About 80% of customer who receive a promotion coupon will visit the store, but only 20% of those in the store will make a purchase. What is the overall process yield of the promotion?
16%
(Of the 100% of customers who received a coupon, 80% visited the store, and 20% of those made a purchase. Overall process yield = 1 × 0.80 × 0.20 = 0.16.)
Customers at an e-retailer site abandon their shopping carts without completing their purchase. This is an example of _____________.
Attrition loss
Which of the following statements is TRUE regarding implied utilization?
A resource with an implied utilization of 1.7 means that demand exceeds capacity by 70%.
(Implied utilization = Total demand at the resource/Capacity at the resource. Therefore, if implied utilization is 1.7, that means demand exceeds capacity by 1.7 - 1 = 0.7 or 70%.)
A workload table has __________ as columns and __________ as rows.
flow unit types, resource types
C&A makes two types of products using four machines from 9 a.m. to 5 p.m. each day. Product A visits machines 1, 2, and 4. Product B only visits machines 1 and 3. The capacity is 0.4 unit per minute at machine 1, 0.12 unit per minute at machine 2, 0.2 unit per minute at machine 3, and 0.3 unit per minute at machine 4. The demand per day is 40 units for Product A and 160 units for Product B. What is the implied utilization for machine 1?
1.04
(Total demand for machine 1 = 40 + 160 = 200 units per day. Capacity for machine 1 = 0.4 unit per minute or 0.4 × 8 × 60 units per day. Implied utilization for machine 1 = 200/(0.4 × 8 × 60) = 1.04.)
A workload table captures the __________ that each flow unit type requires for each resource.
amount of work
A ________ is a combination of different types of flows through a process.
product mix
C&A makes two types of products using four machines from 9 a.m. to 5 p.m. each day. Product A visits machines 1, 2, and 4. Product B only visits machines 1 and 3. The capacity is 0.4 unit per minute at machine 1, 0.12 unit per minute at machine 2, 0.2 unit per minute at machine 3, and 0.3 unit per minute at machine 4. The demand per day is 40 units for Product A and 160 units for Product B. Which resource is the bottleneck?
Machine 3
(Total demand for machine 1 = 40 + 160 = 200 units per day. Total demand for machine 2 = 40 units per day. Total demand for machine 3 = 160 units per day. Total demand for machine 4 = 40 units per day. Implied utilization for machine 1 = 200/(0.4 × 8 × 60) = 1.04. Implied utilization for machine 2 = 40/(0.12 × 8 × 60) = 0.69. Implied utilization for machine 3 = 160/(0.2 × 8 × 60) = 1.67. Implied utilization for machine 4 = 40/(0.3 × 8 × 60) = 0.28. The bottleneck is the resource with the highest implied utilization, which is machine 3.)
Which of the following process flow diagrams DOES NOT represent a process with rework?
-> Box -> Box ->
Students who failed a course last semester are retaking it this semester. This is an example of __________.
