Decision support for machine tools selection in process planning and equipment investment

The paper considers two cases of machine tools selection: machine tools selection as part of equipment investment and machine tools selection in defining technological process planning. The paper presents the issue of decision making using the Analytic Hierarchy Process (AHP) method. The application of the AHP method in solving multiple criteria decision making is illustrated through a practical example using the Expert Choice (EC) software. Selection of criteria, their significance and level of hierarchy are very important. In the considered case a machine tool is being selected from the range of machines existing in a smaller-sized production plant on the basis of a representative product. Some of the most commonly used criteria when choosing a machine tool include the following: production quantity, machining type, geometrical features of the machine, complexity of the workpiece, productivity etc. In case of machine tool selection as part of equipment investment a set of additional criteria related to the economic field need to be considered. These criteria are related to the price of machine tool, guarantee period, etc. We will elaborate some scenarios for both considered cases as part of decision support. The finally obtained results for both cases will be analysed and compared
