【摘要】：作为“第三方利润源泉”,物流配送一直广受世界各大行业的重视,许多流通企业、生产企业都建立起了专属的物流配送中心,用来加强自身对客户的统一管理,提高配送效率,专业化程度和服务水平,并借此降低成本。本文所选的医药物流是一个流通性和时效性极强的行业,其配送一般具有小批量、多品种、多频次的特点。但是我国医药物流起步较晚,专业化程度不高,物流成本高,所以在节约物流成本上有很大的潜力。随着我国市场经济的不断发展,各行业也对物流配送提出了更高的要求。企业除了需要重视提高物流配送效率和降低成本之外,同样需要考虑客户的个性化要求,实现客户满意度的最大化。本文首先对车辆调度问题进行概述,然后研究了医药物流行业的配送流程,分析了医药物流行业的配送特点及存在问题。根据医药物流行业时效性强的特点,在分析影响客户满意度因素的基础上提出客户满意度重要指标的模糊隶属函数,其中主要研究时间对医药物流车辆调度的影响。并将客户时间满意度函数转化为时间惩罚成本函数,建立统一目标最小化的车辆调度模型,目标是使运输成本最小和时间满意度最大,也就是时间惩罚成本最小。本文通过对两个目标赋予不同的权重来寻求服务成本与服务水平的均衡点。本文的创新点在于添加了最大时间惩罚成本约束条件,使配送车辆的惩罚成本都不能超过最大的时间惩罚成本,这样客户可接受服务。接下来设计了带有时间窗的节约算法对模型进行求解,并用一个案例对该模型的可操作性进行了验证,得出了满意的车辆调度路线,说明带时间窗的节约算法对解决时效性强的医药物流行业的车辆调度问题有一定的可行性。在针对医药物流配送中心的车辆调度问题领域,本文的研究成果具有一定的参考意义。
[Abstract]:As a "source of third party profit", logistics distribution has been attached great importance by every major industry in the world. Many circulation enterprises and manufacturing enterprises have set up exclusive logistics distribution centers to strengthen their unified management of customers and improve the efficiency of distribution. The pharmaceutical logistics selected in this paper is an industry with high liquidity and timeliness, and its distribution is generally of small batches, many varieties, The characteristic of multi-frequency. But the medical logistics of our country starts late, the degree of specialization is not high, the logistics cost is high, so there is great potential in saving the cost of logistics. With the development of market economy in our country, Enterprises not only need to pay attention to improving the efficiency of logistics distribution and reducing costs, but also need to consider the individual requirements of customers. To maximize customer satisfaction, this paper first summarizes the vehicle scheduling problem, and then studies the distribution process of the pharmaceutical logistics industry. This paper analyzes the distribution characteristics and existing problems of the pharmaceutical logistics industry. According to the characteristics of the pharmaceutical logistics industry, based on the analysis of the factors affecting customer satisfaction, the fuzzy membership function of the important index of customer satisfaction is put forward. The influence of time on vehicle scheduling in pharmaceutical logistics is mainly studied, and the customer time satisfaction function is transformed into time penalty cost function, and a vehicle scheduling model with uniform goal minimization is established. The goal is to minimize transport costs and maximize time satisfaction, This paper seeks the equilibrium point between service cost and service level by assigning different weights to the two objectives. The innovation of this paper is to add the constraint condition of maximum time penalty cost. So that the penalty cost of the distribution vehicle can not exceed the maximum time penalty cost, so that the customer can accept the service. Then, a saving algorithm with time window is designed to solve the model. The maneuverability of the model is verified by a case, and a satisfactory vehicle scheduling route is obtained. The result shows that the algorithm with time window is feasible to solve the vehicle scheduling problem in pharmaceutical logistics industry. In the field of vehicle scheduling problem for medical logistics distribution center, The research results of this paper have certain reference significance.
