Computer system and method for calculating limit number of displayed commodities

A computer system comprising:

• an input unit for inputting information;
• a display unit for displaying the information;
• a space-size storing unit for storing, in association with a space code for specifying a display space, size information of the display space;
• a commodity-size storing unit for storing, in association with a commodity code for specifying a commodity, size information of the commodity;
• and
• an information processing unit configured to execute:
• processing for dividing space width of a display space, the space width of a display space being specified by a space code input from the input unit and being acquired from the space-size storing unit, by commodity width of a commodity, the commodity width of a commodity being specified by a commodity code input from the input unit and being acquired from the commodity-size storing unit, to calculate a width direction number of commodities that can be displayed in a width direction of the display space;
• processing for dividing space depth of the display space, the space depth of the display space being specified by the input space code and being acquired from the space-size storing unit, by commodity depth of the commodity, the commodity depth of the commodity being specified by the input commodity code and being acquired from the commodity-size storing unit, to calculate a depth direction number of commodities that can be displayed in a depth direction of the display space;
• processing for multiplying together the width direction number of commodities and the depth direction number of commodities to calculate a limit number of displayed commodities;
• and
• processing for displaying the limit number of displayed commodities on the display unit.
