2 QUESTION 1 [5pt][Adapted from Problem Set 1 Q2] Consider a bagel store selling three types of bagels that are produced according to the process flow diagram outlined below. We assume the demand is 120 bagels a day, of which there are 40 grilled cheddar & veggie, 60 veggie only, and 20 cream cheese. Assume that the workday is 8 hours long and each activity is staffed with one worker. Moreover, we assume the following activity times: Activity Unit Load (per bagel) Cut 5 min Put Grilled Cheddar on Bagel 20 min Veggies on Bagel 8 min Cream cheese 20 min Wrap 3 min Activity times are independent of which bagel type is processed at a resource (for example, cutting a bagel takes the same time for a cream cheese bagel as for a veggie bagel).
