Based on particle swarm optimization, a method for optimizing the layout of the back-up display-control panel is proposed for design of a human-machine interface of a nuclear power plant' s main control room, to avoid the subjectivity and randomicity in layout due to designers' experience. The method is described below. In accordance with the importance of ergonomics principles, operating frequency, operating order and correlation, a layout optimizing mathematic model is structured. Then an objective function is formed in order to transform the layout problem to a mathematic problem. At last a layout result is carried out using particle swarm optimization. An implementation of 16 control and display components was tested, showing that this method is effective for back-up panel interface design.%针对目前核电站主控制室后备盘台人机界面设计过多依赖人的经验和主观判断从而导致控制面板布局随意性的问题,提出了基于粒子群优化算法的控制面板布局设计优化方法,即先对控制面板上元件的重要性、操作频率、操作顺序和相关性等工效学布局原则分别进行数学描述,并依此构造布局优化目标函数,将布局问题抽象为数学问题,然后采用粒子群优化算法对布局优化目标函数进行求解,以便快速地找到最优布局方案,从而达到布局优化的目的.通过对16个操纵和显示元件进行布局优化计算,证明了该方法能有效地解决后备盘台人机界面布局优化问题.
