十 序贯决策在带有观测的决策问题中,所谓序贯决策是指决策需要的观测是逐次进行的,并给出停止观测的规则,即每进行一次观测,决策者从观测中所得到的有关信息,对照观测的停止规则,决定是否停止观测。若满足停止观测规则,则立即仃止观测,并从已做过的观测中所获得的信息做出决策;若不满足仃止观测规则,将继续观测,直到满足仃止观测规则为止。这样抽样方法叫序贯抽样,依序贯抽样做决策就是序贯决策。 Ten Sequential Decisions In the case of decision-making with observations, the so-called sequential decision-making means that the observations needed for decision-making are performed sequentially and the rules for stopping the observation are given, that is, for each observation that the decision makers derive from the observations Related information, control the observation of the stop rules, decide whether to stop the observation. If the stop observation rules are satisfied, the observation will be stopped immediately and the information obtained from the observations already made will be used to make the decision. If the observation rules are not satisfied, the observation will continue until the observation rules are satisfied. This sampling method is called sequential sampling, sequential sampling decisions are sequential decision-making.
