Abstract


With the continuous development of the national economy and people's living standards increasing demand for electricity continued to increase grid annual investment is also growing , and the appraisal of investment returns become an important basis for grid enterprises to invest in management and decision-making . Investment benefit evaluation and assessment of the majority of enterprises are not comprehensive enough , and the lack of scientific theory , difficult to guarantee the authenticity of the results of the evaluation . The subject on the basis of grid investment benefit evaluation and examination process , combined with the number jurisprudence statistical methods to establish a complete investment efficiency evaluation model and its application to practice, Hebei Electric Power Company has developed a set of investment efficiency evaluation evaluation of the application system . System by building the investment benefit evaluation index system , complete the index value , the index weight calculation , and finally the appraisal results show the form of a score . Extended functionality of the system to achieve the index system makes the index system according to the needs the flexibility to change ; important degree of assurance of a reasonable evaluation index weight calculated by combining ; indicators trend superimposed comparative analysis easy for users to identify the interactions between the indicators factors ; improve the evaluation system management functionality of the system at all stages of the investment benefit evaluation category management ; monitoring data source is set to ensure that the integrity of the data sources used in the index calculation , powered residential settings makes in -depth analysis of some indicators analysis of a flexible range . The system uses B / S mode based on J2EE framework . The realization of the system is a combination of theoretical and practical results , is a combination of research work and enterprise technology innovation . The application of the system to promote a change in the investment philosophy of each power supply company , to optimize the investment structure , promotion of high value .
