【摘要】：港口是联接水陆运输的枢纽，也是国际贸易往来各类货物的集散地，在国际贸易中占据着重要位置，，随着我国经济的稳定增长以及国际贸易的迅猛发展，港口间的竞争愈加激烈，港口的业务能力管理对港口的竞争力提高具有重要的作用，也是港口竞争的核心环节，本文从供应链角度对港口的业务流程进行了分析，以Petri网作为建模手段对流程进行分析和优化，改善业务流程操作中存在的不合理环节，提高了港口供应链的运作效率，具有重要的理论研究价值和实践意义。首先，本文从国内外的供应链管理现状及Petri网用供应链模型构建的研究出发，介绍了课题研究的背景及意义，对文章的相关理论基础进行了整理和总结，为下文的模型构建和分析奠定了基础。其次，对港口供应链环境下的业务流程进行了剖析。介绍了港口供应链含义及特点，对港口供应链管理现状进行了分析，进而对港口供应链结构模型进行构建，从供应链角度分析港口的业务流程。再次，基于上文对供应链环境下的业务流程分析，介绍如何利用Petri网构建业务流程模型、如何运用Petri网的特性证明模型的正确性、对模型的时间性能进行分析以及提出了模型的优化方法。接着，针对秦皇岛港的业务流程状况，利用文章提出的方法，对秦皇岛港供应链业务流程进行了模型构建，找出模型中存在的同步及冲突关系的环节，运用优化规则对流程进行优化，提出了优化措施，利用模型的时间性能分析，比较优化前后的运行时间，证明优化的有效性，从实证角度阐述了本文的实践价值。最后，在总结全文的同时，也提出了文章中存在的不足及进一步的研究方向。
[Abstract]:The port is the hub for the transportation of water and land , and it is an important part of international trade . With the steady growth of our economy and the rapid development of international trade , the competition between ports is becoming more and more intense , and the port ' s business capacity management plays an important role in the competitiveness of the port , and it is also the core link of port competition .

First , based on the research of supply chain management and supply chain model construction at home and abroad , this paper introduces the background and significance of the subject research , summarizes and summarizes the relevant theoretical foundation of the article , and lays a foundation for the model construction and analysis below .

Secondly , the paper analyzes the business process under port supply chain environment , introduces the meaning and characteristics of port supply chain , analyzes the current situation of port supply chain management , and constructs the model of port supply chain structure , and analyzes the business process of port from the angle of supply chain .

Thirdly , based on the analysis of the business process under the supply chain environment , the paper introduces how to construct the business process model with Petri net , how to use Petri net ' s characteristics to prove the correctness of the model , analyze the time performance of the model , and put forward the optimization method of the model .

Then , aiming at the business process condition of Qinhuangdao Port , this paper constructs a model for the supply chain business process of Qinhuangdao Port , finds out the link between the synchronization and the conflict in the model , optimizes the process by using the optimization rule , analyzes the time performance of the model , compares the running time before and after the optimization , and proves the effectiveness of the optimization , and expounds the practical value of this paper from the empirical perspective .

Finally , at the same time , the author also puts forward the deficiency and further research direction in the article .
