This document provides an overview of manufacturing facility planning. It discusses the importance of facility planning, its objectives, and classification. The key steps in the facility planning process are also outlined. These include defining objectives, specifying activities, determining relationships between activities, establishing space requirements, generating and evaluating alternative plans, selecting and implementing a plan, and maintaining/adapting the plan over time. The target audience is 4th year students studying manufacturing facility planning.

4. 1. Introduction to facility planning
What is Facility ?
• A facility is an entity(object) that facilitates
the performance of any job.
• Example Machine, tool, work center,
manufacturing cell, warehouse, land, buildings,
equipment, furnishings and etc.

5. What is Facility Planning?
Facility Planning determines how an activity’s tangible fixed assets
best support in achieving the activity’s objectives.
Examples:
a. In manufacturing, the objective is to support production.
(manufacturing facility Planning)
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.

8. 1. Facility location : is the placement of a facility
with respect to customers, suppliers,
and other facilities with which it
interfaces.
2. Structure Design: consists of the building
and services (e.g., gas, water system,
lighting system, air conditioning system,,
sewage system, safety system, etc. )
8

9. 3. Layout Design: consists of all equipment,
machinery, and furnishings within the
structure.
4. Handling System Design: consists of the
mechanism by which all interactions
required by the layout are satisfied
(e.g., materials, personnel, information,
and equipment handling systems).

11. Why is Facility planning important?
1) Facility planning must be a continuing activity to be
competitive and keep developments in its field.
• Economic considerations of existing systems,
personnel and equipment
• New machines and processes
• Rapid changes in production techniques in the
present and future
11

12. 2) Facility planning can increase plant productivity and
reduce costs by reducing or eliminating all activities
that are unnecessary and wasteful.
3) By incorporating vital health and safety measures
the employer may avoid unsafe conditions and losses
in both money and manpower resulting from industrial
accidents.
12
Why is Facility planning important?
Cont..

13. 4) Energy conservation incorporating new methods of
energy to reduce the cost of energy
5) Other factors that requires investment in new facilities
Example
• Fire protection ,Security, Disability act
• Community rules and regulations regarding noise ,air
pollution, liquid and solid waste disposal.
6) Pilferage- stealing merchandise from manufacturing
companies etc…

14. 2. Objectives of Facility planning
o Minimize capital investment & increase productivity
o Improve customer satisfaction
o Effectively utilize people, equipment ,Space and energy
o Improved material handling, material control and good
house keeping.
o Promote flexibility & increase speed to customer
response (shorten lead time)
o Provide for employee safety and job satisfaction
o Improve productivity and reduce costs

15. 3. Classification of Facility Planning
• It is important to organize and classify facility planning
into manageable sub-projects based on their Levels of
Detail.
• Each sub-project has a series of tasks that the design
team must complete.
• The tasks and their sequence differ for each level
15

16. Facility planning levels of details
I. Global (Site Location)
This involves factors such as freight cost, labor cost, skill
availability and site focus.
II. Supra (Site Planning)
This includes number, size, and location of buildings. It includes
infrastructure such as roads, water, gas and rail.
III. Macro (Building Layout)
Operating departments are defined and located at this level.
Frequently, this is the most important level of planning. A Macro-
Layout institutionalizes the fundamental organizational structure
in steel and apparel industry.
16

17. Facility planning levels of details cont..
IV. Micro (Work cell/Department
Layout)
determines the location of specific equipment and
furniture
V. Sub-Micro (Workstation Design)
focuses on individual workers. Here we design
workstations for efficiency, effectiveness and
safety. Ergonomics is key.

19. 4. Facility planning process steps
1) Define or redefine the objective of the facility
2) Specify the primary and support activities to be performed in
accomplishing the objective
3) Determine the interrelationships among all activities
4) Determine the space requirement for all activities
5) Generate alternative facility plans
6) Evaluate alternative facility plans
7) Select a facilities plan
8) Implement the facilities plan
9) Maintain and adapt the facility plans
10) Redefine the objective of the facilities
19

20. 1) Define or redefine the objective of the facility
• May be planning for new facility or improvement of
existing facility.
• Products to be produced or services to be provided
must be specified quantitatively
• Volumes or levels of activities are to be identified
when possible.
20

21. 2) Specify the primary and support activities to be
performed in accomplishing the objective
• Primary and support activities to be performed and
should be specified in terms of operations ,equipment
,personnel and material flow involved.
• Support activities allow primary operations to
function properly with out interruptions.
e.g Maintenance function is a support activity for
manufacturing.
21

22. 3) Determine the interrelationships among all activities
• Define both quantitatively and qualitatively how
activities interact and support one another with in the
boundaries of the facility.
4) Determine the space requirement for all activities
• All equipment , material, and personnel requirements
must be considered while considering space
requirements for each activity.
22

23. 5) Generate alternative facility plans
• Alternative facility plans will include both alternative
facility locations and alternative facility designs.
• Alternative facility designs will include alternative
layout design, structural designs and material handling
system designs.
• Depending on the situation the facility location decision
and facility designs may be decoupled
23

24. 6) Evaluate alternative facility plans
• Determine the factors, set an accepted criteria and
rank the plans.
7) Select a facility plans
• Select the most acceptable in satisfying the goals and
objectives of the organizations.
• Most often cost is not the only major considerations
when evaluating a facility plans.
• Use the information generated in step 6.
24

25. 8) Implement the facility plans
• After selection, considerable amount of planning must
precede before the actual construction of the facility.
• Supervising installation of layout, getting ready to
start up, actual starting up, running and correction
activities are all part of implantation phase of facility
planning.
25

26. 9) Maintain and adapt facilities plans.
• When new requirements are placed on the facility, the
facility plan must be modified accordingly.
• Changes in product design, new machines ,material
handling equipments or flow patterns require an
updated facility plan.
10) Redefine the objective of the facility
• In case of potential modifications ,expansion and so on
for existing facilities, all recognized changes must be
considered and the objective of the facility should be
redefined in quantifiable terms 26

27. Brainstorming
• Think about your role as a facility
planner and what kind of
improvements would you like to
suggest for garment industries.
