The level of standardization of products and systems affects production process and the cost for their operation and maintenance. In reverse engineering and design, the systematic consideration of standards leads to better evaluation and efficient synthesis of parts and assemblies. Taking into account standardization during design leads to systems with better operational characteristics, high quality and low cost. The establishment of metrics for estimating the standardization level of systems can provide valuable tools for analytic and synthetic engineering processes. The present study introduces such a metrics that is based on system analysis and decomposition into hierarchical structures of parts and assemblies. Procedures search exhaustively that structures and perform calculations of standardization indices. A PC-based platform implements the proposed method and provides estimations of standardization levels and multiple graphical outputs that visualize the obtained results. Then the designer may inspect the standardization level of parts, components and assemblies and proceed with necessary modifications. The method is exemplified with a study of a robot base subassembly.
