Application of the control chart for variables in a vehicle assembly plant in the south of the state of Rio de Janeiro

Abstract

Vehicle assemblers have quality as a prerequisite for the proper functioning of their process. The monitoring of the quality of this type of industrial activity is carried out by means of control charts by variables. The objective of this article is to show a case study carried out in a company in the south of the State of Rio de Janeiro that used this type of control chart, more specifically the control chart of the mean and amplitude to evaluate a process carried out by three machines. The results showed the need for some adjustments and managerial attitudes will be taken to improve the process.
