Typically, a marble factory has various processes for different types of marble. Due to diminishing resources and higher competitiveness in the market, optimisation of the marble processing operation has become crucially important to sustain business. Traditional operational policies in a marble factory are based on heuristic approaches and do not guarantee an optimal result for complex processes. There are not sufficient published works based on mathematical programming models in optimising the factory processes for complex marble operations. This paper, by E. Topal and M. Ayhan, presents a new linear programming model for optimising production planning in the marble industry. The new linear programming (LP) model is developed to maximise the net profit for a marble factory by identifying the type of marble and the optimal quantity of that marble (m2) for each type of existing various processes. After calculating all the costs, including the operating cost of the process from raw material to product packing, and revenues, the new LP model is generated for a marble factory with complex operation systems and solved. The new LP model generated superior results and significant economic increase for the marble factory compared to current operation. In the first part of the study, all the costs including all the operating costs from raw material costs to product packing costs and capital costs, and revenues, were calculated in order to generate the model. In the second part of the research, the new LP model is generated for a marble factory with complex operation systems and solved. The last part of the work, the generated plan was evaluated and compared with the current plan with respect to income and applicability.
