Abstract

A machine management system improves flexibility in control of an apparatus and installation of an additional apparatus. A plurality of refrigerators sends operational information to a virtual machine constructor. The virtual machine constructor constructs virtual machines corresponding to the refrigerators using the received information, and holds the virtual machines therein. Each time the virtual machine constructor receives new information from the refrigerators, it updates the virtual machines. Controllers receive and hold virtual machines from the virtual machine constructor. The controllers cause one of the virtual machines to be selected and displayed in response to a user'"'"'s request.
