OSCM 303 CHAPTER 16 QUIZ + STUDY

T or F The minimum number of workstations depends upon the set of task times and the precedence chart, but not the number of units scheduled.

False

T or F One drawback of a product-oriented layout is that work stoppage at any one point ties up the whole operation.

True

T or F If the schedule calls for the production of 120 units per day and 480 minutes of production time are available per day, the cycle time would be 4 minutes.

True

An assembly line consists of 21 tasks grouped into 5 workstations. The sum of the 21 task times is 85 minutes. The largest assigned cycle time is 20 minutes. What is the efficiency of this line? 4.2 percent 100 percent 85 percent 21 percent 17 percent

85 percent efficiency = total task time/ (cycle time* # of workstations)

Which of the following is a disadvantage of product-oriented layout? There is a lack of flexibility necessary for handling a variety of products. High volume is required because of the large investment needed to establish the process. Work stoppage at any one point can tie up the whole operation. There is a lack of flexibility necessary for handling a variety of production rates. All of these are disadvantages of product-oriented layouts.

All of these are disadvantages of product-oriented layouts.

Which one of the following is not common to repetitive and product-oriented layouts? a. a high rate of output b. specialization of labor c. ability to adjust to changes in demand d. low unit costs e. All are common to product-oriented layouts.

c. ability to adjust to changes in demand

Cycle time is computed as: a. daily operating time divided by the product of desired output and the sum of job times. b. the product of desired output and the sum of job times divided by daily operating time. c. 1.00 minus station time. d. daily operating time divided by the scheduled output. e. desired output divided by the daily operating time.

d. daily operating time divided by the scheduled output.

Which of the following is a common heuristic for assembly line balancing? a. debits near the windows, credits near the door b. manufacturers locate near materials, retailers locate near customers c. earliest due date first d. ranked positional weight

d. ranked positional weight

Cycle time is computed as

daily operating time divided by desired output

A good layout requires determining: a. material handling requirements b. capacity and space requirements c. environment and aesthetics d. cost of moving between various work areas e. all of the above

e. all of the above

The main advantage of a product-oriented layout is typically: a. low raw material cost b. employability of highly skilled labor c. high flexibility d. low capital cost e. low variable cost per unit

e. low variable cost per unit

One of the major advantages of process-oriented layouts is: a. high equipment utilization b. large work-in-process inventories c. flexibility in equipment and labor assignment d. smooth and continuous flow of work

flexibility in equipment and labor assignment

The typical goal used when developing a process-oriented layout strategy is to: a. minimize the distance between adjacent departments b. minimize the material handling costs c. maximize the number of different tasks which can be performed by an individual machine d. minimize the level of operator skill necessary

minimize the material handling costs

A production line is to be designed for a product whose completion requires 21 minutes of work. The factory works 400 minutes per day. Can an assembly line with five workstations make 100 units per day? yes, with exactly 100 minutes to spare no, but four workstations would be sufficient no, it will fall short even with a perfectly balanced line yes, but the line's efficiency is very low cannot be determined from the information given

no, it will fall short even with a perfectly balanced line

In assembly line balancing, the minimum number of workstations is:

the ratio of the sum of all task times to cycle time sum of all task times / cycle time

The assumptions necessary for a successful product-oriented layout include all EXCEPT which of the following? adequate volume for high equipment utilization standardized product volatile product demand adequately standardized supplies of raw materials and components All of these are appropriate assumptions.
