Abstract

Reliability and safety are the clue problems during creation and operation of space facilities and realization of space programs. Effective solving of these problems, in many respects, is determined by availability of complete and certain information concerning achievement of required levels of reliability, safety, quality and technical state on the all stages of designing, testing and operation.

As practice testifies, for years of space activity designers and manufacturers has accumulated the immense information content obtained during designing, ground and flight testing, special usage of launch vehicles, spacecrafts, ground equipment, etc. However, at solving of problem questions inevitable appearing during the operation of existent space facilities or creation of advanced items of rocket-and-space engineering and development of new space programs given information is often used ineffectively or isn’t quite used. Such state of affairs deals, in the first place, with difficulty of access of information (most of data are on paper medium, didn’t convert to electronic type and have filed or even deleted), and, in the second place, with lack of proper succession of generations when information “is lost” after experienced specialist retiring.

By now existent reliability and technical state databases are part of the solving for this problem. However, incompleteness of stored data, outdated principles of organization, in a number of cases, and other reasons reduce their practical significance. Furthermore, at present, in conditions of headlong increase of information flows, specialists and decision makers wouldn’t like to get merely information. They have no time to retrieve the necessary information and would like to have end result. That’s why, it’s necessary to have possibilities of various quantitative and qualitative evaluations, that is the base for following analyze and synthesis at reliability and safety problems. Therefore, created information systems are to have so-called analytical properties as well.

For solving of this problem, developments of computer-based information-analytical systems of assessment, verification and forecasting of reliability and technical state of launch vehicles and spacecrafts are directed. The main goal of these systems is support of day-to-day reliability and risks management for all the stages of designing, testing and operation. The paper will review major tasks of referred above systems, principles of their organization, directions of their elaboration, and prospects of usage.
