本文提出了一种改进的决策试验与评估实验室（DEMATEL），称为随机DEMATEL，用于提取复杂问题的结构模型，并在考虑结构不确定性的情况下表示每个因素的优先级。在随机DEMATEL中，结构的不确定性表示为随机模型。通过数值实验和实验分析得出：当结构不确定时，随机DEMATEL可以通过调度影响程度和中心作用程度提取结构特征；随机综合重要性可以表达优先级的不确定性，并考虑决策者的态度来确定优先级；悲观、中立或乐观。
In this paper we propose a revised Decision Making Trial and Evaluation Laboratory (DEMATEL), called stochastic DEMATEL, to extract structural model of a complex problematique and to represent the priority of each factor taking into account the uncertainty of structure. In the stochastic DEMATEL, the uncertainty of structure is expressed as a stochastic model. From numerical experiments and experimental analyses, the following results are obtained: when the structure is uncertain, stochastic DEMATEL could extract the features of structure by the degree of dispatching influences and the degree of central role; stochastic composite importance could express the uncertainty of priority and decide the priority taking into account the attitude of the decision maker; pessimistic, neutral or optimistic.
