Problem $5\mathrm{.}7\mathrm{.}4$Consider an office where people come to get their drivers$$ licenses. The process involves three steps for arriving customers $$ recep$$on$/$applica$$on; a vision exam; and a wri$$en exam. Assume that customer arrivals are Poisson with a rate of $6$ per hour $($i$.$e$.,$ interarrival $$mes are exponen$$ally distributed with a mean of $10$ minutes$).$ The processing $$me distribu$$ons for the three processes are given in Table $5\mathrm{.}7\mathrm{.}4.$ The office has one person responsible for recep$$on$/$applica$$on and one person responsible for administering the vision exams. The wri$$en exam is computer$-$based and there are three computer sta$$ons where customers can take the exam. Develop a Simio model of this system. Assume that the office opens at $9$:$00$ a$.$m$.$ and closes at $5$:$00$ p$.$m$.$ The performance metrics of interest include: $1.$the $$me that customers spend in the system,$2.$u$$liza$$ons of the office employees and the computer sta$$ons$,3.$the average and maximum numbers of customers in the recep$$on$/$applica$$on queue, the vision exam queue, and the wri$$en exam queue. How many replica$$ons should be run in order to be confident about your results? Jus$$fy your answer in wri$$ng$.$ Table $5\mathrm{.}7\mathrm{.}4$: Processing $$me parametersProcess Processing $$me distribu$$onRecep$$on$/$applica$$onTriangular $(5,8,11)$ Vision exam Triangular $(2,4,6)$ Wri$$en examTriangular $(10,15,20)$
