System of designing complex technical means using fuzzy analysis

This paper presents the concept of the system adding designer work using fuzzy analysis of the notes of design requirements and solutions. Design requirements are generated basing on the proposed model of the technical mean life cycle. It includes three phases of life of a technical mean: its formation, its existence and its liquidation. In this perspective there are examined five general requirements associated with: the technical need, a man, the technical culture, the society and the environment. The design solutions are created basing on the concept of an universal structure of technical means. The structure of the system has following components: structural system, drive system and control system. Structural system is determined as the integrator of the whole structure of a complex technical mean. The drive system is secondary to the structural system. The third in the order of the systems is the control system. It is developed last so it must take into account the solutions developed for the structural system and the drive system. Generating constructional solutions is carried out in the three distinguished features of a construction: geometric, material and dynamic. The presented methodology is illustrated by the example of designing specific technical mean.
