AUTOMATIC ISSUE SYSTEM FOR REPEAT ORDER RECEPTION LEDGER

摘要

PURPOSE:To predict the movement of demand on an article which is repeatedly ordered and to set an order reception period and a manufacture input period according to the movement of demand. CONSTITUTION:A character-display graph which show the ratio of the delivery quantities of respective months is generated and periodic articles are selected according to the graph. Then the demand quantity of each of the article is estimated from the transition of the delivery quantity of past three months (S1), and the out-of-stock period of inventories is predicted by dividing the volume of inventories by the demand quantity (S2). Then a next-time order reception period for preventing a backlog from being exceeded is calculated by subtracting a standard lead time from the period where the backlog is exceeded and the manufacture input period for unmanufactured articles for preventing an out-of-stock state is calculated by subtracting the standard lead time from the out-of-stock period (S3). Then information on the set next-time order reception period is sent to the sales department for repeat order reception billing and the unmanufactured article input period is sent to the factory (S4).
