A decision support framework for developing ecodesign at conceptual design phase
Abstract:
The objective of this research is to propose a decision support framework for
advance development Ecodesign concept based upon Concurrent Engineering. Series
of tools have been performed for its methodology; Streamlined Life Cycle
Assessment, Quality Function Deployment for Environment, Patent Mapping, Design
for Life Cycle Thinking, Theory of Inventive Problem Solving, Analytic Network
Process, and Distance-to-Target. The contribution of this research lies in the decision
support methodology for integrating in a simple model using Analytic Hierarchy
Process (for a hierarchy decision making design without feedback from lower to
higher level) and a complex model using Analytic Network Process (for network
decision making design with dependence amongst alternatives or criteria and
feedback from lower to higher level) and the distance to target method based upon
concurrent engineering concept in order to quantify a single score Ecodesign concept
indicators and ease the new product development process to become more eco
effective than the baseline product. With this methodology, all stakeholders concerns
throughout the whole product life cycle phase have been integrated in the Ecodesign
process. One highlight of this framework is that the model can reduce bias and ease
the decision making process as well as helping in presenting the new idea to
stakeholders.
In order to examine the verification a new decision support framework, five
electrical and electronics pilot factories take account of the current situation and
obstacles. Then, the experiment with a printer design factory has been conducted to
test, improve, and verify a new decision support framework. Both case studies from a
Hermetic Compressor factory and an Air Conditioner factory are finally carried out to
validate a new decision support framework. The results depict that it can reduce
design cost 50%, time 50%, and enhance the efficiency from 3 to 36% of redesigned
product comparing with the baseline product. The publications, recommendations,
limitations and further research are also presented.
