An apparatus and method for quickly retrieving and outputting assemblies or subassemblies similar to a target assembly or subassembly for similar determination are provided. Data concerning assemblies, and the subassemblies and parts contained in the assemblies is retrieved from a product structure data storage device; hierarchical structures of the assemblies and subassemblies are detected; similarity is calculated for all the combinations of the assemblies and subassemblies based on the detected hierarchical structures; and the hierarchical structures of the assemblies and subassemblies and similarity for each combination of assemblies and subassemblies are stored in a similar data storage device. When a target assembly or subassembly for similarity determination is inputted via an input device, assemblies or subassemblies similar to the target assembly or subassembly are retrieved from the similar data storage device, and the retrieved assemblies and subassemblies are displayed on a display device.
