A Case Study of Productivity Improvement by using I E Tools

Abstract

This paper presents a case study in the development and application of a time study in a engine block manufacturing plant. The organization engages in the production of two produc t lines: engine blocks, heads of diverse categories. The motivation for this study was the need t o tackle the problem of productivity per shift between the employee-association and the management of the compan y regarding questions of productivity. The two products have similar production processes. The study’s most i mportant finding is that the time of producing a unit of product is directly proportional to the number of prod uction stages involved and the time spent at each stage. The study focuses on the MAHINDRA production li ne. Where stud hole and push rod operation is very important for mounting the cylinder head on cylinder b lock and how to combine this both operation on one single machine like Mahindra job. So the proposal is made t o do these two operations for HINO on BMV 60 by adjustment of special fixture like Mahindra. Wi th this proposed solution a saving of 2 to 3 man power per cycle was obtained. The paper discusses the use of Ind ustrial Engineering tools used for the purpose of productivity improvement
