DESIGN PART REUSING METHOD IN CONFIGURATION TOOL

In a design part reusing method in a configuration tool, a reference link defining an alias relationship between one functional object and another functional object is set. The reference link is explicitly displayed on a display between icons respectively representing one functional object and another functional object. One functional object and another functional object are set as aliases on the basis of the reference link. The reference link is explicitly disconnected to cancel the alias relationship on the display.
