A finished goods inventory on average contains 10,000 units. Demand averages 1,500 units per week. Given that the process runs 50 weeks a year, what is the expected inventory turn for the inventory? Assume that each item held in inventory is valued at about the same amount.

- Increasing the batch size on a resource with setups always increases the capacity of theprocess. True or false?a. True b. Falsearrow_forward1. A donut store is open 8 hours a day and sells two types of donuts: blueberry cake donut and chocolate frosted donut. On average, the demand is 80 donuts per day for EACH type. The store has only one machine, which makes both types, and once it starts, it produces one donut every 2 minutes for either type. The production alternates between the two types, i.e., a batch of one type is followed by a batch of the other. The setup time is 20 minutes for either type. If the batch size is 10 donuts per batch, what is the capacity per day for each type of donut? If the batch size is 20 donuts per batch, what is the capacity per day for each type of donut? What is the minimal batch size in order to satisfy demand for both types? If the setup time is 8 minutes for either type, and the batch size is 20 donuts per batch, what is the capacity per day for each type of donut? (You can assume that at the end of the day, any unfinished production of the last batch can be resumed immediately…arrow_forwardAn order which is being processed on the shop floor but is not yet finished is called open order.

The primary purpose of the “Single-Minute Exchange of Die” philosophy is to:a. reduce the setup time for a resource.b. increase the flow rate of a process.c. decrease the utilization of a process.d. eliminate resources that have setup times.arrow_forwardA company produces a line of golf putters composed of three models. The demandfor model A is 500 per month, for B is 400, and for C is 300.

- P1 P4 P2 P3 P5 P5 P5 P6 ... P1 has a production rate of 15 units/hour, P2 = 30 units/hour, P3 = 10 units per hour, P4 = 4 units/hour, P5 = 1 unit(s) per hour for each P5 and P6 = 6 units per hour. Operation P4 occurs seperately from and simultaneously with operations P1-P3. Operation P5 has three parallel and identical lines; therefore, each part only needs to go through one of the three lines. Consider the following two independent improvements: Improvement 1: Change station P4 into two connected stations (P4-1 and P4-2, connected in series) that have process times of 4 min/unit and 6 min/unit respectively. Improvement 2: Add two additional P5 stations to give you 5 parallel and identical lines. Improvement 2 increases capacity because it improves the bottleneck. The new bottleneck is station P4 since the original bottleneck has a process time of The new yearly capacity would be units per year. a) Which of the two improvements will provide the largest increase in capacity? What is the…arrow_forwardA company wants to produce 10,00 units of an item over the next three months at a uniform rate. Because of an annual shutdown in the third month, the first month has 15 working days; the second, 18 working days; and the third, 10 working days. On the average, how much should the company produce each day to level production?arrow_forwarda. Customers are unhappy because they have to wait long periods to obtain a Furniture-A. The company comes to Doshisha Business School and hires you as a part-time consultant to improve the process capacity of producing items of Furniture-A. You cannot hire more workers because the current 10 workers are specialists with long-year experiences. It is difficult to find additional workers with those high skills. To match TJ with assembly process, you use the following "batch size formula" you learnt from Professor Yin's course to decide the appropriate batch size for C-I and C-II. But you are surprised that the answer is a negative number of -6.42857, gotten by (10/10 * 45)/(1-10/10 *8). Why does this formula not function?arrow_forward

The action figures are purchased from Tacky Toys, Inc., and arrive in boxes of 48. Full boxes are stored on high shelves out of reach of customers. A small inventory is maintained on child-level shelves. Depletion of the lower-shelf inventory signals the need to take down a box of action figures to replenish the inventory. A reorder card is then removed from the box and sent to Tacky Toys to authorize replenishment of a container of action figures. The average demand rate for a popular action figure, Agent 99, is 36 units per day. The total lead time (waiting plus processing) is 11 days. Jitsmart’s safety stocky policy variable, a, is 0.25.
