Research On Evaluation Method Of Bidding Process In Electric Power Enterprises

An important guarantee for the safe and stable operation of power grid is the safety and reliability of power equipment.At present,the procurement of power materials in power enterprises is generally carried out by bidding.The most important link in the overall bidding activities is the bidding evaluation,which is directly related to the final results of bidding activities and affects the overall quality of power enterprise construction.With the continuous development of the times,the construction of power facilities is increasing,and the number of suppliers is also growing rapidly,which leads to the completion of supplier performance has become another factor affecting the overall progress and quality of power enterprise construction.It is of great significance to consider supplier performance in the evaluation system of power equipment to ensure the safety and stability of power grid.This thesis focuses on the bidding evaluation methods in bidding activities,summarizes the influencing factors of bidding evaluation,and combines the bidding process with the supply process to conduct the overall evaluation of the bidding power equipment.The supplier performance evaluation indicator is added to the evaluation indicator system of power equipment bidding.It strives to avoid the possible problems in the back-end supply of power equipment during the front-end bidding activities,and selects suppliers more suitable for the specific equipment of power engineering construction for power enterprises.This thesis takes distribution transformer,a representative material category of power equipment with complex structure,as an example for analysis.A scoring indicator system is established,which consists of 4 first-level indicators of technology,commerce,price and supplier performance,and 11 second-level indicators and 31 third-level indicators.From the perspective of the actual engineering needs of power construction projects,the particularity of power equipment and the stability of operation,four indicators are selected for the supplier performance evaluation part and put into the scoring indicator system for comprehensive consideration.In the calculation of the comprehensive weight of the overall model of the evaluation indicator,the method of combining the fuzzy analytic hierarchy process and the entropy weight method is adopted.The first-level indicator and the second-level indicator cannot be quantitatively analyzed.The fuzzy analytic hierarchy process is used to determine the indicator weight,and the entropy weight method is used to determine the indicator weight of the third-level indicator,so that the weight allocation is more scientific and reasonable.In the calculation of the evaluation results of the overall evaluation system,in order to reduce the influence of human factors on the evaluation results,to prevent the reviewers from affecting the accuracy of the evaluation due to the secondary scoring of the data.The original data of quantitative indicators are retained,and the grey correlation analysis method and TOPSIS method are used to evaluate the overall data.In the example verification,the results of the confirmed winning bidder are analyzed and compared.The evaluation results show that the introduction of supplier performance evaluation into the traditional bidding evaluation system of electric power enterprises,as well as the comprehensive weight and evaluation result calculation method of the built bidding evaluation system are more in line with the actual needs of electric power equipment bidding and procurement,and can play a positive role in the bidding and procurement of electric power materials.
