A fuzzy hedging point policy for sustainable manufacturing system

This paper addresses a sustainable manufacturing system, i.e. a manufacturing system on which we try to minimize all economical costs while minimizing environmental impacts and improving workforce welfare. Indeed, on one hand, this system emits pollutants and greenhouse gases during its manufacturing process. On the other hand, the social dimension i.e. the human workforce and its working conditions are also discussed and considered because of the direct and indirect costs associated. A hedging point policy is then applied and adapted to this manufacturing system by using fuzzy logic to ensure sustainability. So, a fuzzy hedging point is defined to take into account pollutant emissions and human factors in order to minimize global costs.
