Research on the Decision Model on Optimal Stopping of the Account Sale under Imperfect Information

The shaping of the buyer´s market and the increasingly throat-cutting competition both serve as the key reasons for the account sale being the essential selling means for enterprises, but what cannot be ignored is that fast and blind account sale not only brings without expected earnings, but also causes loss because of the defaults of the target companies. On the other hand, the disappearance of market opportunities at any time doesn´t permit the longer decision time for tally companies. Therefore, when confronted the account sale opportunity, it is meaningful to choose a correct decision at the right time for tally companies. In this paper, under information entropy and dynamic planning theory, the probability of contract-violated enterprises relevant to the tally company along with the disappearance probability of market opportunities would be fully taken into consideration, decision model on optimal stopping of the account sale under imperfect information has been established. Meanwhile, we conclude the decision rules in order to enhance the scientific probability and the accuracy of the decision.
