<P>PROBLEM TO BE SOLVED: To prevent the loss of chances to sell a beverage by temperature change by enabling appropriate setting of a temperature for switching the beverage to hot or cold. <P>SOLUTION: A switching condition analysis part of the sales information analysis server device performs analysis of switching conditions in response to an instruction from, for example, a manager of the server device. Concretely, the switching condition analysis part analyzes, based on sales information stored in a sales information storage part, relation of each sales (number) of hot and cold with air temperature at purchasing for each beverage (e.g., a beverage A) as shown in Fig.2, and detects an air temperature which triggers switching between hot and cold (e.g., air temperature at which the sales numbers of hot and cold are estimated to be equal) as a temperature condition which is one of switching conditions. <P>COPYRIGHT: (C)2008,JPO&INPIT |
