Study On Ocean Shipping Operation Process Optimization Of China-Thailand Fresh Cold Chain Logistics

Based on the promotion of the "the Belt and Road" policy,as well as the geographical differences and complementary resources between China and Thailand,China Thailand bilateral trade cooperation has achieved remarkable results.In 2021,China became the largest trading partner of Thailand for the ninth year,with the trade volume between the two countries reaching US $131 billion,an increase of 33% year-on-year.Among them,the trade of fresh products is the most important part of the economic and trade cooperation between the two countries.Even in 2020,when the epidemic broke out on a large scale,the import and export trade volume of fresh products between China and Thailand did not stop growing,increasing by 15% and 42.9% respectively over the same period.In order to meet the growing trend of the trade volume of fresh products between China and Thailand,the logistics market of fresh and cold chain between China and Thailand is expanding.As the logistics transportation mode with the largest transportation volume,Sino Thai fresh and cold chain logistics shipping has developed rapidly.The expansion of Sino Thai fresh and cold chain logistics market not only brings good development opportunities to the marine operation of fresh and cold chain logistics,but also puts forward higher development requirements.The shipping operation of Sino Thai fresh and cold chain logistics belongs to cross-border transportation,which has the characteristics of long transportation distance,many transportation links,miscellaneous transportation and customs clearance procedures,high transportation risk and more difficult to control temperature control.Therefore,how to complete the shipping operation of Sino Thai fresh and cold chain logistics with high quality and efficiency has become a topic of great concern to port enterprises at present.Many studies have shown that the current shipping operation of Sino Thai fresh and cold chain logistics has a series of problems,such as miscellaneous operation process,low efficiency and so on.In order to accurately identify the specific links leading to the existing problems in the shipping operation of Sino Thai fresh and cold chain logistics and put forward the optimization strategy,this paper constructs the shipping operation process model of Sino Thai fresh and cold chain logistics based on Petri net,and uses the anylogic simulation system to simulate the model,so as to carry out the Optimization Research on the shipping operation process of Sino Thai fresh and cold chain logistics.This paper includes six chapters: the first chapter is the introduction,which mainly introduces the research background and significance,literature review at home and abroad,research objectives and research contents,technical route and research methods,and puts forward the innovation of the paper.The second chapter is the basic concepts and theoretical methods of marine operation of fresh cold chain logistics.Firstly,it expounds the connotation and characteristics of fresh cold chain logistics and marine operation,and then introduces the process modeling and optimization methods;The third chapter is the analysis of shipping operation process of Sino Thai fresh and cold chain logistics.Firstly,it introduces the development status of Sino Thai fresh and cold chain logistics,then analyzes the existing process of shipping import and export operation of Sino Thai fresh and cold chain logistics,and puts forward the existing problems;The fourth chapter is the construction of the shipping operation process model of Sino Thai fresh and cold chain logistics.The shipping import and export operation process of Sino Thai fresh and cold chain logistics is modeled and analyzed based on Petri net and incidence matrix method;The fifth chapter is the optimization of the shipping operation process of Sino Thai fresh and cold chain logistics.It uses the anylogic simulation system to simulate and optimize the shipping import and export operation process of Sino Thai fresh and cold chain logistics,and puts forward the corresponding optimization strategies for the specific links of the problems in the process.The sixth chapter is the conclusion,which mainly includes the summary of the article,the shortcomings and prospects of the article.
