A COMPOSITE INDEX FOR THE EVALUATION OF STANDARDIZATION LEVEL OF MECHANIC SYSTEMS
Standardization of components of assemblies is important in both reverse engineering and design. In design, it leads to cost reduction by minimizing the number of items designed from scratch and the number of new manufacturing processes. The work presented introduces a composite standardization index by combining a commonality index and an absolute standardization index. The index counts the populations of common parts in assemblies and the degree of absolute conformance of those parts with engineering standards. It is a tool that represents reliably the level of standardization of a system.
