An assembly line is designed to operate 7 1/2 hours per day and supply a steady demand of 300 units per day. The tasks and their performance times are below: Performance Preceding Tasks none none none Task 70 45 10 30 20 60 50 15 25 20 25 H,I a. draw the precedence diagram for the process above. b. caclulate the cycle time for this operation c. determine the theoretical minimum number of work stations d. Assign tasks to the work stations using the longest operating time heuristic. e. determine the efficiency of the line before and after balancing.
