Claims

A production planning device that calculates an allocation amount that allocates excess demand that exceeds production capacity during a high demand period to a low demand period in a production plan of a plurality of products or product groups,
A dividing unit that divides the demand forecast amount for each product or product group into a plurality of demand forecast amounts for each attribute based on attributes relating to the product or product group;
An allocation amount calculating means for calculating an allocation amount for each product or product group corresponding to the excess demand based on one of the demand forecast amounts for each attribute divided by the dividing means. Planning equipment.

The production planning apparatus according to claim 1, wherein the attribute is a statistical variation amount for each product or product group.

Based on the attribute, which is a statistical fluctuation amount for each product or product group, the dividing means includes a certain demand forecast amount for which the demand is estimated to be certain, and a variable demand for which the demand is estimated to be variable. The demand forecast amount is divided into two types of forecast demand by attribute of forecast amount,
The said allocation amount calculation means calculates the said allocation amount according to the said product or product group for the said excess demand based on the said certain demand forecast amount which the said division means divided | segmented. Production planning equipment.

4. The production planning apparatus according to claim 2, wherein the statistical fluctuation amount is obtained based on a variance or deviation of a difference between a demand forecast amount and a demand record of each product or product group in the past. .

The allocated amount calculating means obtains a ratio for each product or product group based on one or more addition values of the attribute-specific demand forecast quantities divided by the dividing means, and determines the excess demand component according to the ratio. 5. The production planning apparatus according to claim 1, wherein an allocation amount for each product or product group is calculated.

Setting means for prompting the user to set a minimum demand forecast request for requesting a minimum demand forecast for each product or product group or a maximum demand forecast request for requesting a maximum demand;
When the minimum demand forecast request is set by the user, a second demand forecast amount for each product or product group is calculated using the certain demand forecast amount, and the maximum demand forecast is calculated by the user. When a request is set, a demand prediction unit that calculates a second demand forecast amount for each product or product group by adding the variable demand forecast amount to the demand forecast amount;
An excess demand component calculating means for calculating a second excess demand component based on the second demand forecast amount calculated by the demand prediction device;
The allocated amount calculation means is based on the second demand prediction amount calculated by the demand prediction means, and the product or product group is configured for the second excess demand calculated by the excess demand calculation means. The production planning apparatus according to claim 3 or 4, wherein an allocation amount is calculated.

2. A production plan generation unit that generates a production plan for each product or product group based on the allocation amount calculated by the allocation amount calculation unit and the demand forecast amount. The production planning device according to claim 6.

A production planning method for calculating an allocation amount for allocating an excess demand amount exceeding a production capacity during a high demand period in a low demand period in a production plan of a plurality of products or product groups,
Dividing the demand forecast amount for each product or product group into a plurality of demand forecast amounts for each attribute based on attributes relating to the product or product group;
And a second step of calculating an allocation amount for each product or product group corresponding to the excess demand based on one of the demand forecast amounts for each attribute divided in the first step. Production planning method.

9. The production planning method according to claim 8, wherein the attribute is a statistical fluctuation amount for each product or product group.

In the first step, based on the attribute, which is a statistical fluctuation amount for each product or product group, a certain demand forecast amount for which the demand is estimated to be certain, and the demand is estimated to be variable. The demand forecast amount is divided into two types of attribute demand forecast amounts of variable demand forecast amount,
The second step calculates the allocated amount for each product or product group corresponding to the excess demand based on the certain demand forecast amount divided in the first step. The production planning method described in 1.

This is a computer-readable recording medium that records a program for a production planning device that calculates an allocation amount that allocates excess demand that exceeds production capacity during a high demand period to a low demand period in a production plan for multiple products or product groups. And
Dividing the demand forecast amount for each product or product group into a plurality of demand forecast amounts for each attribute based on attributes relating to the product or product group;
Causing the production planning device to execute a second step of calculating an allocation amount for each product or product group corresponding to the excess demand based on one of the attribute-specific demand forecast amounts divided in the first step. A computer-readable recording medium on which a program for recording is recorded.

A program for a production planning device that calculates an allocation amount that allocates excess demand that exceeds production capacity during a high demand period to a low demand period in a production plan for multiple products or product groups,
Dividing the demand forecast amount for each product or product group into a plurality of demand forecast amounts for each attribute based on attributes relating to the product or product group;
Causing the production planning device to execute a second step of calculating an allocation amount for each product or product group corresponding to the excess demand based on one of the attribute-specific demand forecast amounts divided in the first step. Program for.
