  3. Antrian • λ • μ • ρ = λ/μ • Lq = λ2/ μ(μ- λ) = ρ2/(1- ρ) • Ls = λ/(μ- λ) = ρ/(1- ρ) • Wq = Lq /λ = λ/ μ(μ- λ) • Ws = Ls /λ = 1/(μ- λ)

  5. Teori • Definisi Kinerja • Sifat indeks kinerja: • Calculated • Measured • Estimated • Istilah indeks kinerja: • Turnaround time • Response time • Throughput • Capacity • Reliability • Reaction time • dll.

  6. Teori • Kriteria pengukuran: • Objektif • Reliable • Valid • Normalisasi • Ekonomis • Berguna • Precision vs confidence

  7. Teori • Definisi model sistem • Klasifikasi model sistem: • Struktural • Fungsional • Analitikkinerja • Tingkatan representasi model sistem komputer: • Level 1 - Fisikal • Level 2 - Virtual • Level 3 - Fungsional

  8. Teori • Sifat antrian • Notasi Kendall: • A/S/m/B/K/SD
