Abstract: To overcome the deficiency of traditional reuse utility measurement method, which was based on the number of reused physical end-items in product assembly, a reuse utility evaluation system based on cost, time and quality was put forward. Relevant reuse cost structure was studied, which was composed of two parts：reuse-oriented development cost (modularization cost, standardization cost, documentation cost, cataloging cost, data maintenance cost) and reuse-based design cost (retrieval cost, modification cost, integration cost, revalidation cost). A quantitative mathematical model for component reuse utility was proposed, and computation method for reuse utility on product level was also provided. Finally, an example for automotive parts design reuse was given.

Key words: product development, design reuse, reuse utility, quantitative model
