------------------------------------------------- Top of Form Process Analysis Practice Problem Porthos Bakery Exercise Porthos Bakery is a commercial bread baker located in Cambridge, MA. Porthos supplies bread to many Boston area restaurants. The owners have recently been asked to supply a major restaurant with five locations in the greater Boston area. Before committing to the new business, Porthos wants to evaluate its current capacity; specifically, how many pounds of bread it can produce each hour. Once capacity is known, Porthos owners can decide if they are able to take on the additional demand. You have been asked to help Porthos owners with their decision by analyzing their current production process. Current average daily demand is 1000 lbs of bread. The average order size is 50 lbs.

Mixing | 10lbs/10min x 3 machines = 30lbs/10min = 3lbs/1min3lbs/1min/3 = 1lbs/.33min | 3lbs/min x 60min = 180lbs/hr180hr x 8hrs = 1440lbs/day | 2. Proofing | 10lbs/30min x 7 Machines = 70lbs/30min = 7lbs/3min = 2.33 lbs/1min =1lbs/.429min | 2.33lbs/1min x 60min = 140lbs/hr140lbs/hr x 8hrs = 1120lbs/day | 3. Baking | 40lbs/60min x 4 machines =
