knowledge version． The properties of performance knowledge itself could be varied． It is one kind of the radical mode． And it is the important approach to improve functions and extend performance knowledge in the injection molding machines’configuration design． Product model evolvement of the injection molding machine Product model evolvement of the injection molding machine can be divided into three levels due to the injection molding machine performance knowledge， as shown in Levels of injection molding machine’s product model evolvement The first level is the description layer of injection molding machines’ performance knowledge． It could be maintained to a certain extent． The second level records models and former evolvement the product configuration history information based on the first level． The third level is a perfect design environment which contains the passing and variance of injection molding machines’ performance knowledge． The differences between two tools could be realized． And the products could be improved in any time. A structured and understandable method of describing product model evolvement is one of goals which we want to achieve． At present, the research on the product model evolvement mainly focuses on the first level． The passing and variance information of product model would not be considered． The newest product model would be used all the time． These parts of performance knowledge are neglected． In the practical injection molding machines’ configuration design, the passing and variance information of product model drive the product model to evolve directly because of all kinds of causations. In the process of product performa nce knowledge passing and variance， the product model could be evolved． And it is the upper layer evolvement also is kind of injection molding machines’ evolvement mode could record the process of product model and performance knowledge evolvement effectively and particularly， and it is shown in ． The part P4 evolving from V1 to V2 causes the ponent C1 to evolve from V1 to V2． And the product model PM evolves from V0 to V1 also． When the performance knowledge evolves， product model could use the newest performance knowledge to realize the product model evolvement． Evolvement of product model 4. Reuse of injection molding machines’ performance knowledge Definition of performance knowledge reuse The reuse of configuration design can be defined as “giving a former product instance, a customer’s requirements set and a new product model to obtain a new injection molding machine’s instance which could meet the customer’s requirements set.” A concept model of injection molding machine is shown as follows: Inputs: R: Injection molding machine’s instance results。 Md: Injection molding machine’s requirement model。 ReMd: Reuse model of injection molding machine’s performance knowledge。 F(R,R r): Restriction functions. Outputs: Rr: Result of injection molding machine’s performance knowledge reuse。 r1, r2 … rn: Operation series of tool ’s performance knowledge reuse. An d： Rr Md； Rr ReMd； Rr = (rl， r2 … rn)R。 Rr is the most optimized. “ ” means satisfaction. The conformation and application of F (R, Rr) are related to practical application domain. The former knowledge should be modified。
