Research On The Wan Xiang Aviation Cold Chain Logistics Process Optimization Based On Random Time Petri Nets

Cold chain logistics can ensure the food quality and provides the basic guarantee for the people's life, on the other hand can satisfy the people diversification demand of the fresh food and improve the people's life satisfaction. Air cold chain transport due to its features of highest efficiency and security,became the key point of developing vigorously in china quickly. While the air cold chain transportation starts late in our country, there are deficiencies in all aspects.So This paper from the process perspective to study the cold chain distribution.The current process modeling of logistics system have many ways of modeling, Based on the analysis of the distribution process based Wanxiang cold chain center of aviation of the cold chain, carries on the modeling process using the Petri net theory, and using the mathematical analysis method of Petri net, combined with the practical analysis of the model and optimization, the obtained model has proven to be active, boundedness and accessibility. There is certain reference function to the company.According to the air cold chain logistics and the problem of low efficiency, this paper puts forward the corresponding optimization measures, by changing the air logistics processes to achieve process optimization objective.