rework
A manager is concerned that there isn't enough time spent on production and too much time spent on setups. The manager decides to double all production batch sizes. This change has no impact on demand. What impact will this likely have on the average inventory in the process?Average inventory will increase because larger batches require more time to be completed.C&A Printing takes 10 seconds to print a page in color, but after 500 pages, the printer must be cooled down for 15 minutes. No pages can be printed while the printer is cooling down. C&A's demand rate is 3 pages per minute. What is the smallest batch size to ensure the process is demand-constrained?90 (Capacity of the printer = 3 pages per minute. Use the formula Batch size = (Target capacity × Total setup time)/[1 - (Target capacity × Processing time)] = (3 × 15)/[1 - (3 × 10/60)] = 90)A machine makes three different components used in a gyroscope. Call these components A, B, and C. The following repeating schedule is used to make components: make 100 units of A, make 50 units of B, and then make 200 units of C. How many components are made in the production cycle?350Which of the following graphs correctly portrays the relationship between batch size (x-axis) and capacity of a resource with setups (y-axis)?----------------------------------- - - - - - -A cutting machine takes 10 minutes to cut a piece of component for a product. After cutting 200 pieces, the machine takes 5 minutes to be recalibrated. What is the setup time of the cutting process?5 minutesIn a supply-constrained process, the ideal batch size is one that __________ inventory in the system and results in a process capacity that matches the __________.minimizes, bottleneck capacityC&A Furniture uses a four-step process to make its famous wood table: Process Processing Time Milling-table top 10 min. Milling-table stand 5 min. Assembly 15 min. Finishing 20 min. The milling machine requires a setup time of 30 minutes to make table tops and a changeover time of 30 minutes to make table stands. C&A works an 8-hour day. What is the capacity of the milling machine (in tables per day) if the batch size is 10?22.86 (Capacity = Batch size/(Total setup time + (Processing time × Batch size). Total production and setup time for ten tables = 30 + (10 × 10) + 30 + (5 × 10) = 210 minutes. Batch size is 10. Capacity = 10/210 or 0.048 tables per minute. For capacity per day, 10/210 × 8 hrs × 60 minutes = 22.86 tables per day.)C&A Printing takes 10 seconds to print a page in color, but after 500 pages, the printer must be cooled down for 15 minutes. No pages can be printed while the printer is cooling down. C&A's demand rate is 10 pages per minute. What is the utilization of the printer?85% (Capacity of the printer = 500/[15 + (10/60 × 500)] = 5.08 pages per minute. Flow rate = Min(10, 5.08) = 5.08. Utilization = Flow rate × Processing time = 5.08 × 10/60 = 85%.)C&A produces three kinds of bread: wheat, white, and multigrain. The data on these products are given below: Wheat White Multigrain Demand (lbs per hour) 50 20 10 Changeover time (min) 60 30 45 Production rate (lbs per hour) 200 200 200 How many pounds of wheat bread should C&A produce with each batch in order to minimize inventory while satisfying demand?187.5 (Batch size = (Capacity × Setup)/[1 - (Capacity × Processing time)]. Capacity = 50 + 20 + 10 = 80 lbs per hour. Setup = (60 + 30 + 45)/60 = 2.25 hours. Processing time = 1/200 hour. Batch size = (80 × 2.25)/[1 - (80 × 1/200)] = 300. Batch size for wheat = (300 × 50)/80 = 187.5.)C&A Furniture uses a four-step process to make its famous wood table: Process Processing Time (minutes) Milling—table top 10 Milling—table stand 5 Assembly 15 Finishing 20 The milling machine requires a setup time of 30 minutes to make table tops and a changeover time of 30 minutes to make table stands. What is the total setup time (in minutes) in the above process?60 (Milling setup = 30 minutes; Milling changeover = 30 minutes. Therefore, the total setup time = 60 minutes.)In the Toyota Production System, jidoka refers to __________.Mechanisms used in production to stop the process and alert workers when a quality problem is detectedA lean operation strives to achieve a reduction of __________ and __________ simultaneously.waste in capacity, flow timeThe benefits of a smooth single-unit flow include all of the following EXCEPT ______.reduced worker turnoverWhich of the following is NOT an example of wasted capacity?Flow timeWhich of the following is an example of wasted flow time?A long waiting time at a checkoutWhich of the following statements is FALSE regarding overall equipment effectiveness (OEE)?OEE can exceed a value of one.The overall equipment effectiveness framework identifies what percentage of a resource's time is __________ and what percentage is __________.value-added time, wasted timeWhat term refers to combining machines in production with the intelligence of workers?AutonomationWhich of the following can be used to uncover a waste of flow time?Inventory Level__________ means to produce in the amounts needed, when needed, and where needed using a single unit flow.Just-in-timeThe Pareto principle states that_________ of the problems can be traced back to ____________ of the root causes.80%, 20%____________ illustrate how the ___________ variable is being influenced by the input and ____________ variables.Fishbone diagram, outcome, environmentalWhich of the following is an example of foolproofing?A saw that will not start if the blade is not inserted properly in its housingWhich of the following is an example of early warning?A fire alarm that goes off when a fire is detected in a buildingC&A operates a dry cleaning service.
