A separate analysis of each of these fast subsets is done and each fast recurrent subset is replaced by a single slow state while the fast transient subset is replaced by a probabilistic switch. D) probabilistic, probabilistic 53) Which of the following is not an assumption or a characteristic of a Markov Process? By Victor Powell. Once a company has forecast the demand for labour, it needs an indication of the firm's labour supply. Markov techniques can be applied to model these systems by breaking them down into a set of operating (or failed) states with an associated set of transitions among these states. Pres entations in the literature of the theory of NHMS have flourished in recent years Vas- siliou and Georgiou [7], Vassiliou .
