Abstract
A process for the prediction and the optimization of the output of a plant producing products form incoming materials. The incoming materials are classified according to various physical characteristics and costs. The desired or ordered products are also classified according to price and physical requirements. The incoming materials information and the product information is entered into a database which is accessible by a computing device. The computing device then calculates the optimal production process by calculating a plurality of production cycles and selecting the cycle with the optimum profitability. The computing device is programmed with non-linear equations derived from a regressive analysis of data collected from samples of incoming materials and products.
