The analysis of scientific works shows that today there is no generally accepted theory of technical and economic security of the system "personnel-rocket and space complex-environment". However, it should be noted that some elements of this theory are contained in the General theory of risk assessment in combination with the methods of actuarial mathematics, as well as in combination with the methods of assessing the technical and economic costs of the creation and operation of space assets. The known methods of technical and economic assessment of costs for the creation and operation of space objects are based mainly on the cost principle and are focused on the actual costs necessary for the development, production and operation of samples of space technology, space infrastructure with the inclusion of standard profit. At the same time, many of the known methods of technical and economic evaluation of the costs of the creation and operation of space objects can be divided into the following main groups: methods of calculation, normative and parametric methods and methods of expert evaluation. When studying safety issues and preventing accidents at the rocket and space complex, it is necessary to take into account the main features of their functioning, which consist in the mandatory accounting of the properties of maintenance personnel, the actual technical means of the rocket and space complex and the environment. A feature of the system "personnelrocket and space complex-environment" is the presence of a large number of information links that characterize its information efficiency. This scientific and technical article proposes new ways, methods and means to ensure the adoption of optimal (rational) decisions to prevent accidents, taking into account resource constraints on parrying emergencies. Models of some types of resources that are appropriate to use in carrying out technical and economic calculations to solve various problems of the security system “personnel-rocket and space complex-environment”. Core results. The aggregate models of resources which are expedient to use for an assessment of technical and economic indicators of safety are developed. The problem of optimal choice of the level of accident-free SPACECRAFT in the process of flight operation with restrictions on safety using the criterion "efficiency-safety-cost" is solved, nomograms of interrelation of indicators for the criterion "efficiency-safetycost" are received». Practical relevance. The proposed models allow us to estimate the share of costs required to ensure the safety of service personnel, RSC and its components, as well as the environment.
