Application of early sustainability assessment to support the design of industrial systems

Nowadays industrial products require numerous aspects to be integrated and optimized contemporarily and interactively: mechanics, electronics, system control, management of material and information flows, interfaces, human-product interaction, as well as impacts on environment, costs and human factors. As a consequence, the design of industrial products has to combine new advanced functionalities and high performances by limiting production cost as well as environmental and social impacts. It means that the entire industrial system has to be designed looking towards sustainability. While attention to cost and environmental performance is not new, the analysis of social-related aspects is basically unexplored for industrial products. Achieving social sustainability includes forecasting human behaviours, actions and reactions, analysing how human beings interact with objects, tools, devices and interfaces, and assessing their physical and mental workload. The present research proposes an analytical approach to support the design of industrial products by providing an early sustainability assessment of the three aspects of sustainability (environment, cost and people). It adopts a feature-based approach and a set of key performance indicators (KPIs) to assess the sustainability of the manufacturing and assembly processes and to support an easy and preventive analysis during product design. The paper presents the application of such method to industrial cases.
