Information processing device and program

An information processing device for supporting construction of a network, the network comprising a plurality of units, the plurality of units comprising:

• an electric power supply unit coupled to ones of the plurality of units connected downstream from the electric power supply unit;
• and
• a connected unit, wherein each of at least some of the ones of the plurality of units connected downstream from the electric power supply unit comprises the connected unit, each of the connected units connected downstream from the electric power supply unit being supplied with electric power from the electric power supply unit by an upstream one of the plurality of units and each of the connected units supply remaining electric power to a connected downstream respective one of the connected units;
• the information processing device comprising:
• a memory portion storing an amount of electric power consumed by each of the connected units and an amount of electric power suppliable by the electric power supply unit;
• a display;
• and
• a processor configured with a program to perform operations comprising:
• operation as a configuration portion that virtually configures, in response to an input operation comprising one of:
• addition of a unit to the plurality of units;
• and removal of a unit from the plurality of units, the network including the connected units and the electric power supply unit to produce a virtually configured network comprising a virtual configuration of the plurality of units in the network;
• operation as a determination portion that determines, for each one of the plurality of units in the virtually configured network, an overage or a shortage of electric power to be supplied to the respective one of the plurality of units, on a basis of the amount of electric power consumed by the respective one of the plurality of units subtracted from the electric power suppliable by the connected unit immediately upstream from the respective one of the plurality of units to produce a determination result;
• and
• operation as a display portion that displays on the display, for each one of the plurality of units in the virtually configured network, a state of the electric power supply that indicates the overage or the shortage of electric power for the respective one of the plurality of units in the virtually configured network, based on the determination result wherein,
• the processor is configured with the program to perform operations such that operation as the determination portion comprises operation as the determination portion that determines the electric power suppliable by the connected unit immediately upstream from the respective one of the plurality of units in the virtually configured network based on a sum of the amount of electric power consumed by each of the connected units upstream from the respective one of the plurality of units subtracted from the amount of electric power suppliable by the electric power supply unit.
