Abstract:

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.
