Facilities Planning
 Facilities planning determines how an
activity’s tangible fixed assets best support
achieving the activity's objectives
4
Facilities Planning
Examples:
a. In manufacturing, the objective is to support
production.
b. In an airport, the objective is to support the
passenger airplane interface.
c. In a hospital, the objective is to provide medical care
to patients.

Facility Planning
Location
: is the placement of a facility with respect to
customers, suppliers, and other facilities with
which it interfaces.
Structure : consists of the building and services (e.g.,
gas, water, power, heat, light, air, sewage).
Layout
:consists of all equipment, machinery, and
furnishings within the structure.
Handling System :consists of the mechanism by which
all interactions required by the layout are
satisfied (e.g., materials, personnel,
information, and equipment handling systems).

Facility Planning Objectives
1. Support the organization's mission through improved
material handling, materials control, and good
housekeeping.
2. Effectively utilize people, equipment, space, and energy.
3. Minimize capital investment.
4. Be flexible and promote ease of maintenance.
5. Provide for employee safety and job satisfaction.
9
Issues in Facilities Design
 Minimize investment in new equipment
 Maximize production throughput rate
 Utilize space most efficiently
 Provide for the safety and comfort of employees
 Maintain a flexible arrangement
 Minimize materials handling cost
 Facilitate the manufacturing process
 Facilitate the organizational structure
10
Facility Plant Layout
 Facility layout: Arrangement of machines,
storage areas, and/or work areas usually within
the confines of a physical structure, such as a
retail store, an office, a warehouse, or a
manufacturing facility.
 for the location of all machines, utilities, employee
workstations, customer service areas, material
storage areas, aisles, restrooms, lunchrooms, internal
walls, offices, and computer rooms
 for the flow patterns of materials and people around,
into, and within buildings
11
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.
“You can make as many mistakes as you want in layout
planning, and they’ll all any for themselves if they avoid
mistakes in the physical installation”
12
Types of layout problems
Layout of a service system
Layout of a manufacturing facility
Warehouse layout
Nontraditional layout

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

Warehouse layout
29
Warehouse layout
Warehouse is a facility for storing merchandise,
commodities or other items
4 main warehouse functions
1. Receiving
2. Storing
3. Order picking
4. Shipping
30
Warehouse layout
• Where to locate
receiving and shipping
functions?
• Should the two
functions be combined
at one location or
separated?
31
Warehouse Layout Problem
Goal: utilize space effectively to minimize
storage and material handling cost(MHC).
32
Warehouse Layout Problem
Factor: shape and size of aisle,
warehouse height, location and orientation
of docking area, types of rack, storage &
retrieval automation
.
33
Warehouse Layout Problem
Shape and size of aisle factor
 MH equipment/ device
 Types of rack

Nontraditional layout
Keyboard layout
IC board layout
Computer disk storage layout
Airport gate layout

Non Traditional Layout Problem
Ex: Control panel LP in the design of a
computer backboard.
