摘要: 针对目前仿真元模型的不足,引入动态影响图对策到作为仿真元模型,提出了动态影响图对策构造步骤及使用方法。仿真状态、决策方案和决策目标分别用机会结点、决策结点和效用结点表示,对手的行为采用决策者相似的决策结点进行建模。构造基于影响图对策元模型的步骤包括选择变量和确定仿真数据、确定影响图对策的拓扑结构和概率表以及检验拓扑结构和概率表。通过空战仿真实例,表明该元模型在仿真的时间演变、假设分析和最优决策三方面的应用效果较好,克服了当前元模型的不足。

Abstract: To overcome the shortcomings of the meta-model, the dynamic influence diagram game is used as simulation meta-model. A construction process and the utilization for structured dynamic influence diagram game (DIDG) are presented. The necessary simulation data are gathered for the construction of a DIDG that presents the changes in simulation state with chance nodes. The decision alternatives and objectives of the decision problem are included in the DIDG as decision and utility nodes. The adversary’s action is represented by an explicit decision node in which case an influence diagram game results. The constructed DIDG is solved to find the optimal both sides’ decision alternatives that maximize the expected value of the utility function. The DIDG is also used for studying the evolution of the simulation, conducting what-if analyses, and solving optimal strategies of the game as well as studying the strategies’ effects on the evolution of simulation. The simulation results show the construction of DIDG from simulation data and their utilization in the analysis of decision problems are feasible and effective.
