Application of fuzzy logic-based environmental conscious QFD to rotary switch: a case study

General public and government agencies seriously view the environmental issues. Environmental issues have become an imperative concern for most companies in relation to modern product development. These activities stimulate the environmentally friendlier production technologies with a focus on minimization of environmental impact. Special procedures have to be formulated during the product development process to comply with recent green directives. In order to improve the focus on eco-designed products with regard to customer needs and cost considerations, this study presents the application of fuzzy eco-quality function deployment (QFD) to aid product design team in considering environmental concerns. This fuzzy multi-objective model considers the overall customer satisfaction and encourages enterprises to produce environmentally friendlier products. The case study describing the evolution of eco-friendly model of rotary switch has been presented. An optimal balance between environmental acceptability and overall customer satisfaction has been obtained as an outcome of the conduct of the study.
