Abstract
The decisions made during product development (PD) lock in 70–80% of the total product cost, and the quality of the product is also largely fixed. Therefore, decisions which are taken during the PD process have a great influence on product life cycle cost, quality and sustainability. The most important point of the PD process where trade-offs are made is in the concept phase when defining design specifications based on customer requirements. Developing a model to support trade-offs for sustainable PD is a significant concern for designers. This research attempts to consider these features simultaneously to make trade-offs between environmental issues and other customer requirements to select the best design specifications on their basis. In this research, sustainability is considered as a customer requirement, which then is translated into design specifications. Sustainable design is treated as an optimization problem to maximize value-added activities while minimizing environmental effects. A scoring model is defined to model sustainability, quality and cost in the PD process in order to find the optimum level of their combination therefore.
