Abstract
Because of burstiness, weak economy, time-uncertain of emergency logistics system, the paper constructs the operation model and its evaluation index system for emergency logistics system. In view of the imperfection of subjective determining index weight method in traditional evaluation, the index weight coefficients are determined by information entropy method of combining subjective judgment with objective evaluation. Then the fuzzy clustering and information entropy to determine the weights are used into emergency logistics system reliability evaluation. Finally the paper obtains a specific solution steps based on an example.

1.Introduction
Due to all kinds of the frequent occurrence of emergencies, such as natural disasters accidents, public health incidents and social security, increasingly acute disasters, it has become a huge risk to build a harmonious society and sustainable development. These emergencies cause a huge demand for emergency resources. How to plan, manage and control the flow of these resources, and quickly realize the timely, accurate, safe arrival of relief supplies and equipment, emergency logistics system reliability problem becomes particularly important[1-3].Currently, it has also been less for emergency logistics system reliability literature in home and abroad, and most research literatures mainly from the perspective of supply chain. For example, Luton agreed that the supply chain reliability mainly refers to the inventory
