Plan making system, and plan making device and plan making method used in plan making system

Abstract

A plan making system, and a plan making device and a plan making method used in the same, for making an evaluated plan in consideration of the relationship between the mitigation amount of a restriction and a plan evaluation value for a plan requiring mitigation of the restriction condition. The plan making device is provided with a processing device and a storage device and is used for making a production plan; the processing device includes: a plan making part that creates a plan on the basis of order information scheduled by an input plan, constraint conditions generated from device information, and an evaluation function; a restriction mitigation part that mitigates violation of restriction when violation of the restriction condition; the restriction mitigation part specifies restrictions associated with violation of restrictions, generates mitigation patterns, extracts, for each mitigation pattern, a relationship between an mitigation amount and an evaluation value in an evaluation function and an mitigation amount application frequency from history data, and selects an mitigation amount on the basis of the relationship between the mitigation amount and the evaluation value and the mitigation amount application frequency; a plan making part that makes a plan on the basis of the amount of mitigation for each mitigation pattern that has been generated, evaluates the plan with an evaluation function, and uses a better-evaluated plan.

Description

Technical field [0001] The present invention relates plans to take into account the constraints of the ease of development of the system. Background technique [0002] When planning the system, carry out planning, real-world problems in a larger number of constraints, it is difficult to satisfy all of the constraints. Therefore, in the planning system, based on the development of an efficient plan to ease constraints in the case does not meet all of the constraints to become a general issue. [0003] As background art of the present technical field, Patent Document 1. Disclosed in Patent Document 1 has a distribution plan way to specify an article distribution planning system comprising: a storage unit, holding constraints established distribution plan, and cost information for calculation of the distribution cost based on distribution plan to use; distribution development and way cost calculation unit, in order to satisfy the constraints of developing these constraints distribut...

AI Technical Summary

Problems solved by technology

[0002] In the planning system, when planning, there are many constraints in practical problems, and it is difficult to meet all the constraints

Therefore, in the planning system, when all the constraints are not satisfied, planning based on efficient constraint relaxation is a general problem.
