A manufacturer is designing a product layout for a new product production. It plans to use a production line for 8 hours per day in orderto meet forecasted demand of 180 units per day. The product requires 7 tasks in total. These tasks are namely. A. B,C.D.E.F. and Grespectively. Task A does not have any predecessor to start. To start Task B, it requires Task A to be completed. Starting tasks C needs,the task B to be completed. Also, starting task D needed task B to be completed. Task E can only start upon completion of Task C.Whereas starting task F needs the completion of both the tasks Dand E. Finally, starting task Gneeded, task F to be completed. Theprocessing times for tasks, A, B. C, D, E, F, and G are 2.4, 2.2,0.9, 1.0, 1.2, 1.8, are 15 minutes respectively. Applying the mast remainingtasks rule for balancing the assembly line, with ties broken according to longest task time first. What will be the idle time for theSECOND Workstation?a. 0.27b. None is the correct answerOc 1.67O d. 0.57O e. 0.47

Cycle time = Production time/Demand = (8 * 60)/180 = 2.67 minutes Minimum number of workstations:…

The product time per day is 8 hours and the production schedule requires 300 pizzas per day by the assembly time. 1. Draw the precedence diagram of the operation. 2. Determine the cycle time of the line. 3. Calculate the minimum number of workstations for this operation. 4. Construct the line layout of the operations following by rules below: 5. Longest task time rule. 6. Number of following rules. 7. Compute the resulting efficiency and balance of delay percentages. 8. If a worker is paid RM35 per day, compute the cost of idleness per week (assuming a work 6-day week).

Regarding section D with assigning the workstations: How would Task F go first if it could not be completed with Task D? Usint LOT. regardless of the time each took, doesn't one still have to bare in mind the predecessors? I would assume Tasks A and B would be Workstation 1, considering that 45 plus 20 seconds is less than the cycle time and factoring in the fact that C only requires A to be completed, hence why the workstation should start at A followed by C.
