Line Balancing Calculation Problem: A factory is running an unbalanced line in an inefficient manner. Thirteen workers operate thirteen workstations in a straight run line. The process needs to be re-arranged to find a balance that minimizes the workstation cycle time using only five stations. Step 'a' must be done first, step 'm' done last, steps 'c' and 'd' are predecessors to step 'P, and all other steps can be done in any order. The required output is 1,200 units per day. Production happens in a continuous operation using three shifts of eight hours each. Please balance this line. Activity a b C d Time (Seconds) 30 50 40 50 1 20 10 10 20 10 30 20 m 50 10
