Description

Technical Field

[0001] The present invention belongs to the technical field of data processing, and in particular relates to a comprehensive bid evaluation method based on an entropy weight method. Background Art

[0002] There are many forms of enterprise material procurement, such as direct designated unit ordering, inquiry procurement, competitive procurement, bidding, etc. The use of bidding to purchase equipment and other materials can better reflect the fairness, openness and impartiality of the procurement process, and is more conducive to the purchase of high-quality, low-cost and high-quality products by the material users, and obtain more long-term and high-quality services. In the bidding work, bid evaluation and bid determination are the key links that play a decisive role. The bid evaluation method is the basis and basis for bid evaluation and bid determination. The bid evaluation committee will evaluate the bids based on the bid evaluation method, determine the pros and cons of each bidder, and then determine the final successful bidder. The bid evaluation method is the basis and judgment for the bidder to prepare the bid document, and is the basis for whether the bid evaluation is fair and reasonable.

[0003] According to the explanation of the basic principles of information theory, information is a measure of the degree of order of a system, and entropy is a measure of the degree of disorder of a system; according to the definition of information entropy, for a certain indicator, the entropy value can be used to judge the degree of dispersion of a certain indicator. The smaller the information entropy value, the greater the degree of dispersion of the indicator, and the greater the influence of the indicator on the comprehensive evaluation (i.e., weight). If the values ​​of a certain indicator are all equal, the indicator will not work in the comprehensive evaluation. Therefore, the information entropy tool can be used to calculate the weight of each indicator to provide a basis for the comprehensive evaluation of multiple indicators. Therefore, the bid can be evaluated based on the entropy weight method, but the existing bid evaluation method is not comprehensive enough, and the data processing ability is not accurate enough, which makes the evaluation conclusion unconvincing.

[0004] Therefore, the existing bid evaluation methods cannot meet the needs of actual use, so the market is in urgent need of improved technologies to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a comprehensive bid evaluation method based on the entropy weight method, in which the entropy weight method is used to determine the weight of each evaluation indicator, the entropy weight method is used again to determine the weight of each influencing factor of each evaluation indicator itself, and the entropy weight method is used again to determine the weight of each bid evaluation personnel. The three-level entropy weight method is used for processing, and the bids that meet the composite requirements can be basically obtained, which solves the problems of insufficient accuracy and large errors in the existing bid evaluation methods.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a comprehensive bid evaluation method based on entropy weight method, comprising the following steps: S1: Based on the field of the tender, determine the evaluation indicators used to evaluate the tender level; the evaluation indicators include price indicators, technical indicators, enterprise indicators and after-sales service indicators; S2: Use the entropy weight method to calculate the weights corresponding to each evaluation index; S3: Classify each evaluation indicator again, determine the influencing factors of each evaluation indicator, and collect historical data of each influencing factor of each evaluation indicator; S4: Use the entropy weight method to calculate the corresponding weight of each influencing factor in the evaluation index; S5: Collect the historical bid evaluation data of each bid evaluation personnel and process the historical bid evaluation data; S6: Use the entropy weight method to calculate the weight corresponding to each bid evaluation personnel; S7: Conduct a comprehensive evaluation based on the weight of each evaluation indicator, the weight of each influencing factor and the weight of the evaluator.

[0009] Furthermore, the enterprise's own indicators in S3 include financial status influencing factors, reputation influencing factors and performance influencing factors; and the entropy weight method is used to calculate the corresponding weights of financial status influencing factors, reputation influencing factors and performance influencing factors in the enterprise's own indicators.

[0010] Furthermore, the after-sales service indicators in S3 include training plan influencing factors, response time influencing factors and local permanent office influencing factors; and the entropy weight method is used to calculate the corresponding weights of the training plan influencing factors, response time influencing factors and local permanent office influencing factors in the after-sales service indicators.

[0011] Furthermore, the historical bid evaluation data of each bid evaluation personnel in S5 are arranged according to time, and based on the distance in time, the historical bid evaluation data are divided into several segments, and then the weight of each segment is calculated based on the entropy weight method, and the average historical bid evaluation data of the bid evaluation personnel is calculated.

[0012] The present invention has the following beneficial effects: The present invention adopts the entropy weight method to determine the weights of various evaluation indicators to obtain the final evaluation results of the bid. The entropy weight method can deeply reflect the distinguishing ability of the indicators, determine better weights, and make the weighting more objective, comprehensive, theoretically based, and more credible.

[0013] The present invention uses the entropy weight method to determine the weights of various influencing factors of each evaluation index itself, thereby ensuring the accuracy of the scores of each evaluation index.

[0014] The present invention uses the entropy weight method to determine the weight of each bid evaluator again, thereby ensuring that excellent bid evaluators account for a larger proportion, further eliminating subjective influences, and further improving accuracy.
