Research of Performance Evaluation of Power Generation Enterprises Based on Rough Set Theory

With the further reformation of electric power market in China, the competition is first inducted into the electricity generation. Putting on the net according to the price makes the evaluation of the electricity-generating enterprises' performance is becoming a hot topic nowadays. Rough set theory is a new kind of mathematical tool dealing with the problems of indefinite, incompatibility data and imprecise questions. This paper based on the rough set theory does the research on the application on the evaluation system of electricity-generating enterprises' performance. Based on the data mining methods of rough set theory and the heuristic arithmetic dedicates to find out the simplest evaluation rules of electricity-generating enterprises' performance.
