Application of Discrete Event Simulation to proposals for improvements in an automotive assembly line

Abstract

Many companies are using lean manufacturing in an attempt to reduce costs through the elimination of waste. Changes in the manufacturing environment eventually lead to high investment, so it is important to first analyze the possible results. This paper aims to validate proposals for improvements in the productivity of a manufacturing line by the use of discrete event simulation. The simulation model that was created could provide the decision-makers with useful information, such as the production rate, changes in the number of workers and in shifts, and the order that jobs are processed. Our conclusions are that the simulation technique can present a set of viable scenarios for improvement and for choosing the best one according to a company’s strategic objectives.
