This work presents a fuzzy optimisation model for HEN retrofit design incorporating parametric uncertainties. The basic model is based on a stage-wise superstructure with non-isothermal mixing. Fuzzy set theory is used with max-min aggregation to provide a robust, more conservative design with maximum overall degree of satisfaction of fuzzy constraints. An illustrative example is presented to demonstrate the application of the proposed approach. Results obtained for the deterministic and fuzzy cases are discussed and compared with the literature.
