Question: In this assignment we will build a simple simulation model for a car maintenance service. Assume that, we have two types of cars: sedan cars and SUV cars. Interarrival time for sedan cars is exponential 15 minutes. Interarrival time for SUV cars is exponential 20 minutes. After arriving, two types of cars enter a single pre-maintanance. In the pre-maintenance, there exists single worker with a single FIFO queue. Also, the processing time in pre-maintenance depends on car type. If a sedan car arrives, the processing time will be TRIA(3,5,7)minutes. If a SUV car arrives, then the processing time will be UNIF(6,10)minutes. After the pre-maintanance,30%of the cars go to full package care with single worker and a single FIFO queue. The processing time for full package care point is exponential distribution with mean 20 minutes. The rest(70%)goes to normal care for cars which also have single worker with a single FIFO queue. The processing time for this one is triangular distribution with minimum 8 , most likely 10 and maximum 15 minutes. Right after these processes, there exists single final check point which has single worker with single FIFO queue. If a sedan car arrives to final check point, the processing time will be triangular distribution with minimum 5 , most likely 7 and maximum 9 minutes. If a SUV car arrives to final check point, then the processing time will be Weibull distribution with parameter5.5and7.8minutes. In addition, after the final check point, cars are divided into 3 groups:8%of the cars will go back to pre-maintanance process,12%of the cars will leave the service with negligible problems and the rest (80\%) will leave the service with no problem. Run the simulation model for 2000 minutes in a 24 hours per day period and collect these statistics: - Collect statistics for queue length, queue time and utilization of the resources - How many sedan cars and SUV cars leaves this healthcare system? - Calculate the cycle time for negligible problematic cars and no problematic cars. - Which process or processes would you consider as bottleneck(s) of this system, why? Support your answer by using the simulation report. You are required to: i) Explain the steps you followed when you build the model (you can use screen shots). ii) Comment on each of the statistics given above. Submit your simulation report, your comments and your answers in a single document via itslearning. iii) Submit your doe file and .out file of your model and to do so please use itslearning

Reminder: Notice that, this task requires individual work. Your work should be yours and unique. No cheating or you will get a 0 (zero). In addition, no late submission or you will get 0 (zero) Grading policy for project: Arena implementation \& report:60%, comments \& inferences:30%, document organization:10%(clear, neat and well organized report) Hint 1: Do not use "-" symbol in your models when giving names to your modules and resources. If you type any symbol, you will get an error. Hint 2: You will use Create, Process, Dispose, Decide, Assign and Record modules while building your model.
