Review of Increase in Productivity of an Industry by Applying Lean Manufacturing Process

Lean manufacturing is defined as a systematic approach to identifying and eliminating waste through continuous improvement, flow the product at the pull of the customer in pursuit of perfection. Implementation of lean manufacturing is very helpful to all manufacturing arrangements, it reduces all kinds of waste and non-value added activities. Lean is very wide concept. Here I motivated to apply lean concepts in manufacturing system i.e. automobile industry. Today industries are facing various problems related to quality and customer demand. The present study has been undertaken for analyzing different types of wastes in a Diesel Locomotive Plant’s Light Machine Shop (crankshaft section) with an aim to design strategies for developing and implementing a Lean Manufacturing Program in such machine shops. The study has been carried out in a phased manner. For the purpose of modeling for developing a strategy for implementation, the controls identified have been grouped into broad, generalized category. Expert opinion has been utilized to identify factors and parameters affecting the development of a generalized approach for implementation. Generalized of various measures for developing an approach to be used by industry in the future has been suggested using expert belief. It has further been suggested that the implementation of the development approach be carried out in three phases. With the help of lean we increase production rate and improve quality.
