摘要:

当关于不确定性的信息不能以简单的概率方式量化时,可能性决策理论的主题通常是一个自然的考虑。可能性决策理论的发展产生了一系列的可能性准则,如悲观可能性定性效用、可能性似然占优、二元可能性效用和可能性Choquet积分。本文主要研究可能性决策树中的序贯决策问题。它提出了一个复杂的问题,找到一个最佳的策略,根据单调性的优化标准,它允许应用动态规划,提供了一个多时间减少的决策问题的研究。它还表明,可能性Choquet积分不满足这一性质,在这种情况下,优化问题是NP -困难的。

英文摘要:

When the information about uncertainty cannot be quantified in a simple, probabilistic way, the topic of possibilistic decision theory is often a natural one to consider. The development of possibilistic decision theory has lead to a series of possibilistic criteria, e.g pessimistic possibilistic qualitative utility, possibilistic likely dominance, binary possibilistic utility and possibilistic Choquet integrals. This paper focuses on sequential decision making in possibilistic decision trees. It proposes a complexity study of the problem of finding an optimal strategy depending on the monotonicity property of the optimization criteria which allows the application of dynamic programming that offers a polytime reduction of the decision problem. It also shows that possibilistic Choquet integrals do not satisfy this property, and that in this case the optimization problem is NP - hard.
