Abstract

Apparatus for the prediction of performance parameters of a proposed machine, in particular, an agricultural machine, includes a keyboard for entry of data in accordance with a set of input parameters useful in the calculation of performance parameters, a display for displaying performance parameters, a memory for storage of data inputted by the keyboard, and a data processor interconnecting the memory and the numerical board for performing mathematical calculations to output values of the performance parameters in response to the inputting of data at the keyboard. Included within the data processor is an analyzer for selecting input parameters specific to a mathematical correlation, a microprocessor for calculating values of intermediary parameters from the inputted data based on patterns of such data, and a synthesizer employing values of selected input parameters and the intermediary parameters to provide mathematical correlation for attaining values of the performance parameters.
