Research On Task Allocation Of Joint Delivery Of Online Shopping Logistics Based On Multi-agent System

Online shopping logistics is a common distribution by a number of online shopping logistics enterprises to complete the same online shopping logistics and distribution tasks of the logistics model,the effective distribution of the Internet shopping logistics is the basis for the implementation of the common distribution guarantee.Common distribution task allocation is to decompose the logistics task assigned to the appropriate logistics enterprises to complete,but the logistics business independent intention and utility to the task allocation problem becomes complicated.The existing common distribution task allocation research is based on all the information of the known logistics enterprises and the assumption that the logistics enterprises have the consistency goal.They do not take into account the internal state and the external environment of the logistics enterprise change,and can not meet the common distribution of online shopping logistics The task allocation needs.Fortunately,MAS(Multi-Agent System,MAS)theoretical research to solve the online shopping logistics common distribution task allocation provides a favorable opportunity.Firstly,MAS is used as the research model of the common distribution system of online shopping logistics.The characteristics of the common distribution task of online shopping logistics and the characteristics of the common distribution system of online shopping logistics are discussed.The model of online shopping logistics enterprise agent model and online shopping logistics common distribution system is studied and discussed.Online shopping logistics common distribution system operating mechanism.Secondly,in order to have a unified cognitive standard and matching method for logistics resource capacity and task attributes in the distribution of online shopping logistics,the paper establishes a standardized description model of common distribution tasks and resource capability of online shopping logistics,and on the basis of the model This paper constructs the matching method of logistics task and resource ability.In view of the shortcomings of the task decomposition and task allocation,we propose the method of decomposing the common distribution task of online shopping logistics considering the constraints of logistics resources.Finally,the paper studies the problem of the distribution problem of the common distribution task of online shopping logistics,analyzes the shortcomings of MAS classic contract network agreement for the distribution of common distribution tasks of onlineshopping,and puts forward the improvement method.The dynamic model of logistics enterprises is introduced into the relationship and internal state And the establishment of a variety of bidding mechanism based on the expansion of the traditional contract network agreement based on the mental parameters.Based on the extended contract network agreement,the distribution mechanism of the common distribution task of online shopping and logistics is established,and an example is given for the distribution of the common distribution tasks of online shopping logistics enterprises in Chongqing And verifies the feasibility and validity of the task allocation mechanism.
