a. Do gach of the following:
(1) Draw the precedence diagram. (4 pts.)
(2) Assign tasks to stations in order gf most following tasks. Tiebreaker: greatest
Rositional weight.

line assuming a 420-minute working dav.
b. Answer these questions:
(1) What is the shortest cxcle time that will pemit use of only two workstations?
Is this cycle time feasible? Identify the tasks vou would assign to each station.
(2) Determine thE REICentage of idle time that would result if two stations were
used.
(3) What is the daily Qutputunder this arrangement?
(4) Determine the Qutput rate that would be associated with the maximum cycle
time.
