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
