The study on international trade negotiation based on supply chain management

Abstract: This paper presents an agent-based multilateral negotiation protocol for supporting international trade negotiations in supply chain management. The proposed multilateral bargaining protocol, which extends from the Contract Net Protocol (CNP), divides the multilateral bargaining process into a series of steps to facilitate agents to reach a promising outcome. It involves four predefined players, eleven negotiation primitives, three negotiation phases and twenty eight negotiation states and their state transition diagrams. The proposed protocol shows its promising performance in terms of time for international trade negotiation successful rate, international trade negotiation utility and time for international trade negotiation.

Modeling of Energy-Saving Optimization Model by Sub-Sheet Dryness Coordination Based on Muti-Agent

Abstract: According to Multi-Agent network topology of the globe energy node in papermaking dryer section, the optimal algorithms of each part of sheet for energy consumption node Agent is designed through the mentality of designing. And multi-Agent contract net protocol is improved based on the gambling solution of mixed linear complementary problem. The overall steam saving optimization can be achieved by coordinated and local optimization and globe energy balance of each energy node for the four group of paper drying process.

An Extension to the Contract-Net Protocol Applied to the Transport Planning Problem of Oil Products

Abstract: In supply chains of petroleum industry, maintaining a proper inventory level for multiple petroleum products is a crucial issue. Basically, this chain has several elements like producer bases, consumer bases and terminals that are linked by means of a multi-modal transport network. These elements must cooperate to achieve the global goal of the system with a minimized cost. To achieve this goal, this paper presents a multiagent protocol for simultaneous negotiations based on the Contract-Net and the application of this in the chain aforementioned. As a result, this protocol proved to be very efficient to return a feasible solution in a low processing time.

Bidirectional selection cooperation approach based on Multi-Agent

Abstract: A bidirectional selection cooperation approach based on Multi-Agent is presented, in which some parameters, such as the ability value, communication costs and so on, are introduced into the classical contract net protocol. More importantly, the bidirectional selection mechanism between assign task agent and perform task agent is introduced into collaboration for the first time. These parameters reduce the communication consumption and balance the resource load among all Agents. The bidirectional selection cooperation increases cooperation efficiency and ensures the reliability and correctness of the whole Multi-Agent system. At last, taking detonator production schedule as an example, it proves that the bidirectional selection cooperation approach prolongs the system lifetime, improves the system load and increases the accomplished tasks in unit time.

Integrating Manufacturing Process Planning with Scheduling via Operation-Based Time-Extended Negotiation Protocols

Abstract: It is proposed in this paper the on-line adaptation of process plan with alternatives, through the application of an operation-based time-extended negotiation protocol for decision-making about real-time routing of job orders of parts composed of machining operations in a job-shop environment The protocol is modified from the contract net protocol to cater for the multiple tasks and many-to-many negotiations The grouping of the machining operations enables reduction of setup times, resulting from the reduction of machines changes For each part, all feasible routings are considered as alternative process plans, provided the different manufacturing times in each machine are taken into account The time-extended negotiation period allows the visualization of all of the times involved in the manufacture of each part, including those times that are not considered in systems of this nature, such as the negotiation times among agents Extensive experiments have been conducted in the system, and the performance measures, including routings, makespan and flow time, are compared with those obtained by the search technique based on the co-evolutionary algorithm
