The Wilcox Student Health Center has just implemented a new computer system and service process to $$improve efficiency.$$

The process flowchart and analysis framework is also provided. As pharmacy manager, you are concerned about waiting time and its potential impact on college students who $$get no respect.$$

All prescriptions $($Rxs$)$ go through the process shown in Exhibit $11\mathrm{.}29.$ Assume that students arrive to drop off Rxs at a steady rate of two Rxs per minute, with an average of one Rx per student.

The average number of students in process $($assume waiting and being serviced$)$ at each station is drop off$$five students, pick up$$three students and pay cashier$$six students.

The fill Rx station typically has $40$ Rxs in process and waiting on average.

Because of this perceived long wait, $95$ percent of the students decide to come back later for pick up$.$ They come back an average of three hours later.

If the students choose to stay, each name is called as soon as the Rx is filled, and the student then enters the pick$-$up line. Assume that the system is operating at a steady state.

People and information flow with the assumption of one Rx per student. Demand $($arrival$)$ or throughput rate $5$ two Rxs$/$minute
