“…The study consists of collecting a sample of products manufactured under standard conditions to evaluate the stability of the statistical process based on the use of control charts. Control charts are used to follow the evolution of the performance of a process (Tamer Haddad, 2021), allowing to make provision of the existence of special or common causes in the process, through unusual variability or normal introduced in it. The control charts are divided in two categories, control charts by variables, used when the characteristic / parameter to be analyzed is the type measurable and control charts by attributes used to record non-conforming units and non-conformities.…”

These days, where competition between companies is great, it is essential that they hold the most optimized processes possible, ensuring the quality of products and services and reducing operational costs. Thus, the use of tools or methodologies to meet the performance of processes and facilitate the detection of problems to reduce the variability is essential to ensure their competitiveness. The Statistical Process Control, is one of the seven quality tools used to provide information for more effective diagnosis in the prevention and detection of defects and problems in the evaluated processes and, consequently, helping increase productivity and results of the company, avoiding waste, being of greatest importance to guarantee the quality of the company. In this study, we intend to discuss / evaluate the variability introduced into a process capability study, using control charts, and having on base the use of uncalibrated measurement equipment vs. calibrated measurement equipment.

“…Some researchers use control charts as a tool to control the production process. Haddad (2021) reviews the ability of the Palestinian construction companies to apply the essential tools of SPC in their concrete production systems for process improvement [2]. Hsu, Wang, Lin, Chen and Hsu (2020) applies statistical process control and machine learning techniques to diagnose wind turbine faults and predict maintenance [3].…”

Control charts are generally use in quality control processes, especially in the industrial sector, because they are helpful to increase productivity. However, control charts can also be used in time series analysis. The residuals from the time series model are used as observations in constructing the control chart. Because there is only one variable observed, namely the residual, the control chart used is the Individual Moving Range (IMR). This study analysis the accuracy of the time series model using the IMR control chart in two models, namely the Autoregressive Distributed Lag (ADL) model without outliers and the ADL model with outliers. The results showed that the control chart could be used to measure the accuracy of the time series model. The accuracy of the model can be seen from the statistically controlled residual (in control).
