Structural-Parametric Model of the Design System
Purpose of research. In the design process developers dealing with professional issues related to the development of new design methods and tools inevitably face problems associated with the modeling of automated and designed objects. The analysis of the problems of designing complex systems have shown that the disadvantages of the design process appear, in particular, due to the incomplete generation of possible project options, as well as their partial ordering. At the same time, there is a certain imbalance in the properties of design systems and the problem of the lack of adequate methods for describing design processes arises. Methods. In the process of partial ordering of acceptable project options, when determining the structure of the design system at the generation stage, the structure of some generative grammar is used, which should have, first of all, control properties that provide a partial ordering of options already in the generation process. In addition, to take into account changes in the composition and parameters of design solutions, the generative grammar must have adaptive properties, which determines the need to choose an appropriate method for adaptive control of the generation process, taking into account, for example, the frequent repetition of the design process. Results. A model of a formalized recognition system is determined when choosing a project variant presented in the class of recognizing grammars. Rules for the formation of elements of recognizing grammars are given, and the alphabet can be represented by a multi-alternative probabilistic network of design options. The choice of the design object type is considered, the elements of the design system structure are determined. Conclusion. The structure of the design system can be parametrically determined based on the rules for generating elements of recognizing grammars, and the possibilities for generating variants can be coordinated with its recognizing capabilities, while the choice of the structure and forecasting of project parameters is made taking into account the number and properties of design resources. It should be noted that providing only the properties of the design system that reduce the description of the process can lead to difficulties in recognizing variants. At the same time, the choice of an adaptive design system structure allows you to build a language system with variable properties that provide the required reduction or expansion of the project description.
