Abstract:

Portfolio of weapon system-of-systems(WSoS) is a complex systems engineering task, bearing significant military implications and research value. This paper considers the complexity and the correlations of the WSoS, and from the perspective of the system-of-systems, proposes a WSoS portfolio development method, which provides an idea for the equipment development demonstration. Firstly, based on the interrelationships of various types of weapons, this paper constructs a heterogeneous information network model of weapons and extracts the functional chains, providing a foundation for subsequent models. Secondly, considering the uncertainties in portfolio of WSoS, a multi-stage portfolio of WSoS model is established. Then, a double deep Q-network (Double DQN) algorithm is designed to solve the model. Finally, taking an example of a WSoS development planning, a demonstration calculation is carried out to verify the effectiveness and feasibility of the proposed method.

Key words: weapon portfolio, heterogeneous information network, deep reinforcement learning, weapon development planning
