One of the main tasks of the system operation of rocket-space complexes is providing the required reliability and safety of cosmodrome objects operation.
The practice of exploitation of rocket-space complexes indicates the regular occurrence of accidents on the objects of space, sometimes ending in tragedies, and in this connection it is necessary to improve the system of exploitation of rocket-space systems to ensure timely and safe execution of tasks for preparing and launching space rockets in the conditions of extreme situations occurrence. The problem of ensuring safety at hazardous facilities is currently being addressed by the use of robotic systems and complexes. The peculiarity of the preparing and launching space rockets process is strictly regulated end time to "launch window" to launch a spacecraft at a given point of the orbit. In this regard, the use of robotic systems for liquidation of extreme situations in the process of preparing and launching space rockets must ensure not only the safety of the system operation space-rocket complexes, but also the timeliness of the preparation and launch of space rockets. To ensure effective implementation of the preparing and launching space rockets tasks in different terms of the situation it is necessary to develop the model and algorithmic description of the possible normal and abnormal states of functioning of objects of rocket-space complex to estimate the probability of extreme situations occurrence on objects of rocket-space complex for their reliability and security to determine the spatial-temporal characteristics of extreme situations regions on the famous mass-energy characteristics of objects of rocket-space complex, initiating the emergence of extreme situations. Development of complex models for the characterisation of extreme situations and to determine the composition of the robotic complex to resolve extreme situations should be carried out from positions of the system approach, which consists in the consideration of the systems studied in their interrelation and interaction with the environment, based on a combination of logical, linguistic and mathematical models and algorithms, providing processing information in real time of large amounts of measurement information.
