Question 1

What is the primary objective of linear programming in industrial engineering?

Accepted Answer

To maximize or minimize a linear objective function subject to linear constraints

Answer

Linear programming optimizes (maximizes or minimizes) a linear objective function subject to a set of linear equality or inequality constraints.

Question 2

In the simplex method for linear programming, the optimal solution always occurs at which location in the feasible region?

Accepted Answer

At a corner point (extreme point/vertex) of the feasible region

Answer

The fundamental theorem of linear programming guarantees that if an optimal solution exists, it occurs at a corner (vertex) of the convex feasible polyhedron.

Question 3

The Economic Order Quantity (EOQ) model determines the optimal order quantity by minimizing the total of which two costs?

Accepted Answer

Ordering (setup) cost and inventory holding (carrying) cost

Answer

EOQ balances ordering/setup costs (which decrease with larger orders) against inventory holding costs (which increase with larger orders) to find the cost-minimizing quantity.

Question 4

In PERT/CPM network analysis, the critical path is defined as:

Accepted Answer

The longest path through the network, which determines the minimum project duration

Answer

The critical path is the longest sequence of dependent activities from start to finish; any delay on this path directly delays the entire project.

Question 5

Time study, a classical work measurement technique, is primarily used to:

Accepted Answer

Establish standard times for performing defined work tasks

Answer

Time study involves observing and timing a qualified worker performing a task at a normal pace, then applying rating factors and allowances to establish a standard time.
