Littles Law can be thought of the relationship between units and time
TRUE
One difference between an assembly line process flow and a continuous flow is that an assembly line 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
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
TRUE
The objective of mixed model line balancing is to meet the demand for a variety of products and avoid building high inventories
TRUE
A make to order firm will work with the customer to design the product, and then make if from purchased materials
FALSE
A proses 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
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 in a facility depending on procedures
FALSE
The assembly line balancing procedure determines the precedence relationships of manufacturing tasks
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
Work center layouts allocate dissimilar machines into cells to work on products that have dissimilar processing requirements
FALSE
the closer the customer order decoupling point the longer it takes the customer to receive the product
FALSE
A continuous process indicates production of discrete parts moving from station to station at controlled rate
FALSE- continuous flow not discrete
The time needed to respond to a customers order is called the customer response time
FALSE- lead time
Which of the following is not considered a major work flow structure
Fabrication
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 supply chain process can be useful to understand how materials flow and where its 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
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
Engineer to order firms will work with the customer to design the product and then make it from purchased materials parts and components
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 layout a flexible line layout might have the shape of a U
TRUE
In designing a production line mixed-model line balancing might be used by JIT manufacturers
TRUE
The product process matrix shoes the relationship between process structures and product volume and variety characteristics
TRUE
The term assembly line refers to progressively assembly linked by some material handling device
TRUE
The volume requirement for the product are the one determinant of the choice of which process structure to select
TRUE
Workstation cycle time is the time between successive units coming off the end of the assembly line
TRUE
an example of assemble to order is Dell
TRUE
assembling to order means moving the customer order point from finished goods to components
TRUE
for the purpose of assembly line balancing, required work station cycle time is found by dividing the production time per day by the required units of output per day
TRUE
the focus in the make to stock environment is on providing finished goods where and when the customer wants
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- 45/10 = 4.5 round up to 5
give an example of a project layout
construction project- bridge
which of the following is not a step in developing a manufacturing cell layout
disposing of left over machinery and outsourcing ungrouped processes
the formula inventory = throughput rate x flow time is
littles law
when balancing an assembly line, which of the following is not a way to reduct the longest task time below the required cycle time
speed up the assembly line transfer mechanism
A difference between project and continuous flow categories of process flow structures is which two of the following
the size and bulk of the product
