【摘要】 通过将软件开发过程分解为分析、设计、实施阶段 ,根据决策者对每一阶段的技术风险、费用风险、进度风险的确信度 ,给出了一种基于 Dempster- Shafer证据组合理论的风险评估方法。从而 ,将软件开发过程中影响风险的多种不确定性定性指标转化为确定的定量指标进行评价。最后通过实例说明了该方法的有效性。更多还原

【Abstract】 Based on Dempster-Shafer’s evidence theory, an evaluation of risk used to evaluate the risks of software development is proposed. This method is obtained through decomposing the process of software development into analyses, design and implement as well, and decision maker’s degree of trust about the technology risk, cost risk,advance risk of every stage. By using this method to fuse the uncertain multiattributes affecting the risk of software development, the risk evaluation problem is converted into a difinite multiple attributes evaluation problem. Finally, an example demonstrates the validity of this method.更多还原
