CV CSM is a metal manufacturing company where extensive cutting processes on its production floor generate dust particles and oil mist, posing potential hazards to workers. Currently, the air quality at CV CSM remains poor, with a single air quality monitoring device centrally located on the production floor. It is uncertain whether the selection of this point accurately represents air conditions across the entire area. Consequently, a multi-point AMOR placement was developed. AMOR placement determination was based on an error-based approach to select the most representative locations for air quality monitoring. Before development of the placement, the performance of AMOR was evaluated. Results indicated that AMOR's particle concentration measurements showed good linearity for PM2.5 (R^2 = 0.724 - 0.972) and PM10 (R^2 = 0.680 - 0.914), but the accuracy for PM2.5 (54% - 83%) and PM10 (34% - 73%) were less satisfactory. AMOR is less precise in measuring high particle concentrations. AMOR was also found to measure PM2.5 concentrations more effectively than PM10, with a longer response time compared to the reference instrument and a larger PM10 measurement range than the sensor specifications. The error metrics used in determining multi-point AMOR placement is root mean square error (RMSE) and mean absolute percentage error (MAPE). AMOR was proposed to be placed at eight points in Layout 1, which provided the minimum RMSE and MAPE values. The minimum number of AMOR units required on the production floor is seven, with placements at certain points in Layout 1, achieving a MAPE of less than 1%.
