Lampiran 7 Lanjutan penurunan formulasi M/M/2 berdasar model Markov. pn didapatkan dengan menurunkan persamaan local balance yaitu:
λp0 = µp1 → p1 =
λ p0 µ
λp1 = 2µp2 → p2 =
λ p1 → 2µ
λp2 = 2µp3 → p3 =

Berdasar persamaan global balance, p0 =
2 p0 + p0 ρ = 2 − ρ p0 ρ + ρ = 2 − 2 p0
ρ ( p0 + 1) = 2 − 2 p0 ρ=
2 − 2 p0 2(1 − p0 ) = 1 + p0 1 + p0
Dengan menurunkan persamaan pn maka utilisasi CPU pada saat n > 0 dapat didapatkan dengan mengunakan persamaan: p −1 ρ= n pn + 1
