【摘要】：2009年,我国颁布了《物流业调整和振兴规划》,这为物流行业实现跨越式发展提供了契机。2014年,我国物流业更是迅速发展,社会物流总额比2013年增长7.9%。在物流业迅速发展的环境下,物流配送中心有着举足轻重的位置,然而我国物流配送体系存在诸如流程规范性差、配送成本高、配送效率低下、管理制度落后、配送中心基建不完善等问题。这些问题极大制约了物流配送的发展。现如今,如何降低配送成本、提高系统运作效率和有效管理配送业务流程都是亟待解决的问题。本文对物流配送和Petri网建模的国内外研究现状进行了归纳和分析,明确了论文选题的背景和意义。经过对业务流程的多种建模方式进行仔细对比和分析,本文最终确定用面向对象Petri网对业务流程进行建模。面向对象Petri网具有面向对象技术和传统Petri网的双方面优点,非常适合业务流程的分析和建模。本文详细分析了典型的物流配送中心的业务流程模式,对具体作业流程进行了分析,并绘制了流程图,然后确定了本文的研究对象是存在问题较多且急需解决的出库环节。利用面向对象Petri网的建模方法建立了物流配送中心出库流程的Petri网模型,并应用“关联矩阵分析法”对所建模型的性质进行了求解和分析,证明所建的模型是正确的、可用的。本文针对物流配送中心存在的问题,从多个角度对物流配送中心出库环节进行了优化,并建立了优化后的面向对象Petri网模型。而后本文以流程完成的平均时间作为参数,利用ExSpect仿真工具对优化前后的Petri网模型进行仿真与对比,证实了本文提出的优化措施是有效的、可行的。为使仿真结果更加切合实际情况,对面向对象Petri网模型引入随机变量,进一步论证优化措施的有效性和可行性。
[Abstract]:In 2009, China promulgated the "Plan for Adjustment and Revitalization of Logistics Industry", which provides an opportunity for the development of logistics industry by leaps and bounds. In the environment of rapid development of logistics industry, logistics distribution center plays an important role. However, the logistics distribution system of our country has some problems such as poor flow standard, high distribution cost and low distribution efficiency. Problems such as backward management system, imperfect infrastructure of distribution center, and so on. These problems have greatly restricted the development of logistics distribution. Nowadays, how to reduce the cost of distribution, It is urgent to improve the operational efficiency of the system and effectively manage the distribution business process. This paper summarizes and analyzes the domestic and foreign research status of logistics distribution and Petri net modeling. The background and significance of the selected topic are clarified. After careful comparison and analysis of various modeling methods of business process, In this paper, the object oriented Petri net is used to model the business process. The object oriented Petri net has the advantages of object oriented technology and traditional Petri net. It is very suitable for business process analysis and modeling. This paper analyzes the business process model of typical logistics distribution center in detail, analyzes the specific operation process, and draws the flow chart. Then it is determined that the research object of this paper is the exit link which has many problems and needs to be solved. By using the object-oriented Petri net modeling method, the Petri net model of logistics distribution center outbound process is established. The properties of the model are solved and analyzed by using the method of correlation matrix analysis. It is proved that the model is correct and available. This paper aims at the problems existing in the logistics distribution center. This paper optimizes the outbound link of logistics distribution center from several angles, and establishes the optimized object-oriented Petri net model. Then, the average time of process completion is taken as the parameter. The simulation and comparison of Petri net model before and after optimization by using ExSpect simulation tool prove that the optimization measures proposed in this paper are effective and feasible. In order to make the simulation results more suitable for the actual situation, random variables are introduced into the object-oriented Petri net model. Further demonstrate the effectiveness and feasibility of optimization measures.
