Safety Evaluation Of Special Equipment

Special equipment is a kind of important and basic equipment for national economic construction and a kind of vital infrastructure closely related to people's daily life, it can benefits mankind, but can also cause great losses to people's life and property in the situation of mismanagement. Meantime, as the demand of safety, health and environment increases, special equipment safety is being more and more concerned. How to improve special equipment safety by establishing special equipment safety evaluation system has become a very valuable issue.Because special equipment safety evaluation is still in its primary stage of exploration in China, the paper studies the problems about how to establish the evaluation index system of special equipment and choose a suitable evaluation method for special equipment based on the present development and practice of domestic and overseas special equipment safety. The main content is:1. Introduces the history of special equipment safety management in china, details the research development of domestic and overseas safety evaluation and special equipment safety evaluation, and points out the problems that exist in china's special equipment safety evaluation, finally indicates the purpose and meaning of the paper.2. After analyzing the safety characteristics, accident features and reasons of accident of special equipment and combining with other literature and expert experience, establishes the safety evaluation index system of special equipment, then calculates the weight of each index by using Analytic Hierarchy Process, thereby laying the foundation for the following evaluation.3. Introduces several kinds of common safety evaluation methods and indicates the advantages and disadvantages of every method, then chooses the Fuzzy Comprehensive Evaluation Method to evaluate special equipment safety. After that, the safety evaluation method is used in a case study, and the evaluation result is analyzed by safety grade characteristic quantity. The case study indicates that the established safety evaluation index system of special equipment and the chosen evaluation method both have good feasibility and applicability.
