Assembly Line
Which of the following describes the layout used for a dedicated area where a group of similar products are produced?
Manufacturing Cell
The first step in analyzing the flow of material through a production process is known as process mapping
True
The performance metric that measures the average time for a unit to move through a system is which of the following:
Flow Time
The product-process matrix describes production process selection based upon product volume and the level of product standardization.
True
Workcenter layouts allocate dissimilar machines into cells to work on products that have dissimilar processing requirements
False
The closer the customer is to the customer order decoupling point, the longer it takes the customer to receive the product
False
Assembling-to-order means moving the customer order decoupling point from finished goods to components.
True
Engineer-to-order firms will work with the customer to design the product, and then make it from purchased materials, parts, and components.
True
The essential issue in satisfying customers in the make-to-stock environment is to balance the cost of the finished item against the willingness of the consumer to pay for it
False
According to Little’s law, which of the following can be used to estimate work-in-process inventory?
Throughput rate times Flow time
Special purpose (i.e. dedicated) equipment is used in assembly line
True
Throughput rate is defined as the maximum rate that work can be produced by the entire process.
False
Valley Forge Income Tax Advice (VIF) is a small accounting firm supporting wealthy individuals in their preparation of annual income tax statements. In order to prepare the income tax statement, VIF needs to complete the following set of activities in sequence. Each step (activity) is performed by one person. All of the following activity times are expressed in minutes per income tax statement.
Filing: 20; Initial Meeting: 30; Preparation: 120; Review: 20; Writing : 50
Which step is the bottleneck?
Preparation - 120
Filing: 20; Initial Meeting: 30; Preparation: 120; Review: 20; Writing : 50
Given the information in Q1, what is the maximum number of tax statements that can be completed within eight hours?
Given the fact that the bottleneck can finish one statement every 2 hours, the maximum number of statements that can be completed in eight hours = 8/2=4.

In a steady state, on average every two hours one client comes in. A secretary takes over the writing task and reduces the time to write an income tax statement by 50% by using a new word processing system. With this change along with the information provided in Q1, which of the following statement(s) is true?
I: Process capacity is increased.
II The utilization of this secretary is 20.8%.
2 only
The utilization of the writing step = throughput rate/capacity of this step. The capacity of the writing step = 60/25 = 2.4 per hour. Therefore the utilization is 20.8% = 0.5/2.4
The video store manager at Family Video was interested in determining the traffic in his store. He conducted a study and found that on average 6 customers left his store per hour. He also found that on average 2 customers were in his store at any time. (Assuming these findings describe what happen in the steady state.)
What can you conclude based upon these findings?
The throughput rate of this system is 6 customers per hour
Based up the findings reported in the previous question, what can you conclude?
On average customers spent 20 min in the store.
Family Vision makes customized eyeglasses. Each pair of glasses is uniquely made and carefully fit to individual’s eyes. Which of the following best describes the type of manufacturing process in Family Vision?

Caterpillar makes more than 20 different types of machinery with low volume. Which of the following best describes Caterpillar’s production process?
Work Center
According to the information from the previous question, general purpose (i.e. flexible) equipment rather than special purpose (i.e. dedicated) equipment is used in Caterpillar’s production process.
True
Dell’s assembly plant makes computers by combining pre-assembled modules to meet a customer’s specifications. Which of the following is NOT one of the major challenges associated with this manufacturing process?
Balance the finished good inventory against the level of customer service
According to the information about Dell in the previous question, where is the customer order decoupling point in this process?
The work-in-process inventory at the manufacturing site
