  First, when the parts are determined for all spaces, the operation terminal 20 next checks the security level of the parts selected for placement in the area as the security area. Then, the area is color-coded according to the result.

  Here, for example, when an entry / exit management device using biometric authentication is selected for placement at the entrance / exit of an area, the security level of the entry / exit management device is high, that is, level 3, so that the arranged area is predetermined. The color is changed to, for example, blue. Thereby, the person in charge of the layout creation department can easily confirm the security level of the area visually.

  Next, the operation terminal 20 checks the security level of the part selected for placement in the area as the security area, and calculates a difference from the security level, that is, compares the security level with the security level. I do. As a result, when the security level is higher than the security level, an alarm message is displayed on the screen of the display unit 22 and the part is blinked.

  For example, when an entry / exit management device that uses a magnetic card is selected for placement at the entrance / exit of an area, the security level of the entry / exit management device is at a level, that is, level 2, so that the arranged area has a predetermined color For example, it is painted yellow. On the other hand, when a cabinet for storing confidential documents for selection in the area is selected, the security level is high, that is, level 3. In this case, since the security level is higher than the security level, the operation terminal 20 displays an alarm message on the screen of the display unit 22 and blinks the cabinet design to give a warning to the person in charge.

  When the alarm message is displayed, the person in charge corrects the part and replaces it with an entry / exit management device with a high security level, or changes to an arrangement of equipment with a low security level.

  For example, when the entry / exit management device is changed to an entry / exit management device using biometric authentication, the area is repainted in blue and the difference becomes 0, so that the display of the alarm message and the blinking of the parts are stopped.

Next, a flowchart will be described.
Step S21: The security level of the part is checked, and the area is color-coded according to the result.
Step S22: The security level is compared with the security level. If the security level is higher than the security level, the process proceeds to step S23. If the security level is not higher than the security level, the process ends.
Step S23 An alarm message is displayed on the screen of the display unit 22, and the part is blinked.
Step S24: The part is corrected and the process is terminated.
