Abstract

This invention relates to a production system for retail goods which is intended for timely collection of accurate sales information from retail outlets and flexible production of goods in accordance with the same information, and comprises a retail sales information collecting means, a production quantity setting means for determining a production quantity according to the information so collected, a directing means for directing the preparation and production of raw materials according to the determined production quantity, and a production means for producing the determined production quantity according to a direction to produce. Also provided is a raw materials ordering system, which determines production quantities of raw materials in accordance with production plans for ensuring flexible production of the products without the disadvantage of carrying excessive inventories and for economical and efficient control and supply of raw materials. As such, the system comprises an order quantity determining means for setting or modifying daily required quantities of raw materials in response to setting or modification of daily production plans and determining order quantities according to raw material attributes, inventories, order backlogs, in-process order quantities and the required quantities of raw materials and a data input processing means for modifying the raw material inventory quantities upon receipt of raw material acceptance information. Furthermore, another type of the raw material ordering system disclosed in this application can be employed for those raw materials that require processing after placement of an order.
