Abstract

Highlights: AI tool is developed for deciding the suitable life cycle design parameters. An Artificial Neural Network approach is utilized for developing the tool. Tool identifies the trade-off between environmental load and cost effectiveness. Time efficiency of proposed AI tool is significantly higher than that of GaBi 9.2. Abstract: The consideration of sustainability aspects in initial stages of product development is understood as an effective approach to plan a sustainable product life cycle. It can be achieved by integrating the sustainability considerations into decision making of companies in early design phases. This study aims to develop an Artificial Intelligence (AI) tool that can assist the designers in their decision making to choose environmentally benign design parameters of products. The proposed tool is based on an Artificial Neural Network (ANN) model which takes the life cycle design parameters (viz. size of product, density of material, manufacturing process, transport mode and recyclability) as inputs and provides the corresponding outputs in terms of 'carbon footprint' and 'life cycle cost' of a product. These outputs assist the designers to realize the trade-off between the environmental load and cost effectiveness of a design alternative. Thus, it enables the decision making of companies to select a more sustainable design. A Graphical User Interface (GUI) is developed for the AI tool so that the designers can efficiently use this tool. The results predicted by the proposed tool are compared with the results obtained through the life cycle assessment carried out by using GaBi 9.2. The comparison shows that the results predicted by the tool have a reasonable accuracy of more than 90% which is significant, especially in the design stages of environmentally conscious product development. Also, the time efficiency of the tool to compute the environmental impact was compared with that of GaBi 9.2 by using a T-test. Results showed that the time efficiency of the proposed AI tool is significantly higher than that of GaBi 9.2.
