摘　　要：文章针对复杂产品装配过程影响因素众多、难以控制的现状,设计了一种对其进行异常控制的策略。首先确定造成装配过程异常的原因,进行异常归类,并对异常控制所需采集的信息进行分析;其次引入工段信息元概念,在此基础上建立复杂产品装配过程实时状态模型;最后基于该模型构建异常控制专家系统,为装配过程提供实时异常报警信息及相应处理方案。结果表明该异常控制策略具有很好的实用性。An abnormal control strategy is designed in this paper,aiming at solving the problem that the complex product assembly process is hard to control for so many factors may affect it.Firstly,the causes of the abnormity of the assembly process are determined and classified,and the necessary information on controlling the abnormity is analyzed.Secondly,the concept of workstation information cell is introduced to build a real-time status model of the complex product assembly process.Finally,an expert system of abnormal control is given based on the real-time status model to provide real-time exception alert information and corresponding disposal options.The result shows that the abnormal control strategy works well.
