“…Recently, there has been much interest and focus on the lifetime network and system reliability based on the concept of signatures; see, for example, Boland, Samaniego, and Vestrup (2003), Samaniego (2008, 2010), Rychlik (2007, 2010), Zhang (2010), Gertsbakh and Shpungin (2009, 2012, Levitin, Gertsbakh, and Shpungin (2011), Eryilmaz (2011, 2012 and Balakrishnan and Asadi (2012). The developments on the reliability and lifetime properties of coherent systems, however, are mainly based on the assumption that the system has n independent identically distributed (i.i.d.)…”
