Abstract
In Industry 4.0, electric vehicles for logistics are widely used, such as shuttles for transporting people and Autonomous Guided Vehicles for industrial equipment. Environmental impact analyses and eco-design guidelines are essential tools in the design phase, where choices have a decisive effect on the entire product life cycle. This work proposes a method and tool aiming to make industrial electric vehicle designers aware of their choices. The proposed tool allows the preventive analysis of the different life cycle phases to highlight the consumption of materials and energy required to optimize the use and the End of Life strategy. Furthermore, it is intended to support the designers who are not provided with much product lifecycle information to obtain an overall picture of how environmental impacts are spread throughout the lifecycle; this will help provide feedback on their choices a pave the way for a more sustainable use phase in the manufacturing plant. It is based on developing a simplified and modular structure where the main product parameters are included for each life cycle phase. The tool is validated in a case study regarding the customization of an Autonomous Mobile Robot, equipped also a robotic arm; the two are connected by a customized structure. The results, which focus both on environmental and economic perspectives, contribute to filling the existing gap in the environmental evaluation of the analyzed product segment; moreover, they highlight how the material and manufacturing phase may be outstanding over the use or End of Life. This is mainly due to the short distances covered during the useful lifetime, which only cover industrial plant areas.
