Title: Systematic Layout Planning SLP Procedure


1
Systematic Layout Planning (SLP) Procedure
Proposed by Muther (1973)
  • Based on activity relationship chart (chapter 4)
  • Material flow analysis from-to chart
  • Activity relationship analysis REL chart
  • Output Relationship diagram (REL diagram)

2
SLP framework
2. Activity Relationships
1. Flow of materials
Analysis
3. Relationship diagram
5. Space available
4. Space requirements
6. Space relationship diagram
8. Practical limitations
7. Modifying considerations
Search
9. Develop layout alternatives
Selection
10. Evaluation
3
Algorithmic Approaches
Variation of SLP Ideas by Apple
  • Relationship Diagramming
  • Pairwise Exchange Method
  • Graph-Based Construction Method

CRAFT Travel Chart Method
Graph Theory
4
Relationship Diagramming (Construction)
Department Area (Number of Unit Area Templates)
Relationship Diagramming Worksheet
Iterate

Locate Block Template
Activity Relationship Chart
Expand
Final Block Layout
5
Pairwise Exchange Method (Improvement)
Existing Layout
Improve the layout
What is the measure of improvement?
One possibility Minimize the total cost of
transporting materials among all departments in a
facility
Material Flow Matrix
Pairwise exchange of departments
Compute the cost of the new layout

Distance Matrix based on existing layout
6
Graph-Based Method (Construction)
Nodes ? department Arcs ? common border
Numeric weights ? express relationship between
departments
Planar graph vs. non-planar graph?
