分析了由多个子系统构成的工业大系统中的决策问题，研究了各子系统之间目标出现冲突时的调解方法，采用多人多目标冲突决策模型来描述大系统中的冲突决策问题，提出了大系统中冲突的协商解的概念，并研究了其协商解的求取方法。 This paper analyzes the decision-making problems in a large-scale industrial system composed of many subsystems, studies the mediation method when there is a conflict between targets in different subsystems, and uses a multi-person multi-objective conflict decision model to describe the conflict decision in large-scale systems. The concept of the solution to the conflict in the large system is studied, and the method to find the solution to the problem is studied.
