CALCULATION APPARATUS, PROGRAM, CALCULATION SYSTEM AND CALCULATION METHOD FOR DRAFTING PRODUCTION PLAN

摘要

PROBLEM TO BE SOLVED: To provide a technique capable of drafting a flexible production plan matching the circumstances of the production demand.

SOLUTION: An available production quantity calculation part for implementing material requirements planning for computing an available production quantity and a production availability date for production request information having at least one production request specifying a requested production quantity; a requested production date and a priority level for a type of product computes the available production quantity and production availability date as delaying the requested production date by a plurality of methods, if determining that the requested production quantity in one production request cannot be produced by the requested production date in the one production request. A display information generation part then creates image data that list the available production quantities and the production availability dates computed by the plurality of methods.
