Aerospace Instrument-Making Annotation << Back DISTRIBUTION OF RELIABILITY REQUIREMENTS FOR THE FUNCTIONAL ELEMENTS OF THE SPACE SATELLITE ONBOARD EQUIPMENT TAKING INTO ACCOUNT THEIR IMPLEMENTATION POSSIBILITY V.A. Zelentsov, A.N. Pavlov The article discusses the algorithm for requirements distribution for the values of the reliability indicators of the space satellite onboard equipment functional elements in consort with the procedure for choosing a specific composition of these elements from the available nomenclature. The requirements distribution task is posed and solved in a multi-criteria setting, when determining requirements, both the values of the functional elements reliability indicators and the values of other quality indicators: mass, energy consumption, etc. are considered. This task takes into account the main features of the space satellite as a structurally complex system, including various types of redundancy and multi-mode operation. The solution of the problem is presented in the form of a Pareto-optimal options table for the composition of on-board equipment, which allows the developer to vary the options for the equipment composition and requirements distribution for the functional elements reliability, as well as quantify the losses and increments in the values of quality indicators when moving from one option to another. Keywords: reliability, requirements, onboard equipment, space satellite, structurally complex system, multicriteria optimization. DOI: 10.25791/aviakosmos.12.2022.1310 Pp. 03-13.
