METHOD AND DEVICE FOR PLAN CORRECTION

摘要

PROBLEM TO BE SOLVED: To correct a plan so that the correction is suppressed locally by finding an optimum solution which meets essential restrictions as to one partial plan to the utmost and further finding an optimum solution which meets target restriction based upon the condition that a previous plan is not corrected as much as possible when the essential restrictions are met. SOLUTION: A partial plan correction part 60 when reallocating remaining operation styles to remaining resources in response to a change of the operation style of a resource at a specific date performs the reallocation of the date by referring to restriction conditions 34 and a rule base 35 so that the cost in case of a violation of the restriction conditions is minimum, and generates a corrected plan 32. A correction path search part 40 decides whether or not the essential restriction conditions are met and repeats the process of the partial correction part 60 when not. If a sufficient solution can not be obtained even by making a search as to a specific number of succeeding days, that is reported to a plan adjustment part 80, which supports the relaxation of the restrictions.
