Abstract [en]

In response to the increasingly competitive global market, there is a growing interest in design optimization. Being able to include aspects of socio-ecological sustainability in product design should aid companies to both improve current competitiveness and to identify viable long-term investment paths and new business opportunities in the evolving sustainability-driven market. A case study of a water jet cutting machine is used to illustrate a new iterative optimization procedure that combines a technical assessment with a sustainability assessment. Sustainability assessment methods/tools are first used to identify prominent sustainability problems from present-day flows and practices (“societal indicators”) and to generate ideas of long-term solutions and visions. Based on this, preliminary ideas about likely desirable changes in machine properties are obtained. Technical investigations are then performed to assess if/how these particularly desirable changes in machine properties could in principle be realized through changes in design variables. After that, obtainable changes are fed back to a new and more refined sustainability assessment to find out the societal implications of these changes. This may in turn result in other desirable design changes, which may call for a new and more refined technical assessment, etcetera. The experience from the case study indicates that the suggested integrated and iterative working procedure should be able to add information about socio-ecological impacts of product properties and influence design criteria used in prioritisation situations during product development.

Abstract [sv]

På den konkurrensinriktade globala marknaden blir konstruktionsoptimering alltmer intressant. Att kunna inkludera socio-ekologiska hållbarhetsaspekter i produktutveckling borde hjälpa företag både att förbättra både kortsiktig konkurrenskraft och att identifiera långsiktiga affärsmöjligheter på den framväxande hållbarhetsdrivna marknaden. En fallstudie över en vattenskärningsmaskin används för att illustrera en nytt iterativt optimerande arbetssätt som kombinerar både tekniska och hållbarhetsmässiga analyser. Erfarenheterna från fallstudien pekar på att det föreslagna iterativa arbetssättet lyckades inkludera information om produktens socio-ekologiska hållbarhetseffekter. Konstruktionskriterier kunde också påverkas på ett konsekevent sätt och därmed styra produkutveklingen i en mer hållber riktning. Nyckelord: produktutvekling, optimering, hållbarhetsanalys, simulering, vattenskärning
