In addition, as shown in FIG. 5, when displaying the distribution cost, it is also desirable to display the change rate of the distribution cost (a ratio indicating the amount of change from the current distribution cost) at the same time.

  Furthermore, the control means 100 is provided with a sorting means for sorting (rearranging) the record information displayed on the display means 150 in units of record information. For example, if the distribution cost is used as sort key information, the layout creator can easily identify the layout information with the lowest distribution cost from the information obtained from the display means 150.

  The next step S180 is a step in which layout information desired by the layout creator is selected from the extracted post-relocation layout information. In the layout support system 10 according to the first embodiment, information for selecting record information from the record information 151 displayed on the display unit 150 is input by the input unit 160 and corresponds to the selected record information. The layout information to be stored is stored in the information storage unit 110 by the control unit 100.

  In the first embodiment, the facility to be relocated is selected based on the facility relocation information 113e in the facility information 113. However, the information (for example, facility number information 113b) for specifying the facility to be relocated is input from the input unit 160. By doing so, the equipment to be relocated may be selected. In this case, step S130 in FIG. 2 is a step for inputting information (for example, equipment number information 113b) for specifying the facility to be transferred from the input means 160, and step S140 is a step for transferring the selected facility. This is a step of generating layout information.
