An assembly line with 20 activities is to be balanced. The total amount of time to complete all 20 activities is 50 minutes. The longest activity takes 2.4 minutes and the shortest takes 0.9 minute. The line will operate for 300 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 for a product whose completion requires 21 minutes of work. T he factory works 400 minutes per day. Can a production line with five workstations make !00 units per day? a) Yes, with exactly 100 minutes to spare.b) No, but four workstations would be sufficient.c) No, it will fall short even with a perfectly balanced line.d) Yes, but the line's efficiency is very low.e) Cannot be determined from the information given.

Daimler Chrysler’s plant that builds Viper and Prowler is the Motor City’s “hottest ticket.” The Viper-Prowler plant is not your typical Detroit assembly operation. Instead of mass production techniques using robots, it’s “craftsman-style” production for hand-building Vipers and Prowlers. With mass production, Daimler Chrysler can produce up to 75 cars per hour. With late shifts, Daimler Chrysler’s nearby Jefferson North Assembly Plant can crank out 1,114 Jeep Grand Cherokees in a 24-hour workday. By comparison, the Viper plant produces 13 Vipers a day and has a capacity for 20 Prowlers. A t 392,000 square feet, the Viper plant is a boutique compared to most massive auto plants, such as Saturn Corp.’s Spring Hill, Tenn., manufacturing complex, which is 5 million square feet. The Jefferson North plant has 2.4 million square feet. “ We’re not the biggest plant in the area, but we’ve got the best workforce and build the most exciting products—the Plymouth Prowler and Dodge Viper,” said…

Workstation cycle time is 115 seconds per unit and there are 4 workstations. What is the efficiency of the line balance and balance this line using the largest number of following tasks. Use the longest task time as a secondary criterion. Leave no cells blank - be certain to enter "0" wherever required. (Last Bartelby helper got the problem incorrect as shown in the picture).

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly line balancing procedure. The cycle time is 5 minutes, and the sum of all the tasks required ok the line is 25 minutes. What is the value of the resulting line’s efficiency?

The Sail-Sea is a boat manufacturer. The assembly location is available for production of 60 boats for  240 minutes per day.  Given the information in the table,  a) Draw the precedence diagram b) Fins the minimum number of workstations needed to produce the required daily demand. c) What is the efficiency of the assembly line d) What is the idle time per boat produced e) Assign the tasks to workstations using the most follower method f) What is the maximum theoretical capacity this line can achieve in 240 minutes

A shop works a 400-minute day. The manager of the shop wants an output of 200 units per day for the assembly line that has the elemental tasks shown in the table. Do the following: b.) Assign tasks according to the most following tasks rule. Break ties with the greatest positional weight rule. c.) Assign tasks according to the greatest positional weight rule. Break ties with the most following tasks rule. d.) Compute the efficiency level for each rule. Which one yields the better set of assignments in this instance?

The process design team at a manufacturer has broken an assembly process into eight basic steps, each with a required time and predecessor as shown in the table. They work an 8-hour day and want to produce at a rate of 360 units per day. What should their takt time be?

A production process at Kenneth Day Manufacturing is shown in Figure S7.9. The drilling operation occurs separately from, and simultaneously with, sawing and sanding, which are independent and sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).a) Which operation is the bottleneck?b) What is the bottleneck time?c) What is the throughput time of the overall system?d) If the firm operates 8 hours per day, 20 days per month, whatis the monthly capacity of the manufacturing process?
