A worker is a basic production layout format in which similar equipment of functions are grouped together.

True

Assembly line balacing means assigning all necessary tasks to a series of workstations so that each workstation has no more than can be done in the the workstation cycle time and so that idle time across all workstations is minimized.

True

You have just determinined the actural number workstations that will be used on a assembly line to be 25 using the assembly line balancing procedure. the cycle time of the line is 30 seconds and the sum of all that tasks required on the line is 10 minutes. what is the line's efficiency?

.8 =80 %

You have just determined th actual number of workstations that will be used on an assembly line to be 8 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 60 minutes. which of the following is the correct value for the resulting line's efficiency?

0.750

using the assembly line balancing procedure, what is the required cycle time if the production time in minutes per day is 2,400 and the required output per day in units is 1,200?

2

using the assembly line balacing procedure, which of the following is the theoretical minimum number of workstations if the task time for the six tasks that make up the job are 4,6,7,2,6,5 minutes, and the cycle time is 10 minutes?

3

which of the following is not a step in developing a manufacturing cell layout?

Disposing of left-over machinery and outsourcing ungrouped processes

A manufacturing call groups the same or similar machines into cells to work on the products that have dissimilar shapes and dissimilar processing requirements

False

A project layout is similar to the basic production layout format of the work=center

False

If the sum of the task times required to produce a product is 80 minutes and the cycle time of the same product is 15 minutes, the theoretical minimum number of workstations is 8 using the assembly-line balancing producer.

False

Which of the following is not a basic type of production layout format?

Process layout

In assembley-line balancing the theoretical minimum number of workstations is found by ratio of the sum of all task times divided by the cycle time.

True

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.

True

if the required cycle time is 62 seconds, which of the following assignments rules will results in the lowest number of work stations?

both rules results in an equal number of work stations.

what is the theoretical minimum huber of work stations if the required cycle time is 62 seconds?

3.29

an assembly line is operated 7.5 hours per day and produces 400 units per day. following are the tasks that are performed with their performance time and preceding tasks. [compute the required cycle time]

67.5

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?

96

The efficiency of an assembly-line is found by ratio of the sum of all task times divided by the cycle time

False

using the assembly line balancing procedure, which of the following is the theoretical minimum number of workstations of the task times of the six task times of the tasks that make up the job are 7,4,7,5,3 and 6 minutes, and the cycle time is 8 minutes?
