Order Parameter Identification And Evolution Process Research Of Modular Logistics System

Logistics industry has become the third source of profit,its importance is self-evident.Logistics enterprises are also more concerned about how to make their services more diversified,play a more important role in logistics operation,and promote their own development.The collaborative development model of logistics system needs further research.In view of the existing problems and the insufficiency of the existing research,this paper takes the macro-logistics system of our country as the research object and the evolution process as the main research content from the perspective of modularization.On the one hand,from the perspective of system science,it puts forward the theoretical framework of the research on the evolution of modularized logistics system;on the other hand,it takes the self-organization theory as the theoretical basis to study the modularized logistics system.The identification of order parameters and the modeling of evolutionary process are studied.Firstly,the theoretical basis gives the definition and characteristics of modular logistics system,the main factors affecting the evolution and development of modular logistics system,and draws lessons from the model of product growth cycle,gives the growth cycle and stage characteristics of modular logistics system.Then the self-organization theory is introduced to demonstrate the applicability of self-organization theory to modular logistics system.Secondly,starting with the factors affecting the modular logistics system,the order parameters of the modular logistics system are identified by using the Haken model in Synergetics and the adiabatic elimination principle.The results show that the level of logistics standardization is the order parameter of modular log:istics system and the evolution of control system.Thirdly,taking the ratio of social logistics cost to GDP as a state variable,the evolutionary dynamic equation of modular logistics system is established based on cusp catastrophe model,and the evolutionary model is fitted by Cuspfit software.The results show that the standardization level of logistics as a sequence parameter determines the position of system catastrophe,and the turnover of goods as another control variable determines the degree of system catastrophe.Then,the potential function analysis of modular logistics system is carried out to describe the evolution process and trend of China's macro-logistics system,and to analyze its life cycle stages.The results show that China's macro-logisties system has undergone a sudden change in the system state in 2015 due to the revision of the evaluation criteria for A-level logistics enterprises.According to the analysis results,the countermeasures and suggestions to promote the coordinated and orderly development of modular logistics system in China are given.Finally,the main conclusions of the paper are summarized and the future research prospects are put forward in view of the shortcomings of the research.
