The Selection of Raw Materials in Process Planning System

Preparation process in single production is very dynamic so the goal is increasing of flexibility of production preparation, and decreasing of costs and time through the applying of Computer Aided Process Planning (CAPP system). Meanwhile, CAPP system very rarely has modules for raw material selection, so the paper presents criterions for such a kind of selection. These criterions present base for evaluation model which will improve process planning in CAPP system.
