摘　　要：方案选择与评价是可行性研究阶段和招标投标阶段的重要环节,决定着软件项目的成败。针对软件项目方案难以评价的特点,文中运用灰色综合评价方法进行研究。首先,建立评价指标体系,包括评价指标体系模型、评价指标描述以及其他相关工作;接着,建立数学模型,包括确定评价指标、定性指标定量化、确定最优指标集、确定原始评价矩阵、规范化处理、确定评价矩阵、灰色综合评价等步骤;最后,给出了具体评价实例。结果表明,运用灰色系统理论对软件项目方案进行评价,可以扩大信息源,提高评价结果的可信度。Schemc selection and evaluation are the important part of feasibility study phase and tendering and bidding phase,determining th~ sUCCeSS ＇Or failure of a software project. For the characteristics that the software project program is difficult to evaluate,use gray com- prehensive, evaluation method to study. First, establish the evaluation index system, including evaluation index system model, evaluation index description and other related works. Then, establish a mathematical model,including determining evaluation index, quantifying qual- itative indea and determining the optimal index set and the original evaluation matrix, standardized processing,determining the evaluation matrix, gray comprehensive evaluation and other steps. Finally, show the specific evaluation instance. The results show that use gray sys- tem theory to evaluate the software project program, can expand information sources and improve the credibility of evaluation results.
