Abstract
A layout design assisting system operates in the following steps. A drawing of a layout area for installing a plurality of layout objects is displayed on a display unit. The operator specifies one of the displayed layout objects. Another layout object which interferes with the specified layout object is found in the layout area. An economical loss imposed on the specified layout object attributable to the other layout object is evaluated. Examination is conducted as to whether or not the other layout object can be relocated so that it does not interfere with the specified layout object. The specified layout object, the other layout object, the economical loss and the examination result are displayed on the display unit.
