An Inexact Fuzzy-Queue Programming Model for Coupled Coal and Power Management

In this study, a coupled coal and power management model is developed based on an inexact fuzzy-queue programming method. The model is applied to a case study of coupled coal and power management system. The results indicate that the developed model can afford reasonable measures for solving coal-blending and coal-resources-allocation problems in coupled coal and power management system. It is useful for (a) standardizing coal supply, (b) improving efficiencies of the boilers, and (c) reducing emissions of air pollutants for meeting local air-quality targets. Potential risks associated with coal shortages and instability due to property variations from multiple sources can also be highly lowered through diversifying coal sources. Moreover, it can handle queue problems and multiple uncertainties exist in coupled coal and power management activities. Thus, it can help decision makers obtain optimal coal-blending schemes and coal-allocation patterns.
