针对补充类勤务过程仿真中补充工作介质和勤务任务种类繁多的特点,引入弱定义Agent概念,给出补充类勤务维修行为模型种类划分、行为层次输出、行为实现等具体过程,构建一种基于弱定义的混合型Agent补充类勤务维修行为模型,旨在提高机务作业训练熟悉程度。通过对黄液压储压器充氮气勤务实例建模验证其可行性和有效性。 Aiming at the variety of supplementary working medium and service tasks in the process of supplementary service process simulation, this paper introduces the concept of weakly defined Agent, and gives the concrete process of classifying service behavior models, behavior level output and behavior realization, The definition of Hybrid Agent complements the service maintenance behavior model to improve the familiarity of locomotive homework training. The feasibility and effectiveness of this model were verified by modeling nitrogen service pressure of yellow hydraulic accumulator.
