Fuzzy Application in Sustainability Assessment: A Case Study of Automotive Headlamp

Aspects of environment, economic and social are the three principal elements of sustainability. Within these elements, there are many sub-sustainability parameters need to be considered when sustainability evaluation is carried out which include pollution, cost, energy, health, acidification and others. The inclusion of these parameters and the uncertainty data increases the complexity in decision making process with respect to sustainable development as it not only evaluates the current situation but also the prediction and strategic decision for the future. Consequently, a simplified methods and tools are required in guiding the designers and decision makers to develop sustainable product. Hence, this paper present a fuzzy approach in evaluation of product’s sustainability. The fuzzy logic approach is integrated into the evaluation process as it has a capability to handle severe uncertainty and ability to evaluate qualitative and quantitative data simultaneously. A case study of automotive headlamp is presented to demonstrate the capability of fuzzy technique in sustainability evaluation.
