PROBLEM TO BE SOLVED: To improve the reliability of an interference check result in the case of executing interference check in one aspect.SOLUTION: An interference check execution part (12) verifies the interference of mutual components. The interference check execution part (12) executes interference check to an object subordinate to the most significant assembly designated by an assembly designation part (20) by an individual verification part (22), and stores the interference check result in association with the assembly in a storage part (16) by an information writing part (28). An interference check result output part (14) acquires interference result information associated with the assembly, and determines whether or not the acquired interference result information is valid by comparing the latest edition time with an edition time in the case of checking interference by a validity verification part (32). Therefore, it is possible to improve the reliability of the interference check result on the basis of a difference between the edition time. |
