Abstract: To avoid the drawbacks of the sub-evaluation of electronic evaluation of bidding for construction projects,this paper establishes a lean bid evaluation model based on the theory of lean thinking.Firstly,according to the composition of the project standard of construction project,the index system of bid evaluation model is constructed.Then by applying the method of TOPSIS the bid quotation is evaluated synthetically and the winning bidder is selected.In the bid evaluation,the k-means cluster analysis is used to analyze the tender offer and the weighted average is obtained,and the result is compared with the tender control price to show the competition degree of each unit tender offer. Finally,an example is given to show the practicability and the effectiveness of the lean evaluation model.
