Seeing the critical safety conditions due to hazardous goods warehouse and the current dissatisfactory evaluation system, this paper aims to make an investigation on the warehouse operations of hazardous goods by illustrating the storehouse selection criteria and propose a storeroom selection model. To achieve our goal, we have first of all, made a thorough study of the storehouse supervision and control regulations and the practical working experience so as to create an evaluation index framework of the selection according to the fuzzy optimization with our analysis of the factors focusing the process of storehouse selection. To be sure, the evaluation index framework includes the storeroom capacity, the kind of storage facilities, the cost involving the goods storage, temperature and humidity, the condition of transportation, and so on. Secondly, we have worked out the weight of each element, having defined and arranged each dimension and factor in terms of their respective importance in regard to the connection between the subjectivity and objectivity of the storage business and confirming the weight of index by improved entropy weight method. And, last of all, we have established an optimized storehouse model by means of fuzzy comprehensive assessment. Via providing useful suggestions on how to use the evaluation index and the optimized model, we have tried to adopt our model to evaluate five pre-selected electric detonators'storehouses of such goods. The follow -up exploration and engineering application prove that the optimization model is useful for the storehouse selection and the grades of pre-selected storehouses can be classified and examined comprehensively by the results of the actual use. Besides, storeroom capacity, the kind of storage facilities, the cost charged for keeping such goods, temperature and humidity should also be included into the most important items for carrying out such warehouse safety evaluation with the purpose of practical management.
