An Optimization Framework For Missile General Design With Multi-method Collaboration Support

The information military transformation accelerates the change of missile operation styles, and demands higher and stricter standard to missile general design, which should be focused on the balance among performance, cycle, cost, adaptability and reliability. The practice of engineering shows that single optimization algorithm can not fit the complex application needs, while multi-method collaboration optimization (MCO) is widely recognized for its well performance. However, the applications of MCO have some difficulties in the missile general design, including the selection of optimization algorithms and the automatically scheduling of multi-method collaboration optimization plan (MCOP).This thesis brings forward an optimization framework for missile general design with multi-method collaboration support, as well as corresponding key technologies. The above problems would be solved to a certain extent and the efficiency and quality of missile general design optimization would be improved. The main work and innovation of this thesis can be concluded as the following three aspects:â‘ To solve the problems in the use of MCO above, the thesis proposes an optimization framework for missile general design with multi-method collaboration support, and presents the reference process of the framework. This framework should provide methodology guide for MCO and promote the improvement of efficiency and quality of missile general design optimization.â‘¡Aiming at the needs of evaluation and selection of optimization method, this thesis proposes the selection rules of optimization method based on applicability evaluation and optimization strategy. First, this thesis presents the evaluation of optimization method based on analytic hierarchy process. Then, combined with optimization strategies, this thesis presents the multiple method selection schema and corresponding process. The method would improve the efficiency of missile general optimization design.â‘¢Aiming at various scheduling needs of MCOP, this thesis proposes the directed graph based MCOP scheduling method, which refers to graph scheduling thoughts in parallel computing area. The directed scheduling graph model is based on optimization method component. The method can support the automatic execution of optimization scheduling process, and improve the efficiency of missile general design optimization.
