Please show your work, and explain it when necessary (do not simply state the answer). Problem 1 Please study the adjoining process flow diagram for the production of croissants, in batches of 50. The operations in each of the lines (Upper Line, Lower Line, and Combination Line) are sequential; that is they have to be performed one after the other. The Upper Line and the Lower Line work in parallel, if there is sufficient labor, and feed the Combination Line (consisting of the operations Fill and fold, Bake, and Pack). (1) Suppose Tim carries out the operations in the Upper Line, John carries out the operations in the Lower Line, and Beth carries out the operations in the Combination Line. Calculate the capacity of the process in batches per hour. (2) Suppose John is absent sick one day, and Tim carries out the operations on the Lower Line as well as the Upper Line. Beth carries out the operations in the Combination Line. Calculate the capacity of the process in batches per hour on this day.
