party Logistics,简称3PL),但是由于3PL只单纯地提供物流服务,它们的供应商的技术、战略和扩展能力有限,它们的物流资源和信息不能全面共享,所以3PL难以实现对整个供应链的优化集成,于是第四方物流(The fourth Party Logistics,简称4PL)应运而生。4PL是供需双方及第三方物流的领导力量,它依靠优秀的3PL物流供应商、技术供应商、管理咨询等有效得整合资源,提供一套完整的供应链解决方案,为客户降低成本的同时自己获得一定的利润。4PL的运作模式分为协同运作型、方案集成型、行业创新型和动态联盟型。本文针对方案集成型的4PL运作模式,考虑了资金有限的情况,研究了成本受限的最大化客户满意度的4PL网络优化问题。论文在对相关研究和理论概述基础上进行了以下工作。首先,本文采用运筹学中图论的知识和效用理论的知识构建了问题的数学模型。其次,本文采用带有自适应变异因子和自适应交叉因子的DE/best/2/bin形式的差分进化算法以及带有两阶段调整策略的最小费用最大流算法解决了该问题。最后,针对不同规模的第四方物流网络问题进行仿真,并与标准差分进化算法的结果对比分析,验证了改进后的差分进化算法对不同规模问题的适用性较好。同时,本文针对不同的成本上限值、客户服务水平要求值以及行为参数进行了仿真与分析,结果表明：1)客户满意度随着客户服务水平要求值的增大而减小,随着成本上限值的增大而增大；2)当面对收益时,客户对收益的增加越敏感,每个点得到的客户服务水平越分散,反之越集中；当面对损失时,客户对损失的减小越敏感,每个点得到的客户服务水平越分散,反之越集中；3)客户对损失越敏感,4PL为客户每个需求点提供的客户服务水平越集中,反之越分散。
[Abstract]:With the rapid development of economy, people have a huge demand for the logistics industry. The logistics industry has evolved from the first party, the first Party logistics, and the second party, the second Party logistics, to the third party, the third Party logistics, but because 3PL only provides logistics services, their suppliers have the technology. The strategy and expansion ability is limited, their logistics resources and information can not be fully shared, so it is difficult for 3PL to realize the optimal integration of the whole supply chain. So the fourth party logistics, the fourth Party logistics, came into being. 4PL is the leading force of the supply and demand parties and the third party logistics. It relies on excellent 3PL logistics suppliers, technical suppliers, management consulting and so on to effectively integrate resources. To provide a complete supply chain solution for customers to reduce costs and earn a certain profit. 4PL mode of operation can be divided into collaborative operation, solution integration, industry innovation and dynamic alliance. In view of the scheme integrated 4PL operation mode, this paper considers the case of limited capital, and studies the 4PL network optimization problem of maximizing customer satisfaction with limited cost. On the basis of the relevant research and theoretical overview, the following work has been done in this paper. Firstly, the mathematical model of the problem is constructed by using the knowledge of graph theory and utility theory in operational research. Secondly, the differential evolution algorithm in DE/best/2/bin form with adaptive mutation factor and adaptive crossover factor and the minimum cost maximum flow algorithm with two-stage adjustment strategy are used to solve the problem. Finally, the fourth party logistics network with different scales is simulated, and compared with the results of standard differential evolution algorithm, the applicability of the improved differential evolution algorithm to different scale problems is verified. At the same time, this paper simulates and analyzes different cost upper limit values, customer service level requirements and behavior parameters. The results show that customer satisfaction decreases with the increase of customer service level requirement. The more sensitive the customer is to the increase in revenue, the more scattered the customer service level is at each point, and the more concentrated the customer is when faced with the loss, the more sensitive the customer is to the reduction of the loss. The more decentralized the customer service level is, the more sensitive the customer is to the loss, the more centralized the customer service level is, the more dispersed the customer service level is.
