  • Publication number: 20220215449
    Abstract: In a parts configuration plan generation device, a concretization processing unit (first concretization unit) concretizes an “abstract configuration” by using a first concretization pattern, and thereby generates a “base parts configuration”. A concretization processing unit (second concretization unit) applies a second concretization pattern to the base parts configuration and concretizes a parts item contained in the base parts configuration, and thereby generates a “candidate parts configuration”. An output unit outputs, as a “parts configuration plan”, the candidate parts configuration where concretization is done and satisfying a condition to be satisfied by a device to be built.
