Abstract—In this paper the investigated problem is how to choose assembly technology for particular mechanical device. The selection process is performed by application of optimization strategies in the presence of uncertainties and discreet number of alternative assembly technologies. Six strategies with proposed new optimization criterion are presented and discussed. In this paper, as a main optimization criterion, it is proposed to minimize the combined cost of labour and equipment (with respect to a single manufactured product). In addition to those strategies, in this paper, three new and modified strategies are proposed, which involve certain social aspects in the decision making process. The problem solution is demonstrated on a particular manufacturing problem - assemble of a mechanical device (hydraulic gear pump).
Index Terms—Optimization strategies, uncertainties, decision making, assembly technology selection.
