Detailing the idea of the design process of hydraulic automation objects

The work is touched to the design methods of the complex technical objects. The reason of the objects complication is the requirement of the dynamical processes coordination because the planed characteristics are needed. The main design stages idea – circuit diagram – simulation – structure are considered. The means of the design stages information representing of traditional approach are the relatively commonly and not consistent. It leads to design time increasing. In this work to structure the design information, coordinate the means of the different stage information representation with each others and detail design process are proposed. To do it the common information space of knowledge of the subject aria are separated on the streams. The streams represent information about the content, uniting, activities and requirements. The design process is represented as the transactions chain. Each transaction is based on the named streams and successively forms the state of the resulting functional stream. These states reflect the readiness levels of the designed object. Due to this way of means representation and detailing of information the coordination between different stages was provided.  There are the possibilities to check the stage correctness executing also. As result the iteration reducing and time consumption of the design process are reached. The design process is illustrated by the example.
