Optimization of Modular Update Strategy for Launch Platform of Launch Vehicle

A strategy is proposed to divide the launch pad into multiple modules and update them according to the modules, in response to the practical problems of high cost of carrier rocket launch platforms and difficulty in fully utilizing the lifespan of some components under high-density launch missions. We constructed a modular update strategy optimization model and designed a model solving method. Application examples show that updating according to modules can effectively reduce the cost of launch pads in high-density launch mission situations.
