Activity $1$: For the given scenario perform a simulation in GPSS

Let us consider a scenario representing a machine tool in a manufacturing shop which is turning out parts at the rate of every $5$ minutes. The parts are then examined by the inspector who takes $4+-3$ minutes for each part and rejects about $10\%$ of the parts. We can represent each parts by one transaction, and the time unit selected for the problem will be $1$ minute.

perform the following for above scenario :

A$)$ Write a GPSS code for Single inspector $($single server$)$ and analyse the output for $1080$ parts and find Total simulation time duration, waiting time, utilization of the server.

B$)$ Write a GPSS code for three inspectors $($multi server$)$ and analyse the utilization of inspectors, waiting time

C$)$ What changes you will get if the time required to inspect the parts is $6+-2?$

What changes you will get if we increase one more inspector?

D$)$ Write a GPSS program that will tabulate the distribution of the parts inspection process according to time,
