Sažetak
In this paper, AHP (analytical hierarchy process) methodology and weighted properties method have been compared and applied to the selection of optimum alternative of stock material and manufacturing process. Three alternatives (stock materials) for the manufacturing of work piece are evaluated: rod, plate and tube. Six criteria were defined: stock material costs, stock material preparation costs, manufacturing costs, as well as material availability and purchase possibility, machinability and total material utilization. It can be concluded that the criteria weights can be more precisely defined by the AHP methodology using the Saaty scale than using the digital logic method. However, subjectivity is playing a great role in both of methods. Subjectivity is included to the comparison of alternatives by the original AHP methodology, also. Contrary, by using weighted properties method there is no subjectivity concerned of alternatives because of dealing with transformed values of criteria. From the viewpoint of costs, the best alternative, calculated by both of methods is steel tube machining.
