BSIE Bachelor of Science in Industrial Engineering MCQ 3

Question 1

In linear programming, the simplex method moves from one basic feasible solution to another by performing which operation?

Accepted Answer

Pivot operation on the basis

Answer

The simplex method performs a pivot to swap one variable into the basis and one out, moving to an adjacent vertex of the feasible polytope.

Question 2

What does the 'takt time' represent in lean manufacturing?

Accepted Answer

The available production time divided by customer demand rate

Answer

Takt time = available production time ÷ customer demand, setting the heartbeat or pace of production needed to meet demand.

Question 3

In statistical process control, a control chart signals an out-of-control condition when a point falls beyond how many standard deviations from the centerline (under standard Western Electric rules)?

Accepted Answer

3

Answer

Standard control limits are set at ±3 sigma; a point beyond these limits signals a likely assignable cause.

Question 4

Which type of production layout arranges machines by the type of operation they perform, grouping all lathes together, all drills together, etc.?

Accepted Answer

Process layout

Answer

A process (functional) layout groups similar machines or functions together, suitable for low-volume, high-variety production.

Question 5

The EOQ (Economic Order Quantity) model minimizes the sum of which two cost components?

Accepted Answer

Ordering cost and holding cost

Answer

EOQ balances ordering (or setup) costs against inventory holding costs to find the quantity that minimizes total annual inventory cost.
