Abstract: The design criteria, operational frequency, operational order and compatibility are proposed and analyzed for nuclear power plant main control room. A layout optimization mathematic model is created based on these rules. Objective function of the mathematic model is developed, in which the distance of hands’ moving is added in order to measure the workload of operators. An example of 12 components on panel is implemented by particle swarm optimization.

Abstract: Panel layout in control room of nuclear power plant requires satisfying layout principles and requirement for multiple operational conditions. Traditional panel layout methods are difficult to integrate these principles; the layout scheme heavily depends on designers’ individual judgments and experience. So the randomness of layout scheme is hard to overcome. Particle swarm optimization is a global efficient solution to complex optimization problems with multi-constraints. First, the operational efficiency is selected as optimization object. Second, objective function is constructed according to the evaluating indexes which include operation frequency, sequence and importance of components. Third, Particle swarm algorithm was used to optimize the layout scheme. A case study of layout optimization design is conducted to illustrate the proposed method.

Abstract: . A novel method for layout has been proposed for control panel. Six layout principles of ergonomics are taken into consideration to reduce the influences of indeterminate factors caused by the subjective judgments of designers. Optimization method and function is constructed to optimize the layout result based on genetic algorithm. And a computer-aided layout system is developed based on UG/OPEN API to realize automatic layout by computer. A detailed example of control panel layout of a thermal power plant is provided. The result shows that the efficiency and quality of layout are improved by this method.
