The paper presents a methodology to analyse the probabilistic performance of separation process satelites and launch-vehicles (boosters). Models of spacecraftdynamics are considered with taking into account the liquid fluctuations in the fuel tanks. All the design uncertainties are modelled as random variables. The probabilistic characteristics of the critical separation parameters are estimated by the Monte Carlo method. The methodology allows to perform the statistical computer simulation of the separation and it is confirmed by the corespondence of the forecasted performances with data of real launches.
