Abstract
The number and the attributes of custom parts affect significantly the standardization level of mechanical systems and determine their functional characteristics and their value. In the present study, a part classification scheme and a calculation procedure are introduced that enable systematic adaptation and standardization of custom parts during in-enterprise design and manufacturing processes. The level of standardization of the mechanical system under consideration is evaluated via metrics represented by a composite standardization index derived from the combination of two (2) partial indices, namely an index that represents the absolute attribute-based standardization of each part of the system and a second index that represents the degree of commonality for different parts and/or assemblies for the same system. The proposed approach leads to a more reliable evaluation of standardization levels by taking into account all in- and out-of-enterprise available standard resources and provides a framework that promotes design-for standardization processes. Additionally, it contributes towards more efficient and functional products and decreases design and manufacturing costs.
