- Measurement Processes Evaluation: Comparative Analysis between the Shewart Control Charts and the R&R Studies Gloribel Pérez Pérez Administración y Contabilidad The main objective of this investigation is to analyze and comparetwo methodologies used to understand the different sources ofvariation contained in the measurement process. The two methodscompared are the Foundation of Shewarts Control Chart and theRepeatability and Reproducibility Studies (R&R) Study). Theinformation related to both methods is used to compare them. Theobjective is to evaluate the techniques used to study the sources ofvariation in a measurement process. Also to evaluate and identifythe situations where the Shewart Control charts are more efficientthan the Repeatability & Reproducibility Study in the evaluation ofa measurement process.An evaluation and compilation of the information related withthe Repeatability and Reproducibility (R&R) Studies and the ShewartControl Charts to evaluate the measurement process was conducted.A manufacturing process was evaluated using both methods and itwas determined which method is more efficient in identifying sourcesof variation in the measurement process. In addition to themanufacturing process, data was randomly generated through theuse of statistical software and analyzed under both methods, R&RStudies and Shewart Control Charts.Based on the data obtained in both methods in the manufacturingprocess, it is concluded that the Shewart Control Chart (EMP Study)is more eff icient in identifying sources of variation in themeasurement process. The R&R Study does not have the ability todetect the measurement unit adequacy. If only the R&R Study wereapplied to the manufacturing process, no action would be in placebecause an R&R%<30% was acceptable for this kind of process. Inthe random generated data it was found that a low (CPK) resulted inhigh R&R% and a low Discrimination Ratio. In order to better identify the sources of variation connected with the measurement process, itis concluded the Shewart Control Chart (EMP Study) if more efficient.It is also recommended prior to any conclusion to determine theusefulness of the measurement units. 2002 artículo científico 1541-8561 https://www.redalyc.org/articulo.oa?id=63170108 en http://www.redalyc.org/revista.oa?id=631 Forum Empresarial application/pdf Universidad de Puerto Rico Forum Empresarial (Puerto Rico) Num.1 Vol.7
