Integrated Comprehensive Evaluation And Intelligent Decision Support System Of The Operating State Of Power Supply Enterprises

During the course of analyzing and evaluating complex large systems with large scale and complicated structure and many influence factors such as the system of power supply enterprises, the intrinsic character of this kind of system must be considered such as multi-layer, multi-factor (multi-object, multi-attribute), multi-phase. It is necessary for the solving of practical comprehensive evaluation problems to evaluate this kind of complex object systems used widely effectively and synthetically. It is just the start and stand of putting forward the study. The purpose of the study is to discuss a effective method of comprehensive evaluation which is combine qualitative analysis with quantitative analysis and to construct the intelligent system supporting the process of comprehensive evaluation by advanced computer integrated method and information-processing technique.The main study content in the paper are the formalization and modeling and reasoning solving of multi-person multi-layer multi-object comprehensive evaluation problem (M3CEP), neural networks comprehensive evaluation model, the design and realization and development of qualitative and quantitative integrated comprehensive evaluation intelligent decision support system (IEIDSS) and the development of intelligent decision support system of the operating state of power supply enterprises. The detailed study is as follows:As to the formalization of M3CEP, the concepts of ordered evaluation tree (OET) and the smallest ordered evaluation tree (SOET) are put forward and the solving of complex M3CEP is regarded as comprehensive evaluation and comprehensive process of every SOET of OET.All kinds of comprehensive evaluation methods are lucubrated. The confirmation method of integrated multi-object weigh coefficient is proposed. The comprehensive utilization and choice strategy of these methods are also presented.Neural networks are applied to comprehensive evaluation of M3CEP. Themodel of comprehensive evaluation based on combination networks is put forward which supplies gist for constructing the encyclopedical multi-expert system.The environment system where fuzzy comprehensive evaluation model and reasoning method, neural networks comprehensive evaluation model, interrelated data and information, knowledge and experience of evaluation expert group, computer and all kinds of advanced technique are integrated is studied in detail.In the end, intelligent comprehensive evaluation decision support system of the operating state of power supply enterprises developed with PowerBuilder is produced in detail.
