Problem: An office that dispensos automotive license plates has divided its customers into the ones to level the office workload. Customers arrive and enter one of three lines based on their residence location Model this arrival activity as three independent arrival streams using an exponential interarrival distribution with mean 10 minutes for each stream. Each customer type is assigned a single separate clerk to process the application forms and accept payment with a separate queue for each. The service time is UNIE (8, 10) minutes for all customer types. After completion of this step, all customers are sent to a single, second clerk who check the forms and issues the plates (this clerk serves all three customer types, who merge into a single first come first served queue for this clerk). The service time for this activity is UNIF (2.65, 3.33) minutes for all customer types. Develop a model of this system and run it for a single replication of 5,000 minutes; observe the average and maximum time in systam for all customers types.com (scenario 1). A consultant has recommended (scenario 2) that the office not differentiate between customers at the first stage and use a single line with three clers who can process any customer type. Develop a model of this system, run it for a single replication of 5,000 minutes, and compare the results with those from the first system Performance Measure Value Average time in system for all customer types combined of scenario Maximum time system for all customer types combined of scenario 1 Average time in system for all customer types combined of scenario 2 Maximum time in system for all customer types combined of scenario 2
