The purpose of the calculations below is to show how many beds are needed with the arrival of 27 patients per day, five days a week. Patients arrive Sunday to Thursday.

1. Arrival rate of 27 per day; 5 days a week (Sunday to Thursday); arrive in afternoons.

2. 13 leave in 3 days (3-night stays; for example, arrive on Sunday afternoon and leave on Wednesday morning) and the other 14 in 4 days. Departing patients leave in the morning)

Note: They have 89 beds. In addition, they have 14 hostel type beds. All 89 regular beds plus 6 hostel type beds fully utilized on two days a week (W and TH).

Question:

1. What is the average flow rate?

2. What is the average flow time for a patient?

3. What is the average number of patients in the system?

4. Does Little's Law hold for this example? If not, Explain why. (Little's Law: WIP = Flow Time / Cycle Time = Flow Time * Rate Time)
