Purple Swift manufactures birdhouses in lots of 10. Eachbirdhouse takes 45 minutes to paint. After 10 birdhouses arepainted, the company switches paint color which requires aone hour changeover. The company works 8 hours per shift,one shift per day, 220 days per year. Currently the companyhas one paint booth. What is Purple Swift’s paint capacitycushion if it builds 2,000 birdhouses per year?

An assembly line with 50 activities is to be balanced. The total amount of time to complete all 50 activities is 60 minutes. The longest activity takes 1.8 minutes and the shortest takes 0.6 minute. The line will operate for 540 minutes per day. What are the maximum and minimum cycle times? Round your answers to one decimal place. Maximum cycle time:    minutes Minimum cycle time:    minutes How much daily output will be achieved by each of those cycle times? Round your answers to the nearest whole number. Daily output achieved by maximum cycle time:   units/day Daily output achieved by minimum cycle time:   units/day

An assembly line is to be designed to operate 13 hours per day and supply a steady demand of 325 units per day. Here are the tasks and their performance times:   TASK PRECEDINGTASKS PERFORMANCE TIME (SECONDS) TASK PRECEDINGTASKS PERFORMANCETIME (SECONDS) a — 48 g d 43 b — 58 h e 38 c — 73 i f 23 d a 63 j g 33 e b 88 k h, i 53 f c 23 l j, k 67     A) What is the efficiency of your line balance? B) Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 13 hours per day in regular time. (Round your answers to the nearest whole number.)

A work center assigns tasks to 7 work stations. The total of all the task times is 24. If the cycle time used is 3.5, what is the efficiency of this configuration? (Round your answer to1 decimal places.) Efficiency %

A production process at Brianna Bryant Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel). a) is the bottleneck. 1.8 units/hr Sawing minutes per unit (round your response to two decimal places). 5 units/hr Sanding Drilling 5 units/hr b) The bottleneck time is c) The throughput time of the overall system is minutes (round your response to two decimal places). d) If the firm operates 11 hours per day, 20 days per month, the monthly capacity of the manufacturing process is Welding 2.5 units/hr Assembly 0.8 units/hr Assembly 0.8 units/hr Assembly 0.8 units/hr units (enter your response as a whole number).

ABC made upgrades to the production process and achieved a 25% increase in production with less raw material. At the same time, however, an additional employee had to be hired. Under the old process, 5 employees could produce 60 pieces per hour at a cost of $16/piece of raw material. With the new process, the cost of the raw material has been reduced to $10 per piece. The direct labor cost is $12/hour per person and overhead is calculated at 1.6 times the direct labor cost. The finished products are sold at a price of $31 each. Calculate the increase in productivity that has occurred by improving the production process.

Bagot Copy Shop has a volume of 125,000 black-and-whitecopies per month. Two salespeople have made presentationsto Gordon Bagot for machines of equal quality and reliability.The Print Shop 5 has a cost of $2,000 per month and a variablecost of $.03. The other machine (a Speed Copy 100 ) will costonly $1,500 per month, but the toner is more expensive, drivingthe cost per copy up to $.035. If cost and volume are the onlyconsiderations, which machine should Bagot purchase?
