Otimização de linhas SMT utilizando análise de CPH: estudo de caso em fábrica de produtos eletrônicos automotivos.

Abstract

The use of resources in a lean way is extremely important for the performance of a company, because it avoids waste and unnecessary manufacturing costs. For a company to remain competitive in the market, it is necessary to ally competitive price and quality. For this to be possible the production cost must be as low as possible, so that the organization's profit margin becomes higher. This study aims to study the advantages of applying CPH analysis in order to identify opportunities for improvement in the production process of SMT in a factory of automotive electronic products in the Industrial Complex of Manaus. To achieve the proposed objective, a quantitative approach was used, of applied nature, through data collection and CPH analysis, guided by the DMAIC methodology for project planning and execution. Using the Chronoanalysis technique, 27 products were identified with a level below that required by the company. From the simulation of the process in the SMT Load Forecasting tool, improvement actions were pointed out to optimize the level of equipment utilization. After the implementation of the improvement actions, the required efficiency percentage was reached and the production capacity of the lines increased by 11%.
