ABSTRACT

In industrial practice, lots of systems exhibit more than two simple states up and down. Those systems are referred to as multi-state systems (MSSs) (Lisnianski et al., 2010). For example, the electric capacity generated from a power plant ranges from 0 kWh to 1000 kWh and the corresponding speed of a task processing system is recorded from 0/s to 100/s at a given time point. As a special representation, a component or a unit showing multiple output performances is regarded as the simplest example of an MSS, which is considered as a multi-state component (MSC).
