摘要: The life cycle design framework developed at the University of Michigan was applied by AUiedSignal to improve manufacture, use, and end-of-lie management automobile oil filters. Three filter designs were investigated: a conventional spin-on fdter which is singleuse producr cartridge consisting reusable housing replacement Camidge, cleanable uses element Environmental, cost, performance, legal requirements using matrix tool tradmffs between these studied. These criteria are presented along with results from an analysis user costs simplified energy analysis. Key elements framework, based on systems analysis, multiobjective multistakeholder panicipation, also described
