$[$Questions $8-13,$ Queuing Theory$]$ Good BloodGood Blood develops and markets new technological products to be used in health care.The development of a new product operates as follows.The technology is first patented. Once the patent is approved and received, the technology waits for an available development center. Once a center becomes available, the technology undergoes development in that center. Good Blood has $5$ independent development centers.On average, Good Blood receives a new patent every $9$ months with a standard deviation of $12$ months. The average development process lasts $36$ months $($with a standard deviation of$24$ months$).$Once the technology is developed, it is then launched in the market.A$)$ How many servers are there, i$.$e$.,$ what is the value of m$?$B$)$ What is the average inter$-$arrival time in months?C$)$ What is the coefficient of variation of the inter$-$arrival time?D$)$ What is the coefficient of variation of service $($or processing$)$ time?E$)$ What is the utilization of Good Blood's development centers?F$)$ On average, how long $($in months$)$ does it take for the technology to start the development process $($at a development center$)$ after receiving the patent?
