provider is.
Assess the major issues that need to be
considered in locating a plant or warehouse
facility.
Learn how a factor-rating system can be
used to narrow potential location sites.
Set up the transportation model to analyze

Logistics
Logistics - the art and science of obtaining,
producing, and distributing material and
product in the proper place and in the proper
quantities
International logistics - managing these
functions when the movement is on a global
scale
Third-party logistics company - an outside
company used to manage all or part of
another company’s logistics functions

Factor-Rating System
Most widely used
List of factors is
developed
Range of possible points
assigned to each factor
Each site is rated against
each factor
The sums of assigned
points for each site are
computed
The site with the most
points is selected
Example – refinery location factors

Linear Programming –
Transportation Method
Transportation method is a special linear
programming method
Seeks to minimize costs of shipping n units to m
destinations or its seeks to maximize profit of
shipping n units to m destinations

Centroid Method
Used for locating single
facilities that considers
existing facilities, the
distances between them,
and the volumes of goods to
be shipped between them
Assumes inbound and
outbound transportation costs
are equal
Does not include special
shipping costs for less than a
full load
This methodology involves
formulas used to compute
the coordinates of the twodimensional point that meets
the distance and volume
criteria stated above
Cx =X coordinate of centroid
Cy =Y coordinate of centroid
dix =X coordinate of the ith
location
diy – Y coordinate of the ith
location
Vi – volume of goods moved to or
