Online auction is becoming more and more popular in electronic commerce (EC). It has become the mainstream trading methods in consumer to consumer (C2C), such as eBay. The steady collaboration field and common concept of exchange may be formed in the cooperation of the Multi-Agent system(MAS), then the agents will have so much common knowledge in order to complete the tasks. The member of MAS has both cooperation and self-interest. Based on the analysis of the cooperation and competition of the participators in the online auction, the concept of overtime and history information is introduced. As existing incomplete information, the efficiency of the auction is low without consider the history information. This paper put forward a MAS flow frame and negotiation algorithms that make the bidders of the auction participate in the negotiation honestly and actively. Both the efficiency and transparency among the participators have been enhanced.

Multi-Agent negotiation system in online auction

How to make a faster and more efficient task assignment is a hot issue in the multi-UAVs coordination area, by using the Tactical Digital Information Links (TADILs) to share and exchange combat information in modern aerial warfare. Due to the shortage of traditional contract net, a filter model is proposed according to the negotiation mechanism of contract net protocol theory by R.G. Smith [1], which builds the task assignment model, and defines the restrictions of UAV to extend the framework of contract net. Simulation results show that the extended contract net can significantly reduce the communication traffic and optimize the efficiency of decision-making.

Task Assignment for Multi-UAV Using Contract Net Based on Filter Model

Agent Persuasion Mechanism of Acquaintance

The contract net model is used for distributed problem solving and task allocation in application systems based on agent. To overcome several defects in solving real problem, a concept of task acquaintance is introduced,then a extention of the contract net model is presented,which chooses strategy dynamically during negotiation. The strategy of negation based on task acquaintance can reduce cost of communication, and can compute effectively during negotiation.

An Extension of Contract Net Model Based on Task Acquaintance

With the popularization of the Internet and the vigorous development of e-commerce, e-commerce has become an important driving force for economic development. However, the lagging logistics and distribution seriously hinder the development of e-commerce. In order to create a good environment for the development of e-commerce and promote the development of e-commerce, the issue of smart logistics and distribution under the Internet platform has become the focus of the public. This paper compares the three logistics distribution modes of self-operated logistics, third-party logistics and logistics alliance, and relies on ant colony algorithm to optimize the logistics distribution path.

Based on the mode of manufacturers dominating in the forward supply chain and retailers dominating in the backward supply chain, a hybrid leading closed-loop supply chain structure with different two-way dominance is constructed to study the advantages and disadvantages of supply chain decision-making under logistics self-supporting and logistics outsourcing modes. Stackelberg game theory is used to solve the equilibrium solution and optimal profit of the forward and backward supply chains under different logistics modes. On this basis, the profits of manufacturers and retailers in the forward and backward closed-loop supply chains are compared, and finally, the conclusion is verified by numerical examples. The influence of different logistics modes on pricing decisions of manufacturers and retailers is studied based on the dual-agent hybrid dominant supply chain model, and then, the logistics mode selection of manufacturers and retailers under different conditions of forward dominant body and backward dominant body.
