RISK EVALUATION MODEL OF SUPPLY CHAIN SYSTEM BASED ON UNASCERTAINED THEORY

摘要

Supply chain systems have complex and opened characteristics, the system risk is always subjected to the comprehensive effect of external factors and internal factors, which determined the great uncertain characteristic of supply chain systems risk. Based on this, this paper constructed index sets for supply chain risk assessment from the system perspective, and with the combination of expert evaluating and unascertained information processing theory, built a supply chain system risk unascertained-evaluation model, and designed application to validate the risk evaluation model, results show that evaluation model designed in this paper has a good predict effect for the supply chain system risk evaluation, and has a high operability and usability.
