dc.description.abstractThe collected district heating (DH) rehabilitation experiences in economies in transition (ET) in Europe, financed by international financing institutions (IFI), were analyzed. Linear regression analysis was used when assuming the benefits gained by investments in new pipelines, pumps, heat exchanger stations (substations), heat metering, temperature controllers, thermostatic radiators valves and heat cost allocators. Based on the outcome, a computerized dynamic model over time span was created by means of linear (LP) and non-linear (NLP) programming under the GAMS1 programming environment that, based on the analyzed experience, can optimize the DH rehabilitation strategy for a given number of years in other DH systems being candidates for comprehensive rehabilitation. The model was successfully tested in a Russian type system.en_ZA
