Chronological list of facilities
planning and design activities
Early 1980s
The flexible manufacturing system concept is introduced and
attention shifts towards achieving plant-wide flexibility via
medium-volume, medium-variety production using cellular
manufacturing techniques
Late 1980s
The term automation introduced to cope with plant flexibility
requirements
1985-present
Modern software for facilities design problems
1990s-present
Research on new layout concepts including dynamic layouts,
robust layouts, and reconfigurable layouts introduced to support
mass customization techniques

Levels of decisions
• Strategic or Design or Long-term
• Planning or Intermediate
• Operational or short-term
Why is facilities layout important?
• 20-75% of product cost attributed to
materials handling (Sule, 1991 and
Tompkins et al. 2003)
• Layout of facilities affects materials
handling costs
• Facilities includes machines, departments,
workstations, locker rooms, service areas,
etc.
Why is facilities layout important?
• Good layout increases productivity
efficiency
• Reducing congestion permits smooth flow
of people and material
• Space utilization is effective and efficient
• Facilitates communication and supervision
• Safe and pleasant working environment
Constraints in developing facilities
layout
• Some pairs of departments must be
adjacent
• Some pairs of departments must not be
adjacent
• Some departments only in specific
locations
• Existing building constraints
• OSHA regulations, fire codes, etc.
Types of layout problems – Some
examples
• JIT manufacturer
• Relayout of an existing facility
• Relayout due to increased traffic (resulting from
a merger)
• Consolidation of manufacturing operations from
two or more sites to one
• Leasing of office space in a multi-story building
• Find a better layout in existing space
• Introduction of new product lines

Operations review for office layouts
(Suskind, 1989)
•
•
•
•
•
•
•
•
Is the company outgrowing its space?
Is available space too expensive?
Is building in the proper location?
How will a new layout affect the organization and
service?
Are office operations too centralized or decentralized?
Does the office structure support the strategic plan?
Is the new layout in tune with the company’s image
Does customer physically participate in service delivery?

Manufacturing layout
• Minimize transportation cost of raw materials,
sub-assemblies, work-in-process inventory,
tools, parts, finished products, etc.
• Facilitate traffic flow
• Improve employee morale
• Minimize or eliminate risk of injury and property
damage
• Ease of supervision and face-to-face
communication
