| Abstract | The purpose of this research is to study coal blending operation model. The objective of this research is to develop coal blending operation model in order to get additional benefit from blending coals from various sources to satisfy customer demand.To develop coal blending operation model, there are 2 stages of study. First is planning stage. In this stage, the linear programming will be used to calculate the blending scenarios to get addition profit base on coal price forecast and other constraints. The output from this stage is the optimal blending plan which return higher profit to company. The optimal blending plan will be committed to customer and use for implement in next stage. Second stage is the implementation stage, this stage will develop work procedure for blending coal base on update key information such production and sales volume. The linear programming will be used to calculate revise blending plan to improve value of profit. The outputs from this stage are the work procedure for revise blending plan and information for support decision making.The results of the study in planning stage show that the EBIT from optimal blending program is 488 million USD. which higher compared with original plan which is 451 million USD. The company can get additional benefit from blending program about 8.20 % compared with original plan. The result of study in implementation stage show that the coal blending procedure which was implemented in studied company can help management to make decision and adjust production plan that more systematic and base on value management. But there are some constraints in linear programming need to adjust according to real operation of this studied company for get suitable solution for blending coal. |
