Multi-operation Optimization of Responsive Manufacturing System with Energy Objectives by Taguchi Loss Function

Abstract

In a manufacturing unit generally more than one product is made in certain cycle time, and in order to become competitive, the progressive firms run the production facilities optima

lly. The customer also wants an optimum solution for their requirements. The energy cost constitutes a major portion of manufacturing cost. In current situation the manufacturing must be responsive to customer, vender, share-holder and all types of competition. The manufacturing must be flexible, easy to operate and mistake-proof, this is a robust organization. The ecosystem regulation and equilibrium guide us to control variability of production system also.

By this paper a methodology will be develop for batch manufacturing organization to work as responsive manufacturing system with energy considerations. The steel, chemical and pharmaceuticals unit follow batch type of production, because of low volume, high value products. Now the industries, all over the world, whether large or small, are facing challenges on multiple fronts, competition is becoming borderless, new alliances are being formed; internal processes are now being considered for outsourcing. Work-force multiple-utilization and total quality is the objective. The Taguchi loss function is a tool to control variability of performance and energy losses are reduced to minimum and 5-E key decision areas, e.g. environmental, economy, engineering, energy, and efficiency may automatically control.
