In the paper there is presented the computer program for reliability analysis of complex technical systems with reserved and improved components along with computer program description and application. The computer program allows for automatic reliability characteristics prediction of the improved complex technical systems with hot and cold single reservation of their components and of the improved complex technical systems with reduced intensities of departure from the reliability state subsets of their components. Under the assumption that system components have exponential reliability functions, the unconditional reliability function, the mean values and standard deviations of the unconditional lifetimes in the reliability state subsets and in particular reliability states, the system risk function and the moment when the system risk exceeds a permitted level of the complex technical systems before and after their improvement are determined.
