Abstract: This paper addresses risk evaluation in traditional bidding for software projects, in which risk evaluation is prone to be limited to certain stage in the bidding process and is quite subjective. To solve this problem, based on project life cycle theory, entropy weight method and AHP method are adopted to confirm relatively weight of risk factors and risk in every stage of project life cycle, and fuzzy synthetic evaluation is used to synthetically evaluate the risk in the bidding for software projects. An example is given to indicate: the risk evaluation model formulated in this paper gets over the drawback of the subjective judge, and confirms the key fields to risk control in the whole and each stage of project life cycle. The model has well applicability, as well.
