Georgetown Pizza makes its favorite pan pizzas every day with three working shifts around the clock. The current completely cooked pizza-making process has a fixed cost of $24,000, and a variable cost of $2.75 per pizza. The owner is considering a different process that can make pizzas in two ways: completely cooked and selling at $13.98 per unit, or partially cooked with a selling price of $12.98 per unit. This alternate process has a fixed cost of $28,000, but a lower variable cost (because much less energy is used in baking) of $2.25 per pizza.
a. Determine the breakeven quantity between the current pizza-making process and the alternate process.
Bill builds benches in a small shop and he plans to operate five 8-hour days perweek. Each bench has two ends and a top. It takes 5 minutes to cut and sand eachend and 2 minutes to make each top. Assembly requires 8 minutes per bench, andpainting requires 5 minutes per bench. Bill has one employee who makes the topsand ends. Bill will do the final assembly and painting. He also plans 1 hour per dayfor setup and teardown for each department.a. How many benches should he plan to build per week?b. How many hours per week are required for each person?c. Suggest ways to increase the number of benches produced per week
The process below is a simple process for a bakery to make cookies. It consists of mixing the ingredients, letting the dough chill, shaping the cookies, and then baking them. The bakery needs to make 500 sheets of cookies per day. Cookies are baked fresh daily, and they must complete baking within 6 to 8 hours.
What changes would you make to have the capacity of each step within 0.1 sheets/min of the other steps?

In addition, the new line makes use of one machine per workstation, while the old line has parallel machines at the workstations. The processes, along with their machine rates, number of machines per station, and average times for a lone job to go through a station (i.e., not including queue time), are given for each line in the following table: Process Old Line New Line Rate per Machine (parts/hour) # Machines per Station Time (minute) Rate per Machine (parts/hour) # Machines per Station Time (minute) Punching 15 4 4.0 120 1 0.50 Braking 12 4 5.0 120 1 0.50 Assembly 20 2 3.0 125…arrow_forward
