Line Balancing

The Production rate of an assembly line is determined by its

• Slowest station

• Fastest station

• Idle station

• None of these

General principles of Design For Assembly includes

• Use the fewest number of parts possible to reduce the amount of assembly required

• Reduce the number of threaded fasteners required

• Standardize fasteners

• Reduce parts orientation difficulties

• All of the above

Which is referred to as the bottleneck station

• Lead time for the entire line

• cycle time for the one station

• cycle time for the entire line

• Lead time for the one station

Maximum service time must be

• No greater than the difference between the cycle time Tc and the repositioning time Tr

• Greater than the difference between the cycle time Tc and the repositioning time Tr

• Greater than the cycle time Tc and less than repositioning time Tr

• Greater than the repositioning time Tr and less than cycle time Tc

Cycle time is not:

• daily operating time divided by desired production

• the maximum allowable time at each work station

• how often items roll off the assembly line

• the time required to complete a product from start to finish

An assembly line consists of 5 tasks with times of 12, 9, 8, 7, and 11 minutes. The cycle time for the line is 25 minutes. The theoretical minimum number of workstations for this situation is

• 1

• 2

• 3

• 4

• 5

The process of equalizing the amount of work at each workstation is called precedence diagramming.

• True

• False

For an assembly line if balance delay is high then efficiency will be low and vice versa.

• True

• False

Automation is preferred because it:

• Offers lesser dependence on workers

• Results in reduction in variable cost

• Offers easy handling of repetitive work

• All of the above

Balanced Assembly line effects in

• Minimizes Wastes

• Minimizes Idle time

• Reduces Variation

• Increases Effeciency

• All the above
