Interarrival Time Distribution: Exponential of mean $=1\mathrm{.}1$ min.

Service Distribution: Server $1$: Exponential of mean $=0\mathrm{.}8$ min.

Server $2$: Exponential of mean $=1\mathrm{.}0$ min.

Number of Locations $=3$

Number of Entities $=1$

Compare and simulate for $12$ hours, $0$ warmup time, $1$ replication

Scenario $1$ The situation as shown above versus

Scenario $2$ Adding a queue before the bottleneck $[$Save the

original model in a new file, go to Build Locations, ad add a new

location as queue, then go to Build Processing and re$-$route the

relevant processes. Save and run$]$

Scenario $3$ Adding a new parallel server at the bottleneck $[$Save

the original model in the new file, go to Build Locations and at the

bottleneck location, go to Units: change value from $1$ to $2,$ then save

and run.$]$

Compare and contrast the three scenarios with respect to the

utilization of the $3$ elements: server, queue and entity. Show he

scenario with the best utilization. Analyze and defend all the

conclusions given here
