An R-out-of-N repairable system, consisting of N independent components, is operating if at least R components are functioning. The system fails whenever the number of good components decreases from R to R-1. A failed component is sent to a repair facility. After a failed component has been repaired it is as good as new. Formulae for the availability of the system using Markov renewal and semi-regenerative processes are derived. We assume that either the repair times of the components are generally distributed and the components' lifetimes are phase-type distributed or vice versa. Some duality results between the two systems are obtained. Numerical examples are given for several distributions of lifetimes and of repair times.

Based on the renewal process theory we develop a decomposition method to analyze the reliability of the repair facility in ann-unit series system with vacations. Using this approach, we study the unavailability and the mean replacement number during(0,t]of the repair facility. The method proposed in this work is novel and concise, which can make us see clearly the structures of the facility indices of a series system with an unreliable repair facility, two convolution relations. Special cases and numerical examples are given to show the validity of our method.

While railways are considered as a sign of development for countries, the railway structures are part of the industrial heritage of cities and comprise some of the most important urban public places. In Turkey, the Eskişehir railway buildings, constructed between 1886 and 1894, are at the west of the main railroad between the Enveriye and Eskişehir stations. They are also public places having strong resonance in the collective memory. Because of the fast development in technology, they face the threat of losing their function. Conservation of former industrial structures requires, first and foremost, identifying and documenting the distinctive features that makes them cultural heritage sites. It is a shared responsibility between public institutions and sectors to identify and protect the distinguishing features of industrial heritage sites. With this awareness, at the Anadolu University Architecture Department, integrated student work focused on the Railroad Roundhouse—built in 1896—and Staff Housing Quarters—built in the early 20th century—which are part of this district and embody a series of urban problems, was carried out over four academic semesters. This study focuses on historic railway buildings in the Eskişehir railway district that is known for its urban problems. An exhibition combining these student works was opened at the Railcar Repair Facility on 16 November 2017. This exhibition showcased the student involvement in history of Eskişehir and increased public awareness of cultural heritage.
