Toward a Decision Tool for Eco-Design Strategy Selection of Aircraft Manufacturers Considering Stakeholders Value Network 2013-01-2278

This paper introduces a novel approach in order to compare different eco design practices considering the value network of stakeholders. The proposed decision tool framework in this study helps manufactures in early stage of design to select a portfolio of eco design techniques to maximize the value perceived by all stakeholders in a dual life cycle approach including the business product life cycle as well as physical life cycle. A portfolio selection approach has been used to maximize the network value of stakeholders considering the life cycle cost and risk of techniques while satisfying the diversity of allocation resources on eco design practices based on strategic objectives of manufacturers. The dynamic characteristic of stakeholder's network as the result of implementing the different eco design techniques has also been considered in order to evaluate the synergy in stakeholder's network. Therefore the developed framework in this study is an effective way to assist the decision makers in prioritizing eco-design techniques and managing an optimal portfolio of them. As an application of developed model, we proposed a guideline for Aircraft manufacturers in order to select the best set of design for end of life techniques considering all stakeholder's needs and expectations. This guideline can help aircraft manufacturer to compare the variety of eco practices in three categories including material usage, providing information and manual and design for 3R (reducing, re-using and recycling) considering pertinent impacts to all stakeholders in addition to business priority in life cycle perspective.
