Productivity as Measure of Multiproduct Metal Processing Production Efficiency

Modern metal processing machine building production is multiproduct. Manufacturing resources of the enterprises are usually limited and their cost constantly grows. It is essential to enhance production effectiveness as its possibility to successfully solve production tasks that are constantly changing and becoming more complex due to efficient use is now limited. One of the main parameters determining production efficiency is productivity. There are no a single opinion and methodical approaches to efficiency evaluating in the environment of the multiproduct production. Traditionally, productivity is considered only as a measure of efficiency of the timing budget use of the equipment being a part of the production system. The present research demonstrates the necessity to understand productivity as efficiency criteria for use of manufacturing resources of all types, as well as include correspondences for evaluating it. We've performed the analysis of main approaches for enhancing of the exploited equipment productivity. Enhancement of the structural-and-parameter features of the performed process operations is the main reserve of productivity increasing. Research results can be useful for improving methods of technological designing during preparation of metal processing production. (C) 2016 The Authors. Published by Elsevier Ltd.
