Summary: The Model of an ICAE system is developed. Influencing factors were subject of research defining product's properties, by the potential relation market. By appropriate design process level, the appropriate solution level is achieved as well. Design process development included the automatization of assembly modelling, by flexible program structures. The hierarchical data structure was applied with virtual links between nodes. A description language is necessary for the manipulation of such a model. Compilation of classical CAD systems and it's properties has lead to an network model conception. This model can be adapted to different problem domains by design protocol. A brief method for recording relative entity positions in a variant drawing is proposed. Program system is adaptable to different CAD systems. In a purpose to transform geometrical informations to technological operations, the classification system and principals are defined. The method is verified by the drilling technology classifier. A successful application of such a system is aided by appropriate user interfaces. A communication model for designer is developed. This model is tested on a tool for design of mechanical power transmissions.

Keywords: CAD, CAE, Expert systems, CAM, PPS

Research goals: During the planning of this project the main goal was defined as development of the model for integrated CAE system. The system should serve as a tool for product design, as well as designing the technological procedure of its realisation. An anticipated modular structure of the system has to enable individual application of the realised modules and the successive automatization level growth, implementing AI methods. Main properties of such a system are: - possibility to change the assembly structure, - possibility to integrate the tools for design, supporting all phases of design process, - integration of such system with existing CAD systems, - support for design with features, - representation of heuristic knowledge. Expected contribution of such research is a model of the system that enables manipulation of numeric and symbolic information over all design process phases. The automatization of planning a single technological operation, as a basic unit of process is considered too. This segment is applicable for integration in the CAPP system.
