Question: Use ARENA to develop a single server simulation model where customers arrive with Lambda = 12 Customer/hr to a service station of Mu = 15

Use ARENA to develop a single server simulation model where customers arrive with Lambda = 12 Customer/hr to a service station of Mu = 15 Customer/hr. Both arrival and service times are exponential.

The five performance measures are:

- Avg. waiting time (Wq)

- Avg. time in system (W)

- Avg. number of customers in queue (Lq)

- Avg. number of customers in system (L)

- Server utilization (U)

Procedure

: - Develop the ARENA model of the single-server system. (show the details of each element and insert the model picture here)

- Run the model for 40 hours (one week) of operation and obtain results report. Study and understand all the elements of the simulation report. Include the report of simulation results in the appendix.

- Use the simulation results to estimate the defined five performance measures. Report Averages of the five performance measures here:

Wq =

Lq =

W =

L =

U =

3 - Use the queuing formulas to calculate the defined five performance measures.

Wq =

Lq =

W =

L =

U =

- Compare formula results to simulation results and explain differences (Use a table to compare results).

- What can you do to obtain simulation results that are closer to formula values?

- Sketch resource utilization with run time, what do you conclude?
