The hospital has 89 beds are these sufficient? Flow rate = {28 + 28 + 28 + 28 + 28 + 0 + 0}[patients] / 7 [days] =(or 140 patients a week/7 days) = 20 [patients/ day] Flow time = 3.5 [days] (average of 3 and 4) WIP = 20 [patients/ day] * 3.5 [days] = 70 patients Do we have a problem? Since 70 people need 70 beds, 89 APPEARS to be ok. WIP = Flow rate * Flow time [Q] = [Q / T ] * [T ] Mgmt 361 Chapter 2 - Process Analysis 6
