【摘要】：随着全球经济的日益发展,国际贸易、国际交流日趋频繁,伴随着贸易与人员流动的是货物在全球范围内的运输与流动。由于对运输时间的要求越来越高,航空运输便成了国际货物运输的首选。伴随着我国经济的高速增长,我国国际航空货物运输市场在近十几年不断增加,国外航空运输巨头也加强了中国市场的争夺战,我国国内航空运输企业虽然取得了一些进步,但与国外航空运输企业相比仍有不小的差距,效率低,差错率、货损率较高。国内货运企业要想在日益激烈的竞争中生存下来,必须协同合作,优化业务流程,提高效率,增强国际竞争力。本文以由中国国际货运航空有限公司承运的国际货物出港流程为研究对象,对出港流程进行了仿真与优化,具体章节安排如下:第一章:介绍了本文的研究背景、研究意义,并对航空货运流程优化相关文献及Petri网相关文献进行了研究与整理,然后对比、分析了现有的流程建模方法,并选择了Petri网作为本文的流程建模方法;第二章:介绍了Petri网基本原理、Petri网基本性质及Petri网分析方法,包括可达树分析、不变量分析与关联矩阵分析。第三章:梳理了国际航空货物出港流程,并画出了相关流程图,然后建立了国际航空货物出港流程的随机时间Petri网模型,并对建立的随机时间Petri网模型进行了关联矩阵分析,证明了模型的正确性。第四章:简要介绍了模型仿真平台,对模型进行了仿真,提出了国际航空货物出港流程的优化措施,并对比了优化前后的效率。第五章:对全文进行了总结,指出了本文研究的不足,并给出了未来的研究方向。
[Abstract]:With the development of global economy, international trade and international exchange are becoming more and more frequent. Air transport has become the first choice for international cargo transportation because of the higher and higher demand for transportation time. With the rapid economic growth of our country, the international air cargo transportation market of our country has been increasing continuously in the past ten years. Foreign air transport giants have also intensified the battle for the Chinese market. Although our domestic air transport enterprises have made some progress, However, compared with foreign air transport enterprises, there is still a large gap, low efficiency, error rate and high damage rate. If domestic freight enterprises want to survive in the increasingly fierce competition, they must cooperate with each other, optimize their business processes, improve their efficiency and enhance their international competitiveness. In this paper, the international cargo outbound process carried out by China International cargo Aviation Co., Ltd. as the research object, the port flow simulation and optimization, the specific chapters arranged as follows: chapter 1: introduced the research background, research significance, The related documents of air cargo flow optimization and Petri net are studied and sorted out. Then the existing process modeling methods are analyzed and Petri net is chosen as the process modeling method. Chapter 2: the basic principles of Petri nets and the analysis methods of Petri nets are introduced, including reachability tree analysis, invariant analysis and correlation matrix analysis. In chapter 3, the flow chart of international air cargo outbound is summarized, and then the stochastic time Petri net model of international air cargo outbound flow is established, and the random time Petri net model is analyzed by correlation matrix. The correctness of the model is proved. Chapter 4: the model simulation platform is introduced briefly, the model is simulated, the optimization measures of international air cargo outbound flow are put forward, and the efficiency before and after optimization is compared. Chapter 5: summarize the full text, point out the deficiency of this paper, and give the research direction in the future.
