Analysis of systems for technological chains and processes designing

The current state of the problem of synthesis of technological chains and processes of the computer-aided systems for technological processes designing was reviewed. Some publications on the results of modern research were analyzed; features of modern system’s program design were described. A classification of CAD for the technological processes of industrial and specific purpose was presented, taking into account new trends in medicine, as well as the classification methods, utilized in CAD. It is shown that the achieved level of modern theory does not allow us to create a universal synthesis technology that may be common to all subject areas. Prospects to solve the problem are associated with the construction of intelligent computer-aided design systems that implement the most common approach to synthesis, based on simulation and development activities, designed to support scientific, technical and technological solutions in the priority areas of science and technology. A general circuit of multilevel iterative synthesis process built on knowledge bases intended for storing precedents, select, configure, and options evaluating is presented. In case of absence of a suitable sample in the base, a direct synthesis of a new process is performed, using one of the possible formal approaches.
