Cost-benefit analysis of ergonomics-sustainability projects with analytic hierarchy process

Today, sustainability gets a top priority on the agenda of the shortage of natural resources and regulations. Managers seek how to give minimum damage to the environment while keeping productivity. Ergonomics has an answer to trying to smooth the relationships between man and the elements of a system to optimize the whole system's performance and human satisfaction. Ergonomics and sustainability have common areas of interest in putting a man into the centre. Managers always seek ways to improve productivity but investing in employee wellness is often ignored. They are hesitant to fund projects like ergonomics and environmental until savings are proven. The proposed model in this study using Cost-Benefit Analysis (CBA) and Analytic Hierarchy Process (AHP) together may convince the decision makers to approve the ergonomics or environmental projects easily, which are seen as a pure expense at first.
