RMS research based on three dimension model of support system with simulation method for military aircraft

The issue of how to obtain reasonable reliability, maintainability and supportability (RMS) design parameters in the development of military aircraft was researched.The framework of RMS design parameters simulation model was constructed via the three-dimensional model of support system and the rule of modular design principle. The framework contains four modules includinag mission module, function model, operations and maintenance model, support organization module and which are the kernel of the framework. The relationship and the content of data streams between these modular were expatiated. According to the definition of evaluation parameters, the method of how to calculate them using simulation data was given. To verify the feasibility and validity of the simulation framework, the Monte Carlo simulation is used in the trade-off RMS design parameters and a family of design values fulfilling the constraints of support effectiveness requirements is obtained.
