LEAN MANUFACTURING: capabilidade de processos em linha produtiva

Abstract

In this work, the main concepts and methods to determine the reliability and the capability of a process will be addressed, through analysis of variation, data collection and correction of parameters. The points to be analyzed will be presented initially to have a capable process, as well as failures and discontinuities that can occur along a productive chain. The variables for an analysis are numerous, and indexes of monitoring and definition are commonly applied, some of the main indexes that help in this analysis are the Cp, Cpk, Pp and Ppk, allied to the tools of monitoring and detection of change of behavior over time, such as control charts. Through these tools it will be possible to analyze a production process, pointing out its non-conformities, through samples and adjustments, and it is possible to conclude if the process is able to meet specific production parameters. The capability of a process can be measured by means of sampling and analysis of its behavior, and it is possible to take measures to correct the parameters so that it meets the target and meets the needs of both the customer and the manufacturer.
