Demand-production scheme planning apparatus, and storage medium

A demand-supply scheme planning method comprising:

• storing first data regarding a cost and a time that are needed between a purchase step and a supply step of each demand-supply step of a supply chain in which a plurality of demand-supply steps each having an order receipt step, an order placement step, a purchase step, and a supply step that are related to a commodity;
• inputting an order receipt scheme of a demand-supply step of the plurality of steps that is located at a supply-side terminal of the supply chain;
• determining scheme data regarding the order receipt step, the order placement step, the purchase step, and the supply step of each of the plurality of demand-supply steps based on the order receipt scheme inputted by sequentially changing a variable parameter;
• calculating a profitability index of the supply chain based on the scheme data determined and the first data;
• changing a value of the variable parameter;
• and
• setting, as a demand-supply scheme, scheme data that maximizes the profitability index calculated, of the scheme data determined using the variable parameter.

• second means for inputting stock records of the product and the member of each demand-supply step of the supply chain;
• third means for inputting an order receipt scheme of the product of a demand-supply step located at a shipment-side terminal of the supply chain;
• fourth means for calculating a profitability index of the supply chain based on scheme data regarding order receipt, order placement, purchase and shipment of each demand-supply step, and the first and second data stored by the first means;
• and
• fifth means for setting the scheme data regarding order receipt, order placement, purchase and shipment of each demand-supply step so as to increase the profitability index, based on the order receipt scheme inputted and the stock record inputted, and the third data stored by the first means.

• and
• setting the scheme data regarding order receipt, order placement, purchase and shipment of each demand-supply step so as to increase the profitability index, based on the order receipt scheme inputted and the stock record inputted, and the third data stored by the first means.

A scheme planning system that plans a sales scheme or a production scheme of each of a plurality of locations connected in accordance with a material flow, through exchange of information regarding a number of the material flow between scheme planning apparatuses that are disposed respectively in the locations, the scheme planning system comprising:

• a plurality of scheme planning apparatus comprising:
• first means for planning an order receipt scheme by determining a number of articles requested of a location concerned from a post-location located at a later stage in a material flow path, as a scheme number of order receipt;
• second means for planning a sales scheme or a production scheme by determining a scheme number of sales/production of the location concerned based on the scheme number of order receipt from the order receipt scheme processing means;
• third means for planning an order placement scheme by determining a number of articles requested of a pre-location located at an earlier stage in the material flow path, as a scheme number of order placement, in order to realize the sales/production scheme planned by the second means;
• fourth means for planning a shipment scheme by determining a number of articles shipped from the step concerned to the post-step, as a scheme number of shipment;
• and
• fifth means for planning a purchase scheme by determining a number of purchase sent from the pre-location to the location concerned, as a scheme number of purchase,
• wherein the first, second, third, fourth and fifth means determine the scheme number in accordance with a restricting condition that is set individually for the first, second, third, fourth and fifth means regarding at least sales, production and material flow.

A scheme planning method for planning a sales scheme or a production scheme of each of a plurality of locations connected in accordance with a material flow, through exchange of information regarding a number of the material flow between the locations, the scheme planning method comprising the steps of:

• (A) determining a number of articles requested of a location concerned from a post-location located at a later stage in a material flow path, as a scheme number of order receipt;
• (B) planning a sales scheme or a production scheme by determining a scheme number of sales/production of the location concerned based on the scheme number of order receipt from the (A)step;
• (C) determining a number of articles requested of a pre-location located at an earlier stage in the material flow path, as a scheme number of order placement, in order to realize the sales scheme or the production scheme planned by the (B) step;
• (D) planning the sales/production scheme of each location sequentially in a direction from a post-location to a pre-location by receiving the scheme number of order receipt from an immediate post-location, and giving the scheme number of order placement to an immediate pre-location.
