- The Southeastern Sports Company produces golf clubs on an assembly line in its plant in Marietta, Georgia. The final assembly of the woods requires the eight operations given in the following table. (given) a. Draw a network to represent the assembly operation.b. What is the minimum cycle time that can be considered? Determine the balance that results from the ranked positional weight technique for this cycle time.c. By experimentation, determine the minimum cycle time that can be achieved with a three-station balance.arrow_forwardFrancis Johnson's plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 15 units per hour, and there is room for only five workstations. The tasks and the order in which they must be performed are shown in th following table.
