Pdownrank the lower Wilson confidence interval limit of the initial score for the contractor; z represents the statistical constant of Z corresponding to a confidence level of 1-alpha, typically 95%,the statistical constant Z is 1.96; n is the total number of projects undertaken by a contractor in the last R years.
7. The system of claim 1, wherein the system comprises: the final evaluation result is divided into four grades by adopting a percentage system, the A-grade mapping interval is 90-100 grades, the B-grade mapping interval is 80-90 grades, the C-grade mapping interval is 70-80 grades, the D-grade mapping interval is below 70 grades, and the linear function mapping interpolation calculation formula is as follows:
in the formula:
Rigrading a percentage score for a certain contractor; u shapeminMaking a minimum value between the partitions for the percentage to which the corresponding correction grade belongs; pdowniA corrected score value corresponding to a certain contractor; pdownminThe minimum value of the corrected score values of all the contractors in the corresponding correction grade is obtained; u shapemaxObtaining the maximum value among the partitions for the percentage of the corresponding correction grade; pdownmaxThe maximum value of the revised score values for all contractors within the corresponding revision level.
8. The system of claim 1, wherein the system comprises: the performance information comprises the contractor personnel credibility, the contractor historical project completion condition information, the contractor historical project completion quality information and the contractor historical project completion satisfaction information.
9. The system of claim 1, wherein the system comprises: and the design and construction unit uploads the information of the engineering project which is already performed by the design and construction supervision contractor to the historical database unit.
10. The system of claim 1, wherein the system comprises: and the output form of the final evaluation result is in a sector graph form, a bar graph form or an Excel table form.
