Research And Application Of Investment Benefit Evaluation Model For Power Grid Enterprises Based On J2EE Frame

With the continuous development of the national economy and increasing living standards, the social power consumption need increases gradually, annual investment in the power grid is also increasing year by year, power grid investment benefit evaluation is an important basis for investment management and decisions in power grid enterprise. At present, investment benefit evaluation and assessment methods of most enterprises are not comprehensive enough and were devoid of scientific base of theory. It is difficult to guarantee the accuracy of evaluation results.This paper combining with mathematical statistics methods, established a complete investment benefit evaluation model based on the research of power grid investment benefit evaluation procedures of electric power enterprise. It has been applied to practice and developed an investment benefit evaluation and assessment application system. This system through the construction of investment benefit evaluation, accomplishes the indicators calculation and index weights calculation, and displayed final appraisal results with the scoring form to users. The system to realize the function of index system expansion makes the index system can change according to requirements. Combining with several methods of index weights calculation is the guarantee to reasonably evaluate importance of index. Tendency of index addition and correlation is convenient in helping users to analyses influential factors between indexes. Management of appraisal system improving the function of classification management in different stages of investment benefit evaluation. Setting the monitoring of data source ensure the integrity of data source when the system calculates the relevant indicators. Setting the area of power supply makes analytic range of some indexes more flexible in deep analysis. The system is based on the mode of B/S and J2EE frame.This system is an achievement result from the combination of theory and practice. is the combination of scientific research and technological innovation in an enterprise. System applications effectively promoted to change the investment philosophy of power companies and optimize the investment structure. It have higher promotion value.
