Fine’s Furniture is known for its fine cedar chests. The tasks necessary to assemble the cedar chests, the length of time needed to perform each task, and the operations that must be complete prior to subsequent operations are given below. With a production quota of 300 units in a 35 hour week, the desired cycle time is closest to ______.
If Fine’s can only afford 3 workers to man the line (i.e., one worker per work station), how many chests can be produced in a 35-hour week?
| Element | Time (min) | Predecessors |
| A | 2 | NONE |
| B | 3 | A |
| C | 5 | B |
| D | 5 | NONE |
| E | 4 | D |
| F | 1 | NONE |
| G | 2 | F |
| H | 4 | C, E, G |
Solution
desired cycle time DT= time available / output = (35 hrs * 60 mins)/ 300 = 7 mins
-----------------------------------------------------
no of workers = sum of task /cycle time
or sum of task =3*7=21
chest produced=( 21*35)/3 =233(approx)
