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)

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

Graph-Based Method (Construction)
Nodes ? department Arcs ? common border
Numeric weights ? express relationship between
departments
Planar graph vs. non-planar graph?
