There are considered scientific-methodical approaches to the formalization of methods for the formation and choice of efficient technologies ensuring a required quality of products, the decrease of labor intensity, power inputs, material capacity and cost price of their manufacturing for conditions of automated decision-making in integrated CADs. A possibility to form multivariate simulators of engineering processes and separate processing methods is shown for which there are described principles of their structural parametric optimization.

Abstract. The article deals with the issues of a computer-aided design of hydraulic equipment, namely hydraulic jacks. Design principles of the hydraulic jack CAD system are described. In addition, the possibilities for the system improvement and expansion are considered.
