Study on the model of collaboration trust in supply chain based on ontology

Collaboration relation among companies in supply chain is facing serious challenges because of partners´ opportunism and demoralization. Therefore, collaboration trust in supply chain is viewed as a central problem for discussion. The paper puts forward a framework of collaboration trust in supply chain based on ontology including: Primitive Information Layer, Information filtration Layer, Trust Ontology Layer, Ontology Query Layer and Application and Explanation Layer; and designs the domain ontology in trust and the other four sub-domains: enterprise trust ontology, product trust ontology, service trust ontology and information trust ontology. The three-level model comprehensively analyses the trust in the supply chain from four aspects, providing scientific and rational proposals for the cultivation, development and stability of collaboration trust in supply chain to promote stable development of supply chain relationships.
