============================ Ch. 6 =============================== 7. a. Take Order = 100 per hour * 12 hours = 1200 Pick Order = 80 per hour * 24 hours = 1920 Pack Order = 60 per hour * 24 hours = 1440 Maximum output is determined by order taking (1200) since the pick and pack operations can work up to 24 hours to clear out their order backlog. b. If we take the maximum of 1200 orders then: Pick Order = 1200 orders/80 per hour = 15 hours Pack Order = 1200 orders/60 per hour = 20 hours c. Orders can be taken at a rate of 100/hours and can be picked at the rate of 80/hour so they build at the rate of 20/hour. Orders are taken for 12 hours. Maximum orders waiting for picking = 20/hour * 12 hours = 240 d. Orders can be picked at a rate of 80/hours and can be packed at the rate of 60/hour so they build at the rate of 20/hour. Orders are picked for 15 hours. Maximum orders waiting for packing= 20/hour * 15 hours = 300 e. (b. revisited) If we take the maximum of 1200 orders then: Pick Order = 1200 orders/80 per hour = 15 hours Pack Order = 1200 orders/120 per hour = 10 hours However, Packing has to wait for the orders to be picked so it would be 15 hours (c. revisited) This answer does not change.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
