Unascertained Theory-based Power Supply Enterprise Security Research And Application

Electric power industry is the basic and important industry in national economy,which provides the basic guarantee to keep the industrial economy's robust running and stable development.Safety management is a fundamental and essential task in power supply enterprises.It is the prerequisite to fulfill safety management including makingsafety evaluation and finding out the current safety management situation completely.In this thesis,the power supply enterprises'safety evaluation indexes,factors right,and evaluation methods are studied in order to solve the problems of safety evaluation in power supply enterprises.The production system in power supply enterprises is a complicated human-machine-environment one with multi-factor,rmulti-variable,and multi-level. Therefore its safety evaluation involves a lot of uncertain information. On the basis of analysis about the advantages and disadvantages of random information,fuzzy information,and unascertained information,this paper utilizes unascertained mathematics theory and applies unascertained information and measure evaluation into the safety evaluation in power supply enterprises.Also,according to practical experience on the scene,this paper draws up a new view about safety comprehensive evaluation in power supply enterprises,namely,it combines unascertained measurewith the theory of even value of blind number.Besides,the safety degree of power supply enterprises is determined by analyzing comprehensively power supply enterprises safety level.During the comprehensive analysis utilizing method of unascertained measure evaluation,the most important thing are the establishment of evaluation element system and balance of various elements.The safety evaluation indexes systemof power supply enterprises is reconstructed by catching up with the academic foreland research andutilizing safety system engineering theory.A more comprehensive and scientific new evaluation system is found in this way. AHP method has been applied to determine the right of all factors of safety evaluation indexes system in power supply enterprises.What is more,the unascertained measure model of comprehensive safety evaluation in power supply enterprises is established and safety elements are degraded. On the basis of expert credibility,this paper studies MABM method compounded by uncertainty conclusion.Finally,a case study in ZouCheng Power Supply Enterprise that the new evaluation system adapts to the power supply enterprise successfully;moreover, the problems of power supply enterprise's safety system was found and the optimized proposal was presented based on this new evaluation system.
