鉴于决策主体的主观偏好对策略选择的重要影响,设计主体偏好视角下面向复用的应急策略评价指标体系,并采用分步评价法对策略进行具体评价。首先,从定性的角度基于评价主体自身对客观条件的判断进行限制条件的评价;其次,通过主体对损失、成本、形象、时间性和风险指标重要程度的判断,利用相对比较法确定主体的主观偏好排序,作为策略执行效果指标加权的依据;再次,计算策略执行效果各项指标的加权得分,根据得分推荐策略。
In view of the important influence of the subjective preferences of decision-makers on the selection of tactics, the evaluation index system of emergency strategies for the reuse is designed from the perspective of the subject preferences, and the method of step-by-step evaluation is used to evaluate the strategies.
