The table below defines the precedence relationships and element times for a new assembled product. (a) If the ideal cycle time is calculated as 1.2 min with no repositioning time, what is the theoretical minimum number of workstations required to minimize the balance delay under the assumption that there will be one worker per station? (5 p) (c) Using smallest candidate rule, assign work elements to stations. (20p) (d) Compute the balance efficiency for your solution. (15 p) Work T. (min) Immediate Work T. (min) Immediate element predecessors element predecessors 0.37 0.15 4 0.41 5 0.2 6,7 8 0.62 9, 10, 11 4 2 3 4 0.4 0.5 0.2 0.6 0.25 0.3 8 9 10 11 12 2 0.3 6
