Conceptual foredesign of functional systems


  • Evgeniy E Smirnov St. Petersburg International Public University of TRIZ



Today's fast-developing world requires a special method to the evaluation of future events. Conventional expert approaches often do not allow to obtain an acceptable result, since they use linear techniques that do not take into account the emergence of new technologies.

For this purpose, in contemporary TRIZ there is a section that includes the trends of functional systems evolution. But the existing ways to work with trends, unfortunately, are not sufficiently algorithmized. So, it is necessary to rely either on intuition, or on passing through all conceivable options of changes. This makes it very difficult to evaluate ideas, and can lead to the fact that some of the ideas will be missed.

In the paper a systematic algorithm for conceptual foredesign of functional systems is offered. The algorithm is based on:

(1)   conceptual modeling of real objects as functional systems;

(2)   triple analysis of the models with decomposition of form, structure and functions;

(3)   life cycle analysis of considered systems and evolutionary cycle analysis of systems as classes;

(4)   analysis of functional super-systems and the immediate environment as well as stakeholders.

A visual representation of the structure of key trends of systems evolution and the principle of their application to the modification of functional systems are also considered.
