The Assessment Method of Supply Chain Risks Based on Vague Sets

摘要

In order to evaluate the supply chain risks, proposed the combination method based on Vague Sets and fuzzy risk assessment, and took an application model for example. First introduced the basic knowledge about fuzzy mathematics and Vague sets. Then gave the model of risk assessment and its algorithms, determined the major risk factors using Vague set theory and fuzzy mathematics method, combined the expert evaluation and fuzzy switch, applied the fuzzy analysis method to the static risk assessment of suppliers' risks and the individual risk status assessment of special event. Finally, described the specific flow by an example.
