摘      要：By using attributes core and indiscernibility relation in rough sets, attributes reduction algorithm is given,expert knowledge system is simplified, the minimal set of effective rules is acquired, and a fuzzy Petri net is built. The Petri net can effectively decrease the complexity of the net structure. The algorithm proposed can be used to fuzzy reasoning by using a fuzzy Petri net,and an example illustrates the efficiency of combining rough sets and fuzzy Petri net.
