“…Since production resources (machines, robots, operators and so on) are usually scarce, they must be used efficiently to increase system throughput (Li, Ambani, & Ni, 2009). In maximising throughput, it is essential to identify bottleneck machines in a production system so that maintenance (and other production improvement activities) can be focused on these (Gopalakrishnan, Skoogh, & Christoph, 2013;Wedel, Von Hacht, Hieber, Metternich, & Abele, 2015;Guner, Chinnam, & Murat, 2016). A system-level decision support tool is therefore needed, to analyse these bottleneck machines (Jin, Weiss, Siegel, & Lee, 2016).…”
