The study tested the optimization problem of design and engineering characteristics of
spacecraft groups, its solution requiring the probabilistic approach. We evaluated the
indicator of the target program performance effectiveness with minimized costs. Moreo-
ver, we developed the methods and software to optimize the probability of failure and the
redundancy multipleness of on-board systems, as well as the resource, the number of
substitutions and the number of redundant spacecraft. While using optimization tech-
niques, we also applied Lagrange methods, as well as search and random search meth-
ods. The efficiency of the proposed approach is illustrated by definite examples. The find-
ings of the research can serve as a guide for engineering and technical personnel of en-
terprises in the development of highly reliable products of rocket and space technology.
Keywords: space group, reliability, resource, redundancy multipleness.
