Abstract: PURPOSE:To reduce a processing burden for the allocation decision of the combination of plural jobs and resources by judging a choice between two things that is which resource fits much more to a restriction condition between retrieved resources and newly storing the resource which fits much more to the restriction condition in a candidate storage part. CONSTITUTION:For deciding allocation, one suitable combination of the job and the resource is mentioned at random from those in the candidate storage part 5. Since nothing is stored in the candidate storage part 5 at first, one combination is mentioned at random. Then, a prescribed condition is inspected in a condition inspection part 3 as to the resource of the combination. When it does not fit the condition, the combination of the job and the resource is eliminated. The combination satisfying the prescribed condition is stored in the candidate storage part 5 as the allocation candidate. Then, one combination fitted next is mentioned and is compared. In such a case, the candidate which remains last becomes the optimum candidate and the combination is decided, whereby actual allocation work is executed. Thus, the optimum candidate can be decided in short time.
