The manager has been asked to balance an assembly line to achieve a desired output of 275 units. Assume 440 minutes available per day. The tasks times and predecessors information is as follows: a) Draw precedence diagram and find the cycle time ( CT=1.6mnts) b) Determine theoretical number of work stations needed ( 2.6 rounded to 3 ). c) Assign tasks to stations and break ties using these rules: First, largest position weight; then most followers. If tie still persists, choose arbitrarily. d) Compute percentage of idle time and efficiency of the line
