Abstract: In the project activities related to the creation of complex technical objects, apply automation design. The design process seems different models depending on the purpose of the application of these models adopted forms or rules of their construction. The concept of a formal representation of the design process, described in the works of Yoshikawa, was further developed in the theory of computer-aided design. During the design stages of release, project procedures and project operations. Stage consists of design procedures, each of which in turn includes a number of project operations. Project operation is a separate step in the design. Each design proce- Mr. completed design decision. In practice, the design of controlled-use network model, which is an organizational tool for project management. The main elements of the network model are: work, and the way the event. In the model, a network schedule, the complex design procedures depicted as a directed graph, which reflects its logical sequence and duration of the relationship. Gantt Chart is the most obvious way of presenting the project schedule.
