Multi-objective Tree Analysis Of The Performance Evaluation Of Sewage Treatment Plant

This paper use the multi-objective tree analysis to build a sewage treatment plant construction project performance evaluation index system. Sewage treatment plant on the selection of performance evaluation, from which sum up to the sewage treatment plant investment, construction, operation, effect all aspects of performance factors, and use that funding, construction, regulatory processes, the actual content of Design and Construction After the implementation and actual operations to achieve the effect of such an important factor. Judged by experts in data reliability, validity analysis to determine the performance evaluation of sewage treatment plant "input, process, output, effect," four dimensions, nine-level indicators,23 secondary indicators and their subordinate The primary target.Through the questionnaire method and AHP to affect the performance of a sewage treatment plant, two factors were analyzed and calculated weights to determine the target relative to the same level on an indicator of relative importance and weights. The use of multi-objective indicators of tree model and relationships between, and to determine the merging algorithms, merge to achieve the quantitative performance evaluation calculation, the calculated value of the performance of the integrated wastewater treatment plant shall be satisfactory degree, in order to determine their final assessment grade.This paper the theoretical basis of the study, using Visual C++6.0 programming language to be relatively complex evaluation of calculation tools software quick and easy calculations completed, the better to achieve a sewage treatment plant performance evaluation of data input, saving; achieved background on the background levels of indicator calculation; achieve real-time error data modification function; achieved and the part of the independent evaluation of the overall evaluation of the results report generation. Generation software platform to enable performance evaluation of sewage treatment plant into a computer by a manual operation, so the quality and efficiency improved significantly.This study established the evaluation system from the systemic and adaptability is better than the previous evaluation system. The establishment of the software platform to enhance the efficiency of actual operation. Thesis in time to discover not only exist in the whole process of performance and results, but also the future of investment projects on strict control, and provide a strong basis for government decision-making, and performance evaluation of sewage treatment plants to make the pilot promotion contribution.
