Part B:

System Description:

Consider a flow line layout manufacturing shop, where manufactured parts pass through three consecutive machines namely: Drill, Tapping machine and Painting machine. Processing times of the parts on the mentioned machines are shown in the following table $($Time in minutes$)$:

$\backslash$table$[[$Entity$,$Inter arrival time$],[$Part I,Expo $(20)],[$Part II$,$Expo $(27)],[$Part III,Expo $(28)]]$

$\backslash$table$[[$Process$,$Resource,$\backslash$table$[[$Part I processing$],[$time$]],\backslash$table$[[$Part II processing$],[$time$]],\backslash$table$[[$Part III processing$],[$time$]]],[$Drilling Process,Drill,Triangular $(2,4,5),$Triangular $(2,3,4),$Triangular $(1,2,4)],[$Tapping Process,Tapping machine,Normal $(3,1),$Normal $(2,1),$Normal $(3,2)],[$Painting Process,Painting machine,Uniform $(3,5),$Uniform $(1,2),$Uniform $(3,4)]]$

In drilling process, Part I has the highest priority in the queue then Part II and after that Part III

In Tapping process, the queue ranking based on Last come first served.

In Painting Process, Part III has the highest priority in the queue then Part II and after that Part I.

Also, it takes $2$ minutes to transfer the parts between the three different machines and $4$ minutes transfer time between the entering and the drilling machine and the painting machine location and the exit point of the system.

Modeling Requirements:

Develop an ARENA model to simulate the described system for $7$ days of $8-$hours shifts $(20$ replications$).$ Use max arrival for each Part to be $50.$

Report the following results from the simulation:

What is the average total time of the parts in the system?

what is the average time each part spends in processing $"$VA Time", waiting in queue and the transfer time?

Add stations and routes animation

Show the number of entities in each queue using Variable

Plot the Number of entities in process vs time for each process $($Use one plot $3$ time series and adjust the Y and X axis scales to appropriate values$)$

Note: Use Three process modules only
