Production planning apparatus and production planning method
First Claim
1. A production planning apparatus, comprising:
- a storage unit configured to store;
actual performance information on a resource required for production;
a planning master including a plan of a resource required for work of the production, the plan of the resource including a percent defective of an item specifying a product or a part of the product to be produced under the production; and
a planning parameter including a variable required for a production plan, the planning parameter including information specifying a safety stock which is information specifying a safety stock quantity of the item, the safety stock being set in preparation for deterioration of the percent defective of the item;
a parameter generation processing unit configured to change the plan of the resource required for the work including the percent defective of the item, which is included in the planning master, based on a difference between the plan of the resource, which is included in the planning master, and actual performance of the resource required for the production, which is included in the actual performance information, and change the planning parameter including the information specifying the safety stock based on how greatly the planning master is changed; and
a production plan processing unit configured to calculate a production plan that uses the planning master and the planning parameter.

9. A production planning apparatus, comprising:
-
a parameter generation processing unit configured to; receive, from an external apparatus, actual performance information on a resource required for production and a planning master including a plan of a resource required for work of the production, the plan of the resource including a percent defective of an item specifying a product or a part of the product to be produced under the production; change the plan of the resource required for the work including the percent defective of the item, which is included in the planning master, based on a difference between the plan of the resource, which is included in the planning master, and actual performance of the resource required for the production, which is included in the actual performance information; and calculate a planning parameter including a variable required for a production plan based on how greatly the planning master is changed, the planning parameter including information specifying a safety stock which is information specifying a safety stock quantity of the item, the safety stock being set in preparation for deterioration of the percent defective of the item; and an output unit configured to transmit the planning master and the planning parameter to the external apparatus. - View Dependent Claims (10, 11, 12, 13, 14)

15. A production planning method for causing a computer to execute a procedure for planning production,
the computer comprising: -
a storage unit configured to store; actual performance information on a resource required for production; a planning master including a plan of a resource required for work of the production, the plan of the resource including a percent defective of an item specifying a product or a part of the product to be produced under the production; and a planning parameter including a variable required for a production plan, the planning parameter including information specifying a safety stock which is information specifying a safety stock quantity of the item, the safety stock being set in preparation for deterioration of the percent defective of the item; and a control unit, the production planning method comprising executing, by the control unit; a parameter generation processing step of changing the plan of the resource required for the work including the percent defective of the item, which is included in the planning master, based on a difference between the plan of the resource, which is included in the planning master, and actual performance of the resource required for the production, which is included in the actual performance information, and changing the planning parameter including the information specifying the safety stock based on how greatly the planning master is changed; and a production plan processing step of calculating a production plan that uses the planning master and the planning parameter. - View Dependent Claims (16, 17, 18, 19, 20)
