In the developed model the process and energy integration tech- niques are principally investigated. In the present work, a case study is discussed to demonstrate the proposed model. The results illustrate that by selecting the adequate resources, centralized and decen- tralized conversion technologies and distribution networks, the environmental impacts can be reduced down to 50e65% and the total annual costs down to 22e27%. In addition, 75% efficiency is obtained due to the integration of co-generation technologies, endogenous resources and the waste heat recovery.District energy systemsMixed-integer linear programming (MILP)Evolutionary algorithmMulti-objective optimizationCase studyurban_systemsIND_DESSCCER_FURIEStext::journal::journal article::research article
