<p>For determining an input material mix for a kiln, where the cement kiln is fed with input materials, and said input materials are classifiable as raw material, fuel and waste, the following steps are executed: determining constraints on the operation of the kiln and expressing said constraints as functions of feed rates for the raw material, fuel and waste; determining a cost functional that represents total operating costs of the kiln over a given period of time and as a function of the feed rates for the raw material, fuel and waste, said cost functional including costs of raw material, costs of fuel, costs of waste and revenues from the product; and determining trajectories of the feed rates for the raw material, fuel and waste that minimize the cost functional and satisfy said constraints. <??>The invention allows determining a mix of input materials that minimizes a total cost of kiln operation over a given period of time. <IMAGE></p> |
