【摘要】：近年来，，随着图书行业的不断开放和市场化运营，图书产业的市场竞争日趋激烈。这种转变不仅体现在企业发展战略上更趋网络化、集约化和柔性化，而且体现在更重视商流、物流、资金流和信息流一体化的供应链服务，还体现在信息技术、电子商务及物流系统的革新创造。物流作为第三利润源越来越受到各行业的重视。配送中心作为物流系统的节点和枢纽，能够充分发挥物流作为第三利润源的作用，降低成本和提高效益，从而保证整个供应链的顺畅平稳，增强图书产业链的市场竞争力。本文以图书配送中心的业务流程为研究对象，运用Petri网来对业务流程进行建模、分析和优化，找出流程中不合理的环节，并加以优化改进，从而提高图书配送中心的运作效率和降低运作成本，具有重要的理论研究价值和实践意义。首先，本文从国内外对配送中心、业务流程及Petri网研究的现状出发，介绍了课题研究的背景和意义，对本文的相关理论基础进行了整理和总结，为下文建模及优化分析奠定基础。其次，本文对图书配送中心的业务现状进行了剖析。介绍了图书配送中心的含义及特点，并对图书配送中心的管理及运作现状进行了分析。再次，基于上文对图书配送中心业务流程的分析，介绍了运用Petri网进行建模的原理及思路，使用Murata的六种简化规则来验证模型的正确性，并且对模型的时间性能进行了分析，同时，提出了模型的优化方法。接着，针对JFS图书配送中心业务流程现状，分析了其业务运作流程，建立了业务流程图，并使用Petri网对现有业务流程进行了建模。在验证了模型的正确性后，通过Petri网关联矩阵找出模型中存在的同步环节和冲突环节，并对其提出了优化措施。同时，计算模型的时间性能指标，通过对比分析模型优化前后的整体运行时间，来证明模型优化的有效性，从实证角度阐述了本文的实践意义。最后，在总结全文的同时，也提出了文章中存在的不足之处及需进一步研究的思路和方向。
[Abstract]:In recent years, with the continuous opening and market-oriented operation of the book industry, the market competition of the book industry is becoming increasingly fierce. This change is reflected not only in a more networked, intensive and flexible enterprise development strategy, but also in a supply chain service that pays more attention to the integration of business flow, logistics, capital flow and information flow, as well as in information technology. Innovation and creation of e-commerce and logistics system. Logistics, as the third profit source, is paid more and more attention by various industries. As the node and hub of the logistics system, the distribution center can give full play to the role of logistics as the third profit source, reduce the cost and improve the efficiency, so as to ensure the smooth and smooth supply chain and enhance the market competitiveness of the book industry chain. This paper takes the business process of the book distribution center as the research object, uses Petri net to model, analyzes and optimizes the business process, finds out the unreasonable link in the process, and optimizes and improves it. Therefore, it has important theoretical research value and practical significance to improve the operation efficiency and reduce the operating cost of the book distribution center. Firstly, this paper introduces the background and significance of the research on distribution center, business process and Petri net, and summarizes the theoretical basis of this paper. For the following modeling and optimization analysis laid the foundation. Secondly, this paper analyzes the business status of book distribution center. This paper introduces the meaning and characteristics of book distribution center, and analyzes the management and operation status of book distribution center. Thirdly, based on the analysis of the business process of the book distribution center above, this paper introduces the principles and ideas of modeling using Petri net, validates the correctness of the model by using six simplified rules of Murata, and analyzes the time performance of the model. At the same time, the optimization method of the model is proposed. Then, according to the present situation of the business process of JFS book distribution center, this paper analyzes its business operation process, establishes the business flow chart, and uses Petri net to model the existing business process. After the correctness of the model is verified, the synchronization and conflict links in the model are found through the Petri net association matrix, and the optimization measures are put forward. At the same time, the time performance index of the model is calculated, and the validity of the model optimization is proved by comparing and analyzing the whole running time before and after the model optimization. The practical significance of this paper is expounded from the empirical point of view. Finally, this paper summarizes the full text, also puts forward the shortcomings of the article and the need for further research ideas and directions.
