The Research of the Safety Level of Nations Special Equipment Based on Analytic Hierarchy Theory

Abstract

Keywords: safety level of special equipment, analytic hierarchy theory, comparison and analysis Abstract: The paper expounds the necessity of scientific and objective evaluating and comparing the safety level of special equipment. Through the introduction of analytic hierarchy theory, the paper establishes a comparative analysis model of the safety level of the special equipment, and establishes the price criterion of the model index, and ensures that the evaluation conclusion is scientific and accurate. In the engineering application, several typical countries and China are selected to compare and analyze the safety level of special equipment, and some problems need to be solved are obtained. preface The special equipment is defined as eight categories like boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, passenger transport, large recreational facilities and field (factory) special motor vehicles for its greater risk and close association to peoples life safety . With the continuous development of society, people pay much more attention to security of the safe operation of special equipment. For this purpose, State Administration of quality supervision and inspection set up the corresponding inspection agencies and regulatory organization to carry out supervision and inspection tasks of the special equipment, in order to ensure the safe operation of the equipment (1) . There is no precise evaluation model and theory available now to evaluate the relative safety level of China when compare to other countries, this restricts the development of China's special equipment safety level at some extent. For this purpose, the SSEI built a working group in particular to explore the proper evaluation method and establish a comparative analysis model, several countries, the economic and social development stage is relatively close to China , are selected as the China's comparative analysis object to make clear the development stage of the china's special equipment safety level. The future development direction of China's special equipment safety management was obtained.
