- Which of the following most directly expresses the motivation behind the expression "Do not block the bottleneck"? Multiple Choice O O O If the bottleneck has nothing to work on, the overall capacity of the process will be lower than it could be. If the bottleneck is prevented from working (e.g., it has nowhere to put its output), the overall capacity will be reduced. Blocking the bottleneck will increase the coefficient of variations of the arrival process, which decreases capacity. Blocking the bottleneck increases inventory turns, which increases the annual holding costs. It is not good to block the bottleneck because there are economies of scale in inventory management.arrow_forwardIn a job shop, effective capacity is only 88 percent of design capacity, and actual output is 69 percent of effective output. What design capacity would be needed to achieve an actual output of 11 jobs per week? What is its effective capacity?a. The Design Capacity needed to achieve the required actual job outputs =( ) (round to whole number)b. The Effective Capacity needed to achieve the required actual job outputs =( ) (round to whole number)arrow_forwardTeddy Fields is the Kitchen Manager at the Tanron Corporation International Headquarters. The facility he helps manage serves 3000 employees per day. Teddy very much needs an additional dishwasher, and is interviewing Wayne, an excellent candidate with 5 years experience who is now washing dishes at the Roadway restaurant. Teddy normally starts his dishwashers at $12.00 per hour. Wayne states that he makes $13.00 per hour, a rate that is higher than all but one of Teddy’s current dishwashers. Wayne states that he would not leave his current job to take a “pay-cut”. Should Teddy offer to hire Wayne at a rate higher than most of his current employees? Why or why not?arrow_forward
- Jefferson Company’s demand for its only product exceeds its manufacturing capacity. The company provided the following information for the machine whose limited capacity is prohibiting the company from producing and selling additional units. Actual run time this week 6,106 minutes Machine time available per week 8,600 minutes Actual run rate this week 4.32 units per minute Ideal run rate 6.00 units per minute Defect-free output this week 11,315 units Total output this week (including defects) 15,500 units 1. Compute the utilization rate.2. Compute the efficiency rate. 3. Compute the quality rate. 4. Compute the overall equipment effectiveness (OEE).arrow_forward11. Leo manages a receiving station for rice. Farmers deliver their loads of rice from 7 am to 7 pm. Leo can process them at a rate of 4.5 tons an hour, and on a heavy day, a total of 96 tons can be expected. The station has room to hold only 15 tons of rice in inventory prior to processing. Once this space is filled, the farmers’ trucks must wait to dump their contents. What is the throughput (flow) rate after 7 pm (in tons/hr)?arrow_forwardJB Bunt's fleet repair facility has the capacity to repair 800 trucks per month. However, due to scheduled maintenance of their equipment, management feels that they can repair no more than 600 trucks per month. Last month, two of the employees were absent several days each, and only 400 trucks were repaired. What is the utilization of the repair shop?arrow_forward
- A toy firm produces drums sequentially on three machines- A, B, and C- with cycle times of three, four, and six minutes, respectively. a) Determine the optimum efficiency and output rates for adding one, two... six more machines b) Assume now that two identical lines are operating, each with machines A, B, and C. If new machines can be shared between the lines, how should one, two, and then three new machines be added? What are the resulting efficiencies and outputs of the two lines? Is it always best to equally share extra machines between the two lines?arrow_forwardPlease don't provide handwritten solution ...arrow_forwardOrder 1 2 3 4 5 Time Since Order Arrived (hours ago) 3 1 0 6 5 You answered Sequence Order The due dates reflect the need for the order to be at its next operation. Develop separate schedules by using the FCFS and EDD rules. Compare the schedules on the basis of average flow time and average past due hours. Using the FCFS (first come, first served) decision rule for sequencing the orders, the order is Sequence Order Estimated Machine Time (hours) 15 9 7 10 3 1 5 Rule EDO FCFS 4 4 Using the EDD (earliest due date) decision rule for sequencing the orders, the order is (to resolve a tie, use order in which the orders were received) ¹2 1 4 2 3 Due Date (hours from now) 5 5 3 18 20 21 12 The average flow time and average past due hours for each option (enter your responses are real numbers rounded to two decimal place Average Flow Time Average Past Due Hoursarrow_forward
- L. Winston Martin (an allergist) has an excellent system for handling his regular patients who come in just for allergy injections. Patients arrive for an injection and fill out a name slip, which is then placed in an open slot that passes into another room staffed by one or two nurses. The specific injections for a patient are prepared, and the patient is called through a speaker system into the room to receive the injection. At certain times during the day, patient load drops and only one nurse is needed to administer the injections. Use Exhibit 712. Let's focus on the simpler case of the two-namely, when there is one nurse. Also, assume that patients arrive in a Poisson fashion and the service rate of the nurse is exponentially distributed. During this slower period, patients arrive with an interarrival time of approximately 3 minutes. It takes the nurse an average of 2.50 minutes to prepare the patients' serum and administer the injection. a. What is the average number of patients…arrow_forwardWhy is the Hayes and Wheelwright product-process matrix NOT used to analyze service delivery systems? a. The relationship between volume and process is not found in many service businesses. b. Services tend to have lower variety, so the variety element of Hayes & Wheelwright is not applicable. c. Services cannot add capacity. d. When services change processes to increase volume, they can still handle a wide variety of customer requests.arrow_forwardA 3 year-old a computer-controlled fabric cutting machine, which had a $25,000 purchasing price, has a current market (trade-in) value of $10,000 and expected O&M costs of $4,000, increasing by 1,000 per year. The machine is required to have an immediate repair that costs $2,000. The estimated market values are expected to decline by 20% annually (going forward). The machine can be used for another 7 years at most. The new machine has a $40,000 purchasing price. The new machine's O&M cost is estimated to be $4,000 for the first year, decreasing at an annual rate of $100 thereafter. The firm's MARR is 10%. Assume a unique minimum AEC(10%) for both machines (both the current and replacement machine). Using the information above, determine the economic service life along with the optimum annual equivalent cost of the defender (This is an infinite Horizon decision problem). a) n=4 and AEC=Between $8,400 and $8,800 b) n=4 and AEC=Between $8,000 and $8,400 c) n=5 and AEC=Between $8,400 and…arrow_forward
