Abstract

Bid and tender is the core stage in construction project, however, many evaluation factors can be handled easily by qualitative analysis, which is hard to avoid subjectivity. In this paper, a new evaluation index system is proposed to use quantitative analysis in order to avoid error which is induced by subjectivity, firstly. Secondly, an improved BP neural network is proposed as an evaluation method. The results indicated that the process of evaluation is simple and practical, and the accuracy can satisfy the actual requirement based on this new evaluation index system and the improved BP neural network.
