A CONTRIBUTION TO METHODOLOGY OF ENGINEERING CALCULATIONS
The paper presents a new methodology of engineering calculation algorithmization based on constraint management. The constraints and variables are represented in a Boolean matrix form called the occurence matrix. The analysis and decomposition of the occurence matrices are described, which results in their re-ordering to a form convenient to the algorithmization procedure. It is outlined and then applied in setting-up a calculation algorithm for helical spring. It is shown that the method enables the user to have a full insight into complex relationships among variables and constraints and to find the most efficient sequence of computations. The method deals not only with equations but also with inequalities, tabular data, graphs and other.
