5a. (15 points) How many ICU beds do we need in each stroke hospital to ensure that all hospitals have a utilization less than or equal to 92% ? How does the total number of ICU beds under the proposed bed allocation policy compare with the total number of beds under the policy that allocates 30 ICU beds to each stroke hospital? 5b. (5 points) What would be the average waiting time (in minutes) in each hospital under the bed allocation policy proposed in Question 5a? 6. (15 points) What is the minimum number of beds you should allocate to each stroke hospital to ensure that the average waiting time of each stroke hospital is less than or equal to 9 minutes? Table 2: Travel time (in minutes) from the centroid of each region to the centroid of each stroke hospitals in Toronto. Emma obtained GPS travel times from Google map as the average of the best and worst travel tin 2016. Formulas required to solve the case 1. Utilization =c 2. Average number of patients in a pooled queue: Iq(1)2(c+1)2C2+Cs2 3. Average waiting time in the queue: Tq=Iq (Little's law)
