Two linear programming (LP) models for accomplishing decisions at the first two levels are developed. Both LP models address the aggregate planning process. The first model, the mine production scheduling model, permits determination of monthly production and inventory levels. The objective is to minimize the monthly production and inventory holding cost of the schedule. The second model, the sectional production scheduling model, incorporates a quality blending requirement into the determination of the weekly sectional production and inventory levels. The objective of this model is to minimize the weekly production and inventory holding cost. FiguresReferencesRelatedDetails Recommended Vol. 04, No. 01 Metrics History PDF download
