Contribution of cost-benefit analysis to optimization of eco-design plants

Purpose – This study aims to interest the eco-design of the systems. This interest is justified by the need to reducing the environmental impacts in phase of the design plant. Design/methodology/approach – It consists of a proposal for a combined methodology of the industrial systems eco-design. This methodology is based on the simultaneous use of a cost-benefit analysis (CBA) method and dependability tools. Findings – In the developed approach, we use the dependability tools for modeling of the functional behavior of the industrial systems and the CBA method for optimization of the industrial system constraints which are in fact environmental constraints. Practical implications – Methodology suggested constitutes an invaluable help to ensure a better integration of the environment in production. Originality/value – Methodology suggested is tallied by the CBA method, which makes it possible to manage the conflict relation between production and environmental protection.
