中文摘要：

传统软件项目投标的风险评估往往局限在投标过程的某个阶段，且评估具有较强的主观性。针对此问题，论文基于项目生命周期理论。采用熵权系数法和AHP方法来确定各个风险因素和项目生命周期各阶段风险的相对权值，利用模糊综合评判法对软件项目投标的风险进行综合评估。实例分析表明：所建立的风险评估模型克服了主观判断的弊端，使投标者明确整个项目生命周期及生命周期各阶段的风险控制的重点领域，具有良好的适用性。

英文摘要：

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.
