It is imperative to take into account the measurement and verification of products and processes during early design, due to current challenge induced by the increasing use of large and complex assemblies and fabrications in the aerospace, power generation and automotive industries. A theoretical framework for the creation of Metrology Process Models (MPMs) has been presented by Maropoulos et al. (2008). This paper presents the approach of implementing the first stage of the framework by analysing the measurability of key features according to their dimensions and tolerances. A prototype system of early design measurability analysis has been developed consisting of; (i) a database that stores physical capabilities and accuracy capabilities of different Large Volume Measurement systems, (ii) a search engine that handles the selection of measurement systems for specific design features based on predefined decision rules and algorithms and (iii) an interface between design and MPM which imports the key features from design to the MPM and feeds back to designers the applicable measurement systems. The MPM selection process includes a variety of parameters such as physical range capability, accuracy, measurement cost and technology readiness level and the feedback to the design team allows early design to consider the verification of large and complex products and assemblies.
