The Action Toy Company has decided to manufacture a new train set, the production of which is broken into six steps. The demand for the train is 4800 units per 40-hour workweek:

This exercise only contains parts b, c, d, e, and f.

b) Given the demand, the cycle time for the production of the new train set = seconds (round your response to one decimal place).

c) The theoretical minimum number of

work stations =

Assignment of tasks to workstations can be done by using an assignment heuristic like longest task time and following the guidelines outlined below:

1. Task time across all jobs assigned to a workstation should

beCycle

Time.

2. Task's precedence requirements should be satisfied.

3. (Cycle

TimeWorkstations

Operational Time) should be minimized.

4. New workstation, assign longest time activity available first whose precedence requirements are satisfied.

5. A task can only be assigned to one workstation.

(round your response up to the next whole number).

d) Using the longest operation time rule, the assignment of tasks to workstations should be: (Hint: Number workstations sequentially in terms of precedence relationships and combine any applicable tasks.)

Were you able to assign all the tasks to the theoretical minimum number of workstations?

e) The total idle time per cycle for the process = ___________seconds (enter your response as a whole number)

.f) The efficiency of the assembly line with 5 workstations =___________ (enter your response as a percentage rounded to one decimal place).

If one used 6 workstations instead of 5, the efficiency of the assembly line would be = ___________ (enter your response as a percentage rounded to one decimal place).
