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
you have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. the cyclle time of the line is 5 minutes and the sum of all the tasks required on the line is 25. which of the following is the correct value for the resulting line's efficiency?
0.833
you have just determined the actual number of workstations that will be used on an assembly line to be 4 using the assembly-line balancing procedure. the cycle time of the line is 10 minutes and the sum of all that tasks required on the line is 39 minutes. what is the value for the resulting line's efficiency?
0.97
Assume a fixed cost for a process of $120,000. The variable cost to produce each unit of product is $35, and the selling price for the finished product is $65. Which of the following is the number of units that has to be produced and sold to break-even?
4,000
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, 3, 7, 9, 6, and 5 minutes, and the cycle time is 7 minutes?
5
Using the assembly-line balancing procedure, which of the following is the required cycle time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?
9.6
which of these expressions is Little's Law?
ALL OF THE ABOVE
in a workcenter, machine a has a ten minute set-up per batch and a two minute per unit run time. machine b performs the identical function but has a set-up time of fifty minutes and a one minute run time per unit. the workcenter makes products in batches in batches ranging from one unit to one hundred units. Assuming capacity is not a limitation on either machine, on which batches should machine B be used?
Batches of more than 40 should be run on machine b
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
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 project layout is characterized by a low degree of task ordering
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
Dell computer is not an example of an assemble-to-order firm
FALSEe
The closer the customer is to the customer order decoupling point the shorter it takes the customer to receive the product.
TRUE
The first step in balancing an assembly line is to specify the precedence relationships among tasks to be performed on the line.
TRUE
Workstation cycle time is the time between successive units coming off the end of the assembly line.
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
engineer-to-order firms will work with the customer to design the product, and then make it from purchased materials, parts and components.
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
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
which of the following is not a step in developing a manufacturing cell layout?
disposing of left-over machinery and outsourcing ungrouped processes
break-even analysis can only be used in production equipment decision making when dealing solely with fixed costs, no variable costs
false
A firm fills its customer's orders from finished goods inventory. it is a:
make to stock firm
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, the theoretical minimum number of workstations is 5 using the assembly-line balancing procedure.
true
one trade-off illustrated by the product-process matrix is between flexibility and cost
true
assume a fixed cost for a process of $16, 015. the variable cost to produce each unit of product is $12 and the selling price for the finished product is $28. what is the number of units that has to be produced and sold to break-even?
1,000
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?
3
the focus in the make-to-stock environment is on providing finished goods where and when the customers want them
TRUE
the time needed to respond to a customer's order is called response time
false
