5.            The stepping-stone method is used to:

 

 

 

a.            obtain an initial (1st) solution.

 

b.            balance source supply and destination

 

demand.

 

c.             evaluate occupied cells (routes) for possible

 

cost reductions.

 

d.            evaluate empty cells (routes) for possible

 

cost reductions.

 

 

 

 

 

6.            Which of the following statements is true?

 

 

 

a.            evaluation paths selected must be as short

 

as possible.

 

b.            evaluation paths may contain diagonal move-

 

ments.

 

c.             occupied cells may not be bypassed if turning

 

movements are desired.

 

d.            all occupied cells of each solution must be eval-

 

uated.

 

 

 

 

 

7.            The intent of the load-distance model is:

 

 

 

a.            to minimize the number of workers.

 

b.            to minimize idle time per cycle.

 

c.             to minimize materials and / or information

 

movement costs within a process layout.

 

d.            none of the above.

 

 

 

 

 

8.            Which of the statements about line-balancing is true?

 

 

 

a.            if a precedence relationship exists between tasks

 

A and B, they cannot be assigned to the same

 

work station.

 

b.            if a line’s balance delay factor is maximized, its

 

efficiency is maximized.

 

c.             the theoretical minimum number of work stations

 

can never be achieved, hence the name “theoretical”.

 

d.            if the cycle time is reduced, productivity will increase.
