摘要

The increasing number of green consumers in global industry has formed a distinctive economic niche that has not been fully optimized by business actors. The existence of this market niche becomes a challenge for the industry to win the global market through quality design and competitive prices and products that have a good impact on the environment. This research explained product criteria as a basic consideration for the company in developing or creating new products that meet the needs of this specific consumer in the furniture industry. It needs a product design model that can integrate quality, cost and environmental criteria. One of the methods in designing product concept that can integrate the needs of the green consumer in fulfilling the aspects of quality, cost and environment is Green QFD method. Criteria of product quality are determined by looking for Quality index of consumer needs through technical requirements with the House of Quality matrix. The criteria of cost are analyzed by investigating internal and external costs by utilizing the House of Cost matrix. Meanwhile, the environmental criteria are determined based on the environmental index by Eco-Indicator method through Green House matrix. AHP method is used to determine alternative of the best design product choices among the criteria that have been produced by the Green QFD method. The integration of the Green QFD and AHP method provides a holistic outcome of how the design of industrial products is structured and analyzed through the quality, cost and environmental criteria. The result shows that cost factors are the most influential criteria in compared with the quality and environmental criteria.
