“…To help the user in handling exergy data, some heuristics and general rules have been established (Feng and Zhu, 1997) without specific alternatives. To overcome this problem, De Jong et al (1996) proposed combining AI techniques, and more precisely CBR systems, and exergy analysis to improve industrial processes. In the chemical engineering field, CBR systems have already been adopted for process designing (Ataei, 2011;Ataei and Yoo, 2010), separation process design (Ghorbani et al, 2012;Staine and Favrat, 1996), reactive distillation (Homsak and Glavic, 1996), mixing equipment selection (Anantharaman, 2011), process alternatives generation (Anantharaman et al, 2006) and more recently for cogeneration plant design (Aspelund et al, 2007;Gundersen et al, 2009).…”
