Doog's Donuts produces five varieties of pastries, which are sold to a national grocery chain: muffins, donuts, cookies, cream puffs, and fritters. Assuming that Doog's operates a single shift for 1,800 hours per year, calculate the required capacity. The processing time per unit, setup time per lot, the annual demand, and lot size are given in the table. Assume that the times given are for a work cell of four workers each, so required capacity should be in terms of the number of work cells needed.
