  Considering profiles as functional variables, two control charts are proposed for their monitoring in phase II. Due to its conformity with the nature of real-world profiles, applying functional model leads to proposed control charts obtained through functional data analysis techniques with desired features. These include simplicity in calculation and possibility of using them for different profiles such as linear and non-linear (even in the presence of complex within-profile Autocorrelation forms). These features distinguish the functional model from the regression models common in profile monitoring. Simulated computer simulations show that, in different states, the proposed control charts have a lower average run length than other methods, which indicates the desired performance of the proposed functional approach. Morevere, in some non-linear cases with complex autocorrelation, other methods completely fail, and only the proposed control charts are able to detect the occurring deviation, and even in these cases, the average run length of these control charts is highly desirable.

  The main purpose of this paper is to estimate the process quality estimation by using control charts type X-R and quality capability of the process. The population of research was 170 senior executives, middle managers, quality control, and support staff from Ilam cement manufacturing International Corporation. Using Cochran formula, 118 subjects were selected out of the total number of the population. Using multiple linear regression, random selection of the population was done. Then, the collected data, which was collected by using a standardized questionnaire were analyzed by using Spss software. Results showed that the type of material and equipment will affect the charts, but operators and technicians in the production process cannot affect the graphs. Also, the result showed that such factors as the customers and market, operational conditions, sampling are affecting the capability of the production process.                                         Manuscript profile
