“…MSA is an analytical tool composed of principles for evaluating the measurement system. The main aim of MSA is to determine the effects of different variations in measurement process; thus, statistical approaches are employed to highlight the reproducibility and repeatability of the measurement (Dalalah and Diabat, 2015). Gage Control was decided to be used because of its ability for validation and verification of the data collection process.…”

Since every mistake made in the healthcare industry can cause permanent harm or even death, some fundamental requirements should be considered when planning and designing operating rooms. Lighting is one of the most important ergonomic factors, especially for operating rooms. This paper investigates the integration of the lean approach and six sigma in measuring the efficiency of LED technology, which can also be regarded as a factor affecting the operating room efficiency. Measurement System Analysis (MSA) and Gage Control methods were applied to determine measurement variability in operating room illumination measurement process. Repeatability and reproducibility (%R&R) was found 12.89%. After calibration, %R&R value was found 8.21%, which implies that calibration helped reduce variability.

“…Asplund and Lin [13] conducted a Gage R&R study to evaluate the capability of the wheel profile measurement system in CBM applications. This technique has been employed to investigate the capability of various measurement systems and to identify the root causes of measurement inconsistencies in diverse fields [14][15][16][17][18]. However, there can be misjudgement in cases when a sensor experiences partial malfunction, yet remains capable of transmitting signals.…”

Acoustic Emission (AE) is a pivotal technique in Condition-based Maintenance (CBM) and recent years have witnessed a significant surge in the deployment of AE sensors in industrial applications. With this increase in availability, there comes a substantial challenge: evaluating the measurement capability of sensor within specific applications. As such, this study identifies a critical need for a structured approach to evaluate the measurement capabilities of AE sensors and subsequently judge their acceptability against guideline criteria. To address this need, we present an integrated approach that systematically guides the capability evaluation of AE sensors, incorporating both qualitative and quantitative analyses. The qualitative analysis aims to scrutinize the accuracy of sensors by assessing the detectability of features critical for diagnostics. The quantitative analysis leverages the Gage Repeatability and Reproducibility (Gage R&R) to statistically evaluate sensor characteristics. A comprehensive experimental study further investigates the impact of measurement sources on the sensors' accuracy, repeatability, and reproducibility. This study illustrates the qualitative findings regarding sensor accuracy in both time and frequency domains, revealing promising performance in diagnostic-based evaluations. In quantitative analysis, we demonstrate the results of sensor capability in terms of repeatability and reproducibility, providing the variations of different sources in statistics-based evaluations. We thoroughly investigate the influence of significant factors, quantifying their contributions to sensor’s measurement capability. Furthermore, we introduce metrics designed to assess sensor’s acceptability, according to explicit acceptance and rejection criteria. Our experimental results affirm that Root Mean Square (RMS) measurements are within acceptable ranges for both sensors, while Spectral Entropy (SE) measurements for PK15I sensor satisfy the acceptable level. For HZ136I sensor, however, SE measurements are deemed conditionally acceptable. Ultimately, the proposed approach provides a robust framework for the comprehensive evaluation of AE sensor measurement capabilities, offering invaluable guidance for sensor selection and enhancement in industrial applications.
