“…To calculate the probabilities for these defined fuzzy sets, X i ( P), X i ( Q), X i ( R)expressions are defined in ( 23)-(25). For computation of these expressions,expansion up to some specific degree term of exponential membership functions has been used.vary the results in [1,2,3,47]and the present model suggests the fast service than the other models i.e. patients' waiting time is lesser than the others' work (1)(2)(3)(4) .…”
