Abstract
The aim of this article is to show the advantages that the use of a multiagent model can provide in implementing vertical and lateral coordination among the components of a noncentralized distribution chain. This model has been implemented in Java language in order to allow for the development of a Web-based decision support system that can perform the coordination strategies, simulated in this article in a real logistics chain.
This article, after introducing the main concepts related to the adoption of coordination mechanisms within a supply chain, the main issues of agent-oriented technology, and a brief review of the related literature, presents the structure of the proposed model and the static and dynamic behaviors of the decision-making agents. The design issues of specific coordination models, the negotiation mechanisms introduced, and their proper tuning are then discussed. The models have been applied to a real two-level distribution system of an electromechanical company, made up of a supplier and a geographically distributed network of retailers. Experimental results showed the benefits derived from the adoption of coordination-based models, above all in supply contexts, characterized by relevant information sharing among the main tiers of the chain.
