Using a graphical solution procedure to solve a maximization problem requires that we:

a) move the iso-profit line up until it no longer intersects with any constraint equation.

b) move the iso-profit line down until it no longer intersects with any constraint equation.

c) apply the method of simultaneous equations to solve for the intersections of constraints.

d) find the value of the objective function at the origin.

When applying LP to diet problems, the objective function is usually designed to:

a) maximize profits from blends of nutrients.

b) maximize ingredient blends.

c) minimize production losses.

d) maximize the number of products to be produced.

e) minimize the costs of nutrient blends.

Automobiles arrive at the drive-through window at the downtown Baton Rouge, Louisiana, post office at the rate of 4 every 10 minutes. The average service time is 2 minutes. The Poisson distribution is appropriate for the arrival rate and service times are negative exponentially distributed.

What is the average number of cars in the system?

An assembly line is to be designed for a product whose completion requires 21 minutes of work. The factory works 400 minutes per day. Can a production line with five workstations make 100 units per day?

a) Yes, with exactly 100 minutes to spare.

b) No, but four workstations would be sufficient.

c) No, it will fall short even with a perfectly balanced line.

d) Yes, but the line's efficiency is very low.

e) Cannot be determined from the information given.

Which of the following is not a valid LP constraint formulation?

a) $3 X+4 Y \leq 12$

b) $2 X \times 2 Y \leq 12$

c) $3 Y+2 Z=18$

d) $100 \geq X+Y$

e) $2.5 X+1.5 Z=30.6$

a. What information is included on each line of the petty cash register? b. Why is the petty cash register not considered a journal?

Which system extends MRP II to tie in customers and suppliers?

a) MRP III

b) JIT

c) IRP

d) ERP

e) Enhanced MRP II

A process-oriented layout:

a) groups workers to provide for movement of information.

b) addresses the layout requirements of large, bulky projects such as ships and buildings.

c) seeks the best machine utilization in continuous production.

d) allocates shelf space based on customer behavior.

e) deals with low-volume, high-variety production.

Product development systems include:

a) bills of material.

b) routing charts.

c) functional specifications.

d) product-by-values analysis.

e) configuration management.

A fixed-position layout:

a) groups workers to provide for movement of information.

b) addresses the layout requirements of large, bulky projects such as ships and buildings.

c) seeks the best machine utilization in continuous production.

d) allocates shelf space based on customer behavior.

e) deals with low-volume, high-variety production.

What are the three factors that complicate a fixed-position layout?

The bullwhip effect can be aggravated by:

a) local optimization.

b) sales incentives.

c) quantity discounts.

d) promotions.

e) all of the above.

What is the difference between a gross requirements plan and a net requirements plan?

Automobiles arrive at the drive-through window at the downtown Baton Rouge, Louisiana, post office at the rate of 4 every 10 minutes. The average service time is 2 minutes. The Poisson distribution is appropriate for the arrival rate and service times are negative exponentially distributed.
