Layout Procedures
Two main categories

• Construction-typeDevelop new layout from scratch
• Improvement proceduresGenerate layout
  alternatives based on existing layout

5
Apples Plant Layout Procedure

• Procure basic data
• Analyze basic data
• Design the productive process
• Plan material flow pattern
• Consider the general MH plan
• Calculate equipment requirements
• Plan individual workstations
• Select specific MH equipment
• Coordinate groups of related operations
• Design activity interrelationships

• Determine storage requirements
• Plan service and auxiliary activities
• Determine space requirements
• Allocate activities to total space
• Consider building types
• Construct master layout
• Evaluate, adjust, and check the layout with
  appropriate persons
• Obtain approvals
• Install the layout
• Follow up on implementation of the layout

Reeds Plant Layout Procedure
Systematic Plan of Attack

• Analyze the product(s) to be produced
• Determine process required to manufacture the
  product(s)
• Prepare layout planning charts
• Determine workstations
• Analyze storage area requirements
• Establish minimum aisle widths
• Establish office requirements
• Consider personnel facilities and services
• Survey plant services
• Provide for future expansion

• Layout Planning Chart
• Flow process, includes operations,
  transportation, storage, and inspection
• Standard times for each operation
• Machine selection and balance
• Manpower selection and balance
• Material handling requirements

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)
