摘要
目标建模是早期信息系统需求分析的关键技术.针对企业高层目标难以评估的问题,提出一种企业目标量化建模方法,以证据理论作为逻辑基础,对企业目标可满足性进行定量表征,借助Dempster证据合成法则,设计多目标贡献关系合算法,通过实验验证方法的有效性.
Evidence Theory used in calculating the uncertain metrics of the uncertain events is developed based on probability theory. And the organization goals describe the future states of an enterprise during some time so that the possibility of one goal satisfied is evaluated with some uncertainty which is accorded with the uncertain evaluating method in evidence theory. In this article, evidence theory is employed to formulate the organization goals and to define a reasoning method with goals. With goal model built reasoning is done according to the automatic reasoning algorithm in which only uncertain metric of some goals is needed.
