Multi-objective optimization based on the integration of Linear Physical Programming within Analytical Target Cascading

The large-scale complex system of the practical engineering design always contains multiply optimization objectives and multiply disciplines. Aiming at the large-scale system Multidisciplinary design optimization (MDO) design problem with the serious conflicts between the different design objectives, we describe the integration of Linear Physical Programming within Analytical Target Cascading framework in this paper. The proposed framework would enable designers to formulate multiple system-level objectives in terms of physically meaningful parameters, and would hierarchically decompose the multilevel system into several small and more manageable subsystems for saving computational cost. A mathematical example using MDO method demonstrated the proposed framework.
