     many subsystems are involved in the reliability modeling of combined heat and power (chp) systems, but in most studies these subsystems have not been classified and in many cases have been considered separately. furthermore, calculating the reliability from the generation point to the consumer has not yet been studied. herein, we classify combined heat and power subsystems and model their reliability, availability and mean-time-to-failure indices based on interactions between subsystems from the generation site to consumer delivery. the proposed chp reliability and availability model is based on the state space and the continuous markov method with electricity-generation, fuel-distribution and heat-generation subsystems. the effects of fuel- and water-distribution networks at the chp site and the hot-water-distribution network on the consumer-utility reliability of chp systems were fully assessed in an applicable case study. additionally, we present a sensitivity analysis for island, standby and parallel operational modes of chp systems. the results from the case study prove that improving the gas-distribution network, the network delivering hot water to the consumers and the water-delivery network to the chp, in addition to optimizing the failure and repair rates of chp systems, have considerable effects on the reliability improvement of the complete integrated system and have major roles in technical and economic feasibility studies of chp systems.
