An adaptive ontology-mediated approach to organize agent-based supply chain negotiation

Effective supply chain management (SCM) comprises activities involving the demand and supply of resources and services. One important aspect of SCM is that companies in the supply chain may have to make decisions which are conflicting with the other partners. Negotiation is an essential approach to solve transaction and scheduling problems among supply chain members. Multi-agent systems (MAS) are being increasingly used in SCM applications. The advances in agent technology have provided the potential of automating supply chain negotiations to alleviate human interactions. This paper proposes an ontology-mediated approach to organize the agent-based supply chain negotiation and equip the agents with sophisticated negotiation knowledge. Firstly, a generic agent negotiation scheme is developed involving the agent intelligence modules, the knowledge representation method and the interaction behaviors. Then, the negotiation knowledge is structured through the usage of ontology, which performs as a hierarchical architecture as well as a descriptive language. The relationships between negotiation ontology concepts are defined through SWRL inference rules. Through this method, agents´ negotiation behaviors will be more adaptive to various negotiation environments in accordance with different negotiation knowledge.
