The effect of national quality awards on the market value of the award-winning companies is an ongoing study in many countries, but relevant studies are difficult to find in Taiwan. This study empirically examines the market valuation of firms that undergo effective quality improvement programs...

This research develops a demand management system, incorporating a machine-rate model, a rough-cut capacity planning (RCCP) model, and a demand management model for the fishing-net production industry. The machine-rate model is used to calculate a machine workload for the RCCP model to estimate...

In recent years, the exponential-weighted-moving-average (EWMA) statistic based controllers are popular in semiconductor manufacturing. However, the single EWMA controller is not sufficient for compensating for the wear-out process. Thus, a double EWMA controller was proposed to enhance the...

Despite their diverse applications in many domains, the variable precision rough sets (VPRS) model lacks a feasible method to determine a precision parameter ([beta]) value to control the choice of [beta]-reducts. In this study we propose an effective method to find the [beta]-reducts. First, we...
