1. Traditional Approaches to Facility Layout
Chapter 4

2. Significance of Facilities Planning
20-50% of all manufacturing costs are related to material handling
FP can reduce MH costs by 10-30%
Therefore…
2-15% reductions in overall manufacturing costs could be achieved by effective facilities planning.
Annual productivity would increase 3x more than it has in the past 15 years.
Hard to make similar projections to other areas of our economy
FP continues to be one of the most promising fields

3. Objectives Minimize material handling costs Utilize space efficiently
Utilize labor efficiently
Eliminate bottlenecks
Facilitate communication and interaction between workers, between workers and their supervisors, or between workers and customers
Reduce manufacturing cycle time or customer service time

4. Objectives (continued)
Eliminate waste or redundant movement
Facilitate the entry, exit, and placement of material, products, or people
Incorporate safety and security measures
Promote product and service quality
Encourage proper maintenance activities
Provide a visual control of operations or activities
Provide flexibility to adapt to changing conditions
Increase capacity

5. The Nature of FP Objectives
As you can see, there are MANY!
They are conflicting. How?
There are constraints. Can you list some?

6. The Facility Planning Problem
It is a constrained multi-objective optimization problem with many non-quantifiable costs and benefits.
There is NO OPTIMAL SOLUTION!
The best we can hope for is a “GOOD” solution.
Effective designs must consider all stakeholders
Owners
Customers
Suppliers
Employees
Neighbors

7. Layout Problems
Design or Optimization?

8. Facility Design Process
Combination of art and engineering
Many techniques available
Muther’s SLP Approach (1973)
Optimization based approaches
We will focus on both

9. Systematic Layout Planning
Phase I - Determination of the location of the area where departments are to be laid out
Phase II - Establishing the general overall layout
Phase III - Establishing detailed layout plans
Phase IV - Installing the selected layout

11. Systematic Layout Planning
P Product: Types of products to be produced
Q Quantity: Volume of each part type
R Routing: Operation sequence for each part type
S Services: Support services, locker rooms, inspection stations, and so on
T Timing: When are the part types to be produced ? What machines will be used during this time period?

13. Special Considerations in Office Layout
Minimizing distance traveled by employees
Permitting flexibility so that the current layout can be changed, expanded or downsized easily
Providing a safe and pleasant atmosphere for people to work in
Minimizing capital and operational costs of the facility
