Aerospace Instrument-Making Annotation << Back PROCESS MODELS OF FUNCTIONING OF SPACE ASSETS V.V. Shmelev This paper proposes a method of formalizing complex operations specific tasks or achieve the desired effect in the operation of technical systems of space vehicles. It is proposed graph model of the process as a set of universal schemes that are based on the modified Petri nets. Universal scheme of operation is the most common on the possibility of observing and controlling the state of the process. Modeling processes demonstrated by the dynamic processes of functioning of space assets. The way of tracking and monitoring systems operations. The model makes it possible to control the trajectory of the process. Branching trajectory of the process provided by the presence of indicator, manage and control positions. The proposed basic principles appropriate information technology. Keywords: process, process modeling, Petri nets, information technology, space. Contacts: E-mail: valja1978@yandex.ru Pp. 078-093.
