When re-using used parts, their quality needs to be evaluated based on their usage history data, since used parts may have changed their size and accuracy due to deterioration such as abrasion and deformation during their former use. In order to construct a computer aided recycling manufacturing system, this evaluation process should be supported from the product information processing. As results of this research, the structure of the product model and the new evaluation procedure were provided.Form tolerances are defined for each geometric element. A geometrical-relation constraint is defined for the geometrical relation between geometric elements. Functional constraints for satisfying the product function are defined as the geometrical accuracies of assembly relations, motion trajectory and so on. Corresponding to each functional constraint, a behavior-mechanism relation table is generated from the product model. In the preparation stage of the evaluation, each set of deteriorated status given by the behavior-mechanism relation table is tried with the behavior simulation. In the behavior simulation, the value of the corresponding geometrical-relation constraint in the movable element is interpreted as a dimension of the clearance between parts. By superimposing the result of behavior simulation, the effect of that set of deteriorated status on the behavior can be calculated as the value of the corresponding evaluated geometrical accuracy. For the evaluation, the product behavior at the usage stage is compared with the threshold value of each functional constraint in the behavior-mechanism relation table. If a functional constraint to be achieved is found to be satisfied, the behavior-mechanism relation table corresponding to the functional requirement can be utilized for predicting the deteriorated status of the related movable elements. Using this methodology, the deteriorated status for each movable element is estimated.

在重复使用旧零件时，需要根据其使用历史数据评估其质量，因为旧零件在以前的使用过程中可能会因磨损和变形等劣化而改变其尺寸和精度。为了构建计算机辅助回收制造系统，该评价过程应从产品信息处理中得到支持。根据研究结果，给出了产品模型的结构和新的评价方法。为每个几何元素定义形状公差。对几何元素之间的几何关系定义了几何关系约束。满足积函数的功能约束定义为装配关系的几何精度、运动轨迹等。针对每个功能约束，从产品模型中生成一个行为-机制关系表。在评价的准备阶段，对行为-机制关系表给出的每一组劣化状态进行行为模拟。在行为仿真中，将可动元件中相应的几何关系约束的值解释为零件间间隙的一个尺寸。通过对行为仿真结果的叠加，可以计算出该劣化状态组对行为的影响，即相应的评估几何精度值。为了进行评价，将产品在使用阶段的行为与行为-机制关系表中各功能约束的阈值进行比较。如果满足所要达到的功能约束，就可以利用与功能需求相对应的行为机制关系表来预测相关活动元件的劣化状态。利用该方法，对每个可动构件的劣化状态进行了估计。
