Abstract: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.
