An Improvement of Raw Material Incoming Inspection Process by Implement Lean and IE Techniques

Abstract— The objective of this paper is productivity improvement by means of Lean Manufacturing Principles in the automotive manufacturing industry. Lean Manufacturing is a popular tool to be implemented in automotive industry fields for the purpose of achieving successful production goals and it is a well-organized method used to eliminate waste or non-value-added activities. In this paper, the author is focused on IE Techniques which are work study and ECRS technique. This was obtained by decreasing the manufacturing cost by reducing the cycle time of raw material incoming inspection process and reducing workforce. An improvement in a case study of automotive manufacturing company was achieved by minimizing the cycle time. The suggestion for improvement by changing the measuring equipment and changing the sequence of raw material incoming inspection process can reduce inspection time from 3.64 hours per lot to 1.70 hours per lot, introduce new automatic collect data equipment (U-WAVE) can reduce re-inspection time by human error from 70.94 hours to be zero hours and set up the new standard of raw material incoming inspection level can reduce inspection time from 390.83 hours to 16.03 hours.

Index Terms— productivity improvement, lean thinking, Waste(Muda), ECRS, Barnstorming.
