Аннотация:The principles of designing computer-aided graphics and machinery manufacturing systems are presented. The system reliability index is proposed as the flexibility criterion. The highest efficiency may be attained using integrated systems of design and manufacturing. The problems of integration of the above systems and ways for their solution are shown. The integrated machinery production system KAPRI being developed and the steps put into operation at the Kurchatov Institute of Atomic Energy are briefly described. The KAPRI system involves complex of functions of computer graphics, technology design, manufacturing of pilot-devices and control of design and production process.
