In response to the characteristics of single-equipment and single-mission in space launch tasks, a task-scenario-based assessment method for the contribution rate of launch vehicle systems is proposed. The algorithm and software are implemented, and the correctness and effectiveness of the method are verified through computational examples. Firstly, starting from the characteristics of launch vehicles and space missions, the space mission and rocket capabilities are decomposed to construct a ″mission-capability″ mapping matrix; Secondly, based on this, an assessment chain for the contribution rate of the launch vehicle system is established; Finally, a mission-scenario-based assessment algorithm for the contribution rate of the launch vehicle system is designed, and an assessment software for the contribution rate of the launch vehicle system is developed. Application examples show that the calculated data and assessment results are consistent with the actual situation, verifying the accuracy and effectiveness of the method, and achieving good application results.
