As the Cottrell Bicycle Co. of St. Louis completes plans for its new assembly line, it identifies 25different tasks in the production process. VP of Operations Jonathan Cottrell now faces the job ofbalancing the line. He lists precedences and provides time estimates for each step based on work-sampling techniques. His goal is to produce 1,000 bicycles per standard 40-hour workweek.TaskTime (sec)ImmediateTaskTime (sec)ImmediatePredecessorsPredecessorsK360E3109F3K424K3D653F4K927K3D772F9, E2, E3J166K3D878E3, D6J222K3 -D937D6J33C178F7G479K4, K9B372D7, D8, D9, C1G529К9, 1B5108C1F33212B718B3F492J2A152B5F721J3A272B5F9126G4A3114B7, A1, A2E218G5, F3a) Balance this operation using shortest operation time rule and compute the efficiency of the line.b) Discuss how this balance could be improved.

A local toy maker uses a manufacturing line running eight hours a day that produces a toy which needs 7 tasks in total. The regular requirements are 100 toys. Task times are 2.73,2.01,2.13,2.0.2.11,2.71 and A,B,C,D,E,F and G, respectively, 2.95 minutes. However, there are precedent laws because of the essence of the substance that must be followed. This type of task has no predecessors; task B needs the completion of task A. To begin task C and task D, each task requires the completion of task B. Mission must be done until task E is defined. Goal F has to be done with Task D and Task Finally, task G will only start until task Fis has been completed. Since we extend the remaining job rule to balance the production line with the linkage broken in the longest working period, check circle is the task allocated to the THIRD station
