A methodological approach for modeling supply chain management

Modeling and managing Supply chain management systems that span multiple organizations involves new challenges, mainly regarding the ability to cope with change on the wide variety of languages and technologies which are heterogeneous in permanent evolution. The goal of our work is to contribute to the field of modeling and designing Supply chain management systems. Let´s put forward a methodological approach which is based on four aspects (resource aspect, organizational aspect, functional aspect and interaction aspect) and which uses the multi agents system to model their different actors. Each actor in the proposed model is represented by a subsystem. They interact with each other to accomplish their tasks using two types of interaction, internal and external. They can communicate, negotiate and collaborate through a communication interface in order to discuss and negotiate the stocks, make the system more responsive and reduce inventory carrying costs.
