IMPLEMENTING A BLENDING OPTIMIZATION MODEL FOR SHORT-RANGE PRODUCTION PLANNING OF CEMENT QUARRY OPERATION

摘要

An application of the linear programming based blending optimization model for short-range production planning of the cement raw materials is presented. The benefits of the model are established through a case study of an existing cement manufacturing operation in the northern part of Pakistan. A successful model implementation has ensured significant cost savings, reduced employee time for preparing schedules, a sustained supply of raw materials, and better coordination and engineering control among various divisions of the operation as compared to schedules produced manually.
