As to the difficulty of spare parts varieties determination,some common methods are introduced. The factors (including importance,vulnerability,economies,replacement and obtain hardness)which are relevant to selecting spare parts varieties are analyzed. According to the method of the rough attribute reduction and attribute value reduction,the simplified spare parts varieties selecting rules are extracted from the rough set decision table. The adaptability of the method is verified through a case study. The results demonstrate the strong operability and easy implementation characteristics of the proposed method. The practical analysis method is proposed for equipment spare parts varieties determination.
