Currently the manufacturer has seven machines that operate on a two-shift (eight hours each) basis. Twenty days per year are available for scheduled maintenance of equipment with no process output. Assume there are 250 workdays in a year. Each manufactured good takes 25 minutes to produce. a. What is the effective capacity of the factory? Round your answer down to the nearest whole number. units/year b. Given the five-year forecast, how much extra capacity is needed each year? Use a minus sign to enter an answer, if there is excess capacity. Rounc your answers to the nearest whole number. C. Does the firm need to buy more machines? If so, how many? When? If your answer is zero, enter "0". Round your answers up to the nearest whole number. The basic pizza-making process consists of (1) preparing the pizza, (2) baking it, and (3) cutting and boxing (or transferring to a platter for dine-in service). It takes five minutes to prepare a pizza, eight minutes to bake it, and one minute to cut and box or transfer. If the restaurant has only one preparer at each stage, what is the theoretical capacity of each stage of the pizza-making process in pizzas per hour? Assume that each operation is performed in series and independently, and that the oven can bake only one pizza at a time. Round your answers down to the nearest whole number. If the restaurant has two preparers at each stage, what is the theoretical capacity of each stage of the pizza-making process in pizzas per hour? Assume that each operation is performed in series and independently. Use answers for the first question in your calculations. Round your answers down to the nearest whole number
