The batch size is cut in half on a resource that has a setup time. What is the likelyimpact on the resource’s capacity?a. Decrease by more than 50 percentb. Decrease by 50 percentc. Decrease by less than 50 percentd. No impact
A 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. What would be themixed-model sequence if some of each were made each day?
1. 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…

- Which of the following regarding the impact of batch size is WRONG? a. A large batch size increases the total time in a cycle. b. A large batch size introduces more output variation to the process. c. A large batch size generates a high level of inventory. d. A large batch size improves the capacity. But the marginal capacity improvement has a decreasing trend. e. None of the above.arrow_forward. 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_forwardRefers to the range of the number of items produced by the operation over a givenperiod of time. choose the correct answer(1) Volume of output.(2) Variation of output.(3) Variety of output.(4) Transformation process.(5) Transmission processarrow_forward
- Increasing the batch size on a resource with setups always increases the capacity of theprocess. True or false?a. True b. Falsearrow_forwardP1 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_forward
- A convenience store uses the fixed-period inventory control system (FPS) to manage its inventory of distilled water bottles. This system relies on the following information. (a)Using EOQ (rounded up), what is the time interval between reviews T in operating days? Note that after having the rounded-up EOQ, you should not round up values at intermediate steps; and, you should round T up only after the last calculation. (For example: enter 10 for 10 days.) (b) What is the current inventory position (IP) in bottles? (For example: enter 70 for 70 bottles) (c)Without safety stock, what is the replenishment level without safety stock M(AD) in bottles? Note that the question does not ask for M(ST). (For example: enter 70 for 70 bottles) (d)If today is the review day and without safety stock, what is the order quantity in bottles given M(AD)? (For example: enter 70 for 70 bottles)arrow_forwardIn order to produce 1000 units of X in a week units X is scheduled weekly for Operation B (due to 5% scrap ratio) units X is scheduled weekly for Operation A (due to 2% scrap ratio) Based on your answer in part a, find the number of machines required to produce 1000 units of X per week. The total time required to perform Operation B = minutes per week The total time required to perform Operation A = minutes per week H= Available Time in a week = minutes /week Thus FA = . FB = .
