UNIT 3 QUIZ MG 375 Correct answers are hidden. Score for this attempt: 18 out of 25 * Submitted Dec 9 at 6:34pm This attempt took 14 minutes. Question 1 1 / 1 pts A continuous process indicates production of discrete parts moving from workstation to workstation at a controlled rate. True False A continuous process is similar to an assembly line in that production follows a predetermined sequence of steps, but the flow is continuous such as with liquids, rather than discrete. Question 2 1 / 1 pts The assembly-line balancing procedure determines the precedence relationships of manufacturing tasks. True False The assembly-line balancing problem is one of assigning all tasks to a series of workstations so that each workstation has no more than can be done in the workstation cycle time, and so that the unassigned (that is, idle) time across all workstations is minimized. The problem is complicated by the relationships among tasks imposed by product design and process technologies. This is called the precedence relationship, which specifies the order in which tasks must be performed in the assembly process. Question 3
1 / 1 pts In designing a production layout a flexible line layout might have the shape of a "U". True False Assembly-line balances frequently result in unequal workstation times. Flexible line layouts are a common way of dealing with this problem. A U- shaped line with work-sharing could help resolve the imbalance. Question 4 1 / 1 pts According to Little's Law, which of the following ratios is used to find throughput rate? A) Cycle time/Process time B) Throughput time/Process velocity C) Process velocity/Throughput time D) Inventory /Flow time E) Value added time/Process velocity A B C D
E Simple systems can be analyzed quickly using a principle known as Little's law. Little's law says there is a long-term relationship between the inventory, throughput, and flow time of a production system in steady state. The relationship is: Inventory = Throughput rate × Flow time. Thus, Throughout Rate = Inventory/Flow Time. Question 5 1 / 1 pts Which of the following is not a step in developing a manufacturing cell layout? Grouping parts into families that follow a common sequence of steps Identifying dominant flow patterns of parts families as a basis for location of processes Physically grouping machines and processes into cells Disposing of left-over machinery and outsourcing ungrouped processes disposing and outsourcing is not part of this development. Question 6 1 / 1 pts Little's law states that supply chain processes can be regarded as unrelated and thus treated and analyzed separately. True False

We can think of Little's law as a relationship between units and time. Question 7 1 / 1 pts The product-process matrix shows the relationship between process structures and product volume and variety characteristics. True False C = , Product–Process Matrix: Framework Describing Layout Strategies Question 8 1 / 1 pts Which of the following is not a basic type of process structure? A) Product-process matrix B) Workcenter C) Manufacturing cell D) Assembly line E) Continuous process A B C D
E The formats by which a facility is arranged are defined by the general pattern of work flow; there are five basic structures (project, workcenter, manufacturing cell, assembly line, and continuous process). Question 9 1 / 1 pts Which of the following basic types of process structures is one which similar equipment or functions are grouped together? A) Project B) Workcenter C) Manufacturing cell D) Assembly line E) Continuous process A B C D E A workcenter layout is where similar equipment or functions are grouped together. Question 10
1 / 1 pts Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes? A) 3 B) 5 C) 6 D) 8 E) None of these A B C D E Nt = , (4 + 6 + 7 + 2 + 6 + 5) / 10 = 3. Question 11 1 / 1 pts If the sum of the task times required to produce a product is 80 minutes and the cycle time for the same product is 15 minutes, the theoretical minimum number of workstations is 8 using the assembly-line balancing procedure. True

False Nt = : 80 minutes / 15 minutes = 5.3, round up to 6. Question 12 1 / 1 pts A firm fills its customer's orders from finished goods inventory. It is a: A) make to order firm. B) engineer to order firm. C) make to stock firm. D) customer service firm. E) assemble to order firm. A B C D E Firms that serve customers from finished goods inventory are known as make-to-stock firms. Question 13 1 / 1 pts The "service blueprint" is a classification of services.
True False : Just as is the case with manufacturing process design, the standard tool for service process design is the flowchart. Recently, the service gurus have begun calling the flowchart a service blueprint to emphasize the importance of process design. Question 14 1 / 1 pts The customer arrivals in a queuing system come almost exclusively from finite populations. True False Arrivals at a service system may be drawn from a finite or an infinite population. The distinction is important because the analyses are based on different premises and require different equations for their solution. Question 15 1 / 1 pts Which of the following is considered a high-contact service operation? A) On-line brokerage house B) Internet sales for a department store C) Physician practice D) Telephone life insurance sales and service E) Automobile repair
A B C D E Question 16 1 / 1 pts Buying a ticket for a college football game where there are multiple windows to buy the ticket at features which type of queuing system line structure? Single channel, single phase Single channel, multiphase Multichannel, single phase Multichannel, multiphase Definition of Waiting line models Incorrect Question 17 0 / 1 pts

Every service has a service package, which is defined as a bundle of goods and services provided in some environment. The service package consists of five features. Which of the following is not one of these features? Supporting facility Facilitating services Explicit Services Implicit Services See the Nature of Services Incorrect Question 18 0 / 1 pts Which of the following are the three major components of a queuing system? A) The source population, how customers exit the system, and the queuing discipline. B) The number of servers, the service speed and the waiting line. C) The source population, how the customer exits the system, and the servicing system. D) The source population and the way customers arrive at the system, the serving systems, and how customers exit the system. E) The service speed, the queue discipline and the waiting line. A B
C D E Question 19 1 / 1 pts A service system with a high degree of customer contact is less difficult to control than a low degree of customer contact service system. True False Service systems with a high degree of customer contact are more difficult to control than those with a low degree of customer contact. Question 20 1 / 1 pts A car wash is an example of a single channel, multiphase queuing system. True False Single channel, multiphase. A car wash is an illustration because a series of services (vacuuming, wetting, washing, rinsing, drying, window cleaning, and parking) is performed in a fairly uniform sequence. Question 21
Not yet graded / 5 pts Describe the service package of Park University Your Answer: In addition to your degree, your institution may provide other services. If you live on campus, you're taking use of the facilities provided by your university by virtue of your residency status. Alternatively, you may order your books from the campus bookstore or have them delivered directly to your residence hall. You may dine on campus if the dining facilities are contracted out to outside food service providers. An additional amenity offered is the use of a public library. The building's upkeep, snow removal, and after-hours cleaning are just a few of the less evident services that are provided. The service package for your school could be extended beyond the degree you will earn. If you are a resident on the campus, you are using the housing that is offered by your school. Additionally, you are able to buy all your books at the book store on the campus or your school ships them to you. Dining facilities are often contracted out to food service companies so you can eat on campus. The library is another service that is provided. Less obvious services include the maintenance of the building, clearing the parking lot of snow, cleaning the building after hours.
