Consider a Mobile Device Assembly and Quality Assurance System. The system consists of several key

steps: component assembly, software installation, functional testing, and final packaging. The assembly

line processes two types of products: Smartphone A and Tablet B$.$

System Description:

Smartphone A and Tablet B arrive at the assembly line according to separate exponential distributions.

Smartphone A arrives every $6$ minutes, while Tablet B arrives in batches of $3$ every $40$ minutes.

A production worker is responsible for the assembly of Smartphone A with a triangular distribution with

a minimum of $2$ minutes, a mode of $5$ minutes, and a maximum of $9$ minutes. For Tablet B$,$ the assembly

takes a triangular distribution with a minimum of $6$ minutes, a mode of $10$ minutes, and a maximum of $15$

minutes.

After assembly, both products go through software installation and this is done by a technician.

Smartphone A has TRIA$(2,3,4)$ minutes installation time, while Tablet B installation time is Weibull

distributed with a scale parameter of $7$ minutes and a shape parameter of $4.$ You must use single Process

module for modeling the technician.

Functional testing follows the software installation, which is a shared process for both products. The

testing time for Smartphone A is exponentially distributed with a mean of $8$ minutes, and for Tablet B$,$ it's

exponentially distributed with a mean of $12$ minutes. This process is done by a tester.

$10\%$ of all products require rework after testing which takes an exponentially distributed time with a

mean of $20$ minutes and $90\%$ will move for packaging. After rework, $15\%$ of the products is considered

as scrapped product and the remaining are assumed to pass the test and move to packaging.

Final packaging for Smartphone A takes a TRIA$(1,2,3)$ minutes, and for Tablet B$,$ it takes

TRIA$(1\mathrm{.}5,2\mathrm{.}5,3\mathrm{.}5)$ minutes.

Modeling Requirements:

Develop an ARENA model to simulate the described system for five days of $8-$hours shifts $(40$

replications$).$

Report the following results from the simulation:

$1.$ Utilization of all resources.

$2.3.$ Average total time in the system for Smartphone A and Tablet B$.$

Average waiting time and average number in queue for all Queues.

Deliverables:

One member of the group should submit $***.$Zip$$ file contains the following on blackboard:

$1-2-$ An MS$-$WORD file report contains the answers for the above questions, detailing the simulation

model, assumptions, and results $($with detailed cover page$).$

The ARENA model file $($i$.$e$.*****.$doe$).$
