<P>PROBLEM TO BE SOLVED: To provide a merchandise purchase cycle management system for detecting merchandise which has exceeded the period of purchase, among the pieces of merchandise which should be purchased periodically, and reporting it to customers. <P>SOLUTION: When a customer purchases merchandise X, a store controller 1 records the date of purchase and the merchandise X purchased into a history file 5 for each customer. At the closing time, the store controller 1 reads the maximum permissible number of dates for the merchandise X from a specific merchandise table 4 and detects the date of purchase of the merchandise X by the customer from the history file 5. The store controller 1 then checks purchase date data to see if the purchase of the merchandise X has periodicity. If there is periodicity, the store controller 1 calculates the elapsed number of days from the last date of purchase of the merchandise X to this day. Then the store controller compares the period of purchase plus the maximum permissible number of days with the elapsed number of days; if the elapsed number of days is greater, the controller determines that the period of purchase of the merchandise X has been exceeded, and creates direct mail to be sent to each customer. <P>COPYRIGHT: (C)2004,JPO |
