Emergency Logistics Channel Selection Decision Based on Rough Sets Theory and Extension Model

On the basis of analyzing the factors that affect emergency logistics channel selection decisions, this paper builds the evaluation index system for just such events. This paper also builds a comprehensive evaluation method based on rough set theory and improved extension theory, by which we can get the emergency logistics channel selection decision sequence and the reliability level of all of the alternative emergency logistics corridors. Finally, the paper verifies the viability of the evaluation method through case study. This paper expands the application field of the extenics theory, changes the traditional method for emergency logistics channel selection decisions, and provides new thoughts and methods for emergency logistics channel selection decisions.
