| Summary: | In conditions of limited commercial information on costs and rational costs, machines' efficiency and rational parameters at the stage of their manufacturing can be established based on an analysis of technical and operational indices. On this basis, the technical efficiency of the machine can be established. The corresponding technical and operational indices are calculated based on known technical parameters and operating conditions of the machine. These are such indices as specific energy consumption (kVt∙h/m3), material consumption (t∙h/m3), productivity (m3/h), output per worker (m3/w∙h), and several generalized indices derived from the indicated ones. The choice of a rational solution is based on single-criteria optimization (on the one-criterion analysis).
