Abstract:

To obtain optimal performance layout design scheme,the layout positioning model representation method based on artificial potential field was proposed.And by creating the model of the attraction potential field,the repulsion potential fields and the total potential superposition field under different influence factors,the layout positioning design problem was transformed into searching for potential extreme position in artificial potential field.Then the digital potential field of the layout environment state model was obtained by using grid model to describe the layout space environment information.The layout positioning algorithm model based on improved continuous ant colony algorithm was presented to obtain layout positioning scheme.The comparison results of layout design scheme solved in several algorithms reveal the effectiveness of the proposed artificial layout potential field model and optimization algorithm.
