Generally, a part may go through multiple setups and a single setup may machine multiple parts. Hence, both inter-setup and intra-setup feature relationships affect the manufacturing cost. IT grades relationships are also considered in the cost model at part level. For example, it is cost effective to have different IT grades assigned to same type of feature produced by a single process. These relationships and their effects are evaluated by a relationship factor. Table VI shows some relationship factor examples used in this study. After applying relationship factors to feature costs, the part level cost are formulated.
