Simulation 2-1

1. Tentukan Start Service Time, Waiting Time, Completion Time, Time in System untuk masing-masing customer.

2. Rata-rata Waiting Time = 2.443. Maximum Waiting Time = 5.64. ATM Utilization = Busy Time / Last Completion Time = 26.90 / 30.2 = 0.8907 = 89.07% 5. Simulasi untuk 200 customer menggunakan data :a. Inter Arrival Times terdistribusi normal dengan mean 2.06 dan standard deviation 0.506b. Service Times terdistribusi normal dengan mean 2.506 dan standard deviation 0.706

Rumus Excel = NORMINV(RAND(),mean,stdev)

Simulation 2-2

1. Tentukan Start Service Time, Waiting Time, Completion Time, Time System.

2. Rata-rata Waiting Time = 0.763. Maximum Waiting Time = 1.94. ATM Utilization

Busy Time 1 = Total Service Time pada Mesin ATM 1 = 2.9 + 2.6 + 3.4 + 2.9 + 4.1 = 15.9Busy Time 2 = Total Service Time pada Mesin ATM 2 = 3.2 + 2.1 + 2.8 + 3.4 + 4.0 = 15.5

ATM 1 Utilization = Busy Time 1 / Completion Time ATM 1 = 15.9 / 19.50 = 0.815384615 = 81.5%ATM 2 Utilization = Busy Time 2 / Completion Time ATM 2 = 15.5 / 20.60 = 0.752427184 =75.2% 6
