Decisions in facility layout impact... [3]
|
production design, process design, and capacity.
|
|
|
What are the 5 reasons to redesign layout?
|
Inefficient operations.
Changes in product or service design. Introduction of new products or services. Changes in volume or mix of outputs. Changes in equipment. |
|
|
What are the 4 types of facility layouts?
|
Product layout.
Process layout. Fixed-position layout. Hybrid or combination layouts. |
|
|
When are product layouts used?
|
Standardized operations to achieve smooth, rapid, high-volume flow.
|
|
|
What are the 5 characteristics of product layouts?
|
Repetitive processing.
Smooth and rapid flow of large volumes of products or customers through a system. Highly standardized product or service. Job is divided into a series of standardized tasks. Permit specialization of labor and equipment. |
|
|
What are the advantages of a product layout design [6]?
|
1 high rate of output
2 low unit cost due to high volume 3 can spread high cost to specialized equipment over many units 4 labor specializaiton reduces training cost and time 5 low material-handling cost per unit 6 high utilization of labor and equipment |
|
|
What are 3 disadvantages of product layouts?
|
1 intensive labor division may create dull, repetitive jobs.
2 system may be inflexible in response to changes in volume of output or changes in product or process designs. 3 system is susceptible to shutdown caused by equipment breakdowns. |
|
|
Examples of process layouts.
|
Worker paced: Fast food restaurants.
Machine based: automatic car wash and automobile assembly. Customer paced: cafeteria line. |
|
|
2 Characteristics of machine pacing?
|
Moves at predetermined rate.
May lead to rushed workers and hence quality problems. |
|
|
Obstacles of product layout.
|
1 required Technological sequence
2 variability of task times 3 incompatibility of tasks. |
|
|
Process layouts are commonly used in...
Examples? |
service environments.
Hospitals, colleges, universities, banks, auto-repair shops, public libraries, airlines. |
|
|
What is the goal of line balancing?
|
To group tasks that are approximately equal time requirements to minimize idle time and yielding high equipment and work utilization.
|
|
|
Assembly line balancing,. The extent to which stations can be packed impacts...
|
Efficiency and the number of stations.
|
|
|
Assembly line balancing. What is cycle time C?
|
Time allowed at each work station.
Time between successive units coming off the line. Determines daily output capacity. |
|
|
Tie breaker heuristics [1]
|
Choose task with the largest number of following tasks.
Choose tasks with longest time. |
