Problem 1: Patient volumes for a radiology clinic are observed to have the following time-series data: Monday = 25, Tuesday = 28, Wednesday = 32, Thursday = 26, and Friday = 30. Using a 5-day moving average, and ignoring week-end volumes, what is the projection for the following Monday? If you used a 3-day moving average, using Wednesday through Friday values, how would the forecast change?
Problem 2: Assume that a hospital has a single-phase, multiple-channel waiting line. There are 2 employees, 10 customers currently in line, and new patients arrive at the rate of approximately 40 patients per hour. Calculate the average wait time.
Problem 3: Ten observations of cycle time were made, and the average observed cycle time was 17 minutes. Using an allowance factor of 20%, calculate the standard time for this process.
Please include details and the steps.
