Assignment 2: Due Sept 18th, 2018 (beginning of class)<\/p>\n

MGT 303<\/p>\n

For your convenience, an excel spreadsheet is posted together with this<\/p>\n

homework on blackboard. You can find the data you need and do calculations in<\/p>\n

excel to answer Questions 4 and 5.<\/p>\n

    \n
  1. Metters Cabinets, Inc., needs to choose a production method for its new office<\/li>\n<\/ol>\n

    shelf. It could implement either a product focus process or repetitive process. To<\/p>\n

    help accomplish this, the firm has gathered the following cost data:<\/p>\n

    Process Type Annual\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Fixed<\/p>\n

    Cost<\/p>\n

    Variable\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Cost\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 (per\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 unit)<\/p>\n

    Labor Material<\/p>\n

    Product\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Focus\u00a0\u00a0\u00a0 $50,000\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 $10 $10<\/p>\n

    Repetitive\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Focus $25,000\u00a0\u00a0\u00a0 $18\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 $12<\/p>\n

    Compare these two process types using a crossover chart. Find the production<\/p>\n

    volume that Metters Cabinets is indifferent between the two process strategies.<\/p>\n

      \n
    1. Wally\u2019s Widget Warehouse takes orders from 7 AM to 7 PM. The manager wants<\/li>\n<\/ol>\n

      to analyze the process and has provided the process flow diagram shown below<\/p>\n

      (with capacity rates at each step). There are three steps required to ship a<\/p>\n

      customer order. The first step is to take the order from a customer (one customer<\/p>\n

      places one order). The second step is to pick the order for the customer, and<\/p>\n

      then they have to pack the order ready for shipping. There are currently only<\/p>\n

      three workers taking care of these three steps; one for each.<\/p>\n

      Wally wants to figure out the following:<\/p>\n

        \n
      1. How many customer orders at most can this process deal with per day<\/li>\n<\/ol>\n

        assuming a 12-hour working time?<\/p>\n

          \n
        1. What is the process time of the order picker?<\/li>\n
        2. If orders arrive every 1.5 minutes, what is the process utilization? (Hint:<\/li>\n<\/ol>\n

          how many orders have arrived in one hour as the input?)<\/p>\n

            \n
          1. Wally is not satisfied with the number you give in (a); he wants the<\/li>\n<\/ol>\n

            process capacity to become larger. There is a worker recently hired. Who<\/p>\n

            do you want the new worker to help? Order taker, picker, or packer?<\/p>\n

            Why?<\/p>\n

              \n
            1. Following question (d). Assume that the new worker can help double the<\/li>\n<\/ol>\n

              capacity rate at the step he is sent to. Would hiring this new worker<\/p>\n

              double the number you give in question (a)? Why?<\/p>\n

                \n
              1. Consider the example we did in class:<\/li>\n<\/ol>\n

                Suppose that each output unit generates $10. An extra resource (1, 2, or 3) can<\/p>\n

                be leased for $14 per hour. If you have a budget of $28 (that is, you can lease at<\/p>\n

                most two resources), should you go for it? If yes, which one\/ones should you<\/p>\n

                lease? And how much is your net hourly gain if you are about to lease?<\/p>\n

                  \n
                1. Auto pistons at the South Florida plant are produced in a forging process, and<\/li>\n<\/ol>\n

                  the diameter is a critical factor that must be controlled. From sample sizes of 10<\/p>\n

                  pistons produced each day, the mean and the range of this diameter have been<\/p>\n

                  as shown in the spreadsheet.<\/p>\n

                  Hint: you may need Table S6.1 in the textbook.<\/p>\n

                    \n
                  1. If the population (process) standard deviation is 0.5, what are the Upper<\/li>\n<\/ol>\n

                    Control Limit and Lower Control Limit for sample means using 3-sigma?<\/p>\n

                      \n
                    1. Without the knowledge of the population standard deviation, find the<\/li>\n<\/ol>\n

                      Upper Control Limit and Lower Control Limit of sample means using 3-<\/p>\n

                      sigma.<\/p>\n

                        \n
                      1. Find the Upper Control Limit and Lower Control Limit for the range using<\/li>\n<\/ol>\n

                        3-sigma<\/p>\n

                          \n
                        1. Five data entry operators work at the data processing department of the Georgia<\/li>\n<\/ol>\n

                          Bank. Each day for 30 days, the number of defective records in a sample of 250<\/p>\n

                          records typed by these operators has been noted, as shown in the spreadsheet.<\/p>\n

                            \n
                          1. Establish the 99.73% upper and lower control limits for a p-chart.<\/li>\n
                          2. When we apply the control limits, what would we conclude if we saw a<\/li>\n<\/ol>\n

                            day\u2019s sample (250 records) has 21 defective records? How about only 1<\/p>\n

                            defective record?<\/p>\n

                            **Note: Show all your works**<\/p>\n
