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...

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...
