摘　　要：针对因决策因素个数的减少而导致的决策精度降低的情况,提出了一种基于单向变异S-概率粗集的动态决策方法。利用单向变异S-概率粗集的属性动态迁移特性,结合知识库中的统计信息,讨论了单向变异S-概率粗集模型的属性概率性质。利用上述性质的讨论,给出了一个具体的军事动态决策实例,从而证明该方法可以有效地提高决策精度。With the reducing of decision factors,decision precision is low.A method of dynamic decision based on one direction variation S-probability rough sets is put forward.And taking the attribute＇s dynamic transfer property of one direction variation S-probability rough sets and statistical information in knowledge base,the attribute＇s properties characters of one direction variation S-probability rough sets are discussed.Using the above property discussion,a special military application example is given,which proves this method is effective in enhancing decision accuracy.
