Application of decision support technology at various stages of the life cycle of space facilities in assembly with the information system of technical condition and reliability

The paper presents an approach to assessing structural states of space vehicles (complex organizational and technical objects) with support of taking decisions on their life cycle control. The analysis of the subject area showed the need to apply the new intellectual information technology presented in the article to the design of both the information system of a complex organizational and technical object, and the related systems for monitoring structural states and decision support as part of such an information system. We consider a version of a generalized computational model as a theoretical basis of this technology. The version discussed is a unified knowledge representation model that integrates a number of methods and approaches of the Artificial Intelligence theory and makes it possible to construct imitation-analytical polymodel complexes for monitoring states and controlling complex organizational and technical objects. The article shows that applying this technology allows comprehensive assessment of the technical state and reliability of the monitored object. The article also provides a brief overview of the software complex that solves the problems of estimating the structural states of space vehicles. The software complex is implemented on the basis of the examined intellectual information technology.
