According to Little's law, which of the following can be used to estimate work-in-process inventory?

Throughput rate times Flow time

Assume a fixed cost for a process of $15,000. The variable cost to produce each unit of product is $10 and the selling price for the finished product is $25. Which of the following is the number of units that has to be produced and sold to break-even?

$25 - $10 = $15. $15,000/$15 = 1,000 units.

According to Little's Law, which of the following ratios is used to find throughput rate?

Inventory/Flow time

Which of the following basic types of process structures is one which equipment or work processes are arranged according to the progressive steps by which the product is made?

Assembly line

When balancing an assembly line, which of the following is not a way to reduce the longest task time below the required workstation cycle time?

Speed up the assembly line transfer mechanism

A difference between project and continuous flow categories of process flow structures is which two of the following?

The size and bulk of the product

Using the assembly-line balancing procedure, which of the following is the required cycle time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

Using equation 6.3, 480 minutes/50 units = 9.6 minutes per unit.

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

Using equation 6.5, [25/(6 x 5)] = 0.833.

Which of the following is a basic type of process structure?

Work center

Which of the following basic types of process structures is one which similar equipment or functions are grouped together?
