C) 6
Using equation 6.4,
(7 + 4 + 7 + 8 + 9 + 4 + 3 + 6)/8 = 6. - Correct Answers -Using the assembly-line
balancing procedure, which of the following is the theoretical minimum number of
workstations if the task times for the eight tasks that make up the job are 7, 4, 7, 8, 9, 4,
3 and 6 minutes, and the cycle time is 8 minutes?
B) 0.833
Using equation 6.5, [25/(6 x 5)] = 0.833. - Correct Answers -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?
C) 0.750
Using equation 6.5, [60/(8 x 10)] = 0.750. - Correct Answers -You have just determined
the actual number of workstations that will be used on an assembly line to be 8 using
, the assembly-line balancing procedure. The cycle time of the line is 10 minutes and the
sum of all that tasks required on the line is 60 minutes. Which of the following is the
correct value for the resulting line's efficiency?
D) Speed up the assembly line transfer mechanism - Correct Answers -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?
D) Disposing of left-over machinery and outsourcing ungrouped processes - Correct
Answers -Which of the following is not a step in developing a manufacturing cell layout?
D) Fabrication - Correct Answers -Which of the following is not considered a major work
flow structure?
A) The size and bulk of the product - Correct Answers -A difference between project
and continuous flow categories of process flow structures is which two of the following?
E) 1,000 units
$25 - $10 = $15. $15,000/$15 = 1,000 units. - Correct Answers -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?
True - Correct Answers -The basic notion of economies of scale is that as a plant gets
larger and volume increases, the average cost per unit of output drops.
False - Correct Answers -A piece of equipment with twice the capacity of another piece
typically costs twice as much to purchase and to operate.
False - Correct Answers -The problem of keeping demand sufficiently high to keep a
large factory busy is a sales issue and not a diseconomy of scale.
C) 8,000 units
$50 - $35 = $15. $120,000/$15 = 8,000 units - Correct Answers -Assume a fixed cost
for a process of $120,000. The variable cost to produce each unit of product is $35, and
the selling price for the finished product is $50. Which of the following is the number of
units that has to be produced and sold to break-even?
B) The company's total margin will be less than its investment
Margin per unit = $30 - $15 = $15. $15 x 15,000 units = $225,000. Since $225,000 <
$256,000 the total projected margin for this product will be less than the investment
required. - Correct Answers -You are hired as a consultant to decide if your client
should purchase a new, highly specialized, piece of equipment. The product to be
produced by this equipment is forecast to have a total worldwide demand of 15,000
units over the entire product life. The initial investment to acquire and install the
