OPMA Exam 2 - chp 6. T/F
A continuous process indicates production of discrete parts moving from workstation to workstation at a controlled rate.
False
A make-to-order firm will work with the customer to design the product, and then make it from purchased materials, parts, and components.
False
A process map shows the physical location of the various processes within a supply chain.
False
Break-Even Analysis can only be used in production equipment decision making when dealing solely with fixed costs, no variable costs.
False
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.
False
In balancing an assembly line, workstation cycle time has to be less than the time between successive units coming off the end of the line.
False
Process selection refers to the strategic decision of choosing the volume of output to produce in a manufacturing facility depending upon the way that facility produces
False
The assembly-line balancing procedure determines the precedence relationships of manufacturing tasks.
False
Workcenter layouts allocate dissimilar machines into cells to work on products that have dissimilar processing requirements.
False
The volume requirements for the product are one determinant of the choice of which process structure to select.
TRUE
In designing a production layout a flexible line layout might have the shape of a "U".
True
A general purpose machine is less capable than a special purpose machine in certain tasks but can perform a broader variety of tasks.
True
A high-level map or diagram of a supply chain process can be useful to understand how material flows and where inventory is held
True
A project layout is characterized by a high degree of task ordering.
True
A project layout is characterized by a relatively low number of production units in comparison with process and product layout formats.
True
An example of an assemble-to-order firm is Dell Computer.
True
Assembling-to-order means moving the customer order decoupling point from finished goods to components.
True
Break-Even Analysis can be used to help decide whether to perform a task with a special purpose machine or with a general purpose machine.
True
One difference between an assembly line process flow and a continuous process flow is that on the assembly line the flow is discrete rather than continuous.
True
One methodology used to evaluate equipment investment decisions where the investment entails an initial investment, fixed costs, and variable costs is Break-Even Analysis.
True
One trade-off illustrated by the product-process matrix is between flexibility and cost
True
Process selection refers to the strategic decision of selecting which kind of production processes to use to produce a product or provide a service.
True
The closer the customer is to the customer order decoupling point the more quickly the customer receives the product.
True
The essential issue in satisfying customers in the make-to-stock environment is to balance the level of finished inventory against the level of service to the customer.
True
The first step in balancing an assembly line is to specify the precedence relationships among tasks to be performed on the line.
True
The focus in the make-to-stock environment is on providing finished goods where and when the customers want them.
True
The objective of mixed-model line balancing is to meet the demand for a variety of products and avoid building high inventories.
True
The product-process matrix shows the relationship between process structures and product volume and variety characteristics.
True
The term "assembly line" refers to progressive assembly linked by some material handling device.
True
Workstation cycle time is the time between successive units coming off the end of the assembly line.
True
Little's law states that supply chain processes can be regarded as unrelated and thus treated and analyzed separately.
False
The closer the customer is to the customer order decoupling point the longer it takes the customer to receive the product.
False
The efficiency of an assembly-line is found by a ratio of the sum of all task times divided by the cycle time.
False
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
The time needed to respond to a customer's order is called the customer response time.
False
Engineer-to-order firms will work with the customer to design the product, and then make it from purchased materials, parts, and components.
True
For the purposes of assembly-line balancing, the required workstation cycle time is found by dividing production time per day by the required units of output per day.
True
If the sum of the task times required to produce a product is 45 minutes and the cycle time for the same product is 10 minutes. Thus, the theoretical minimum number of workstations is 5 using the assembly-line balancing procedure.
True
In assembly-line balancing the theoretical minimum number of workstations is found by a ratio of the sum of all task times divided by the cycle time
True
In designing a production line mixed-model line balancing might be used by JIT manufacturers.
True
Little's law can be thought of as a relationship between units and time.
True
