Facility location
Facility location A factory or a plant is the manufacturing
facility of a company. A warehouse is the storage facility of a
manufacturing or a distribution company. The offices of the service sector company
such as courier company, a bank or an insurance company are its facilities.
Facility location decision is very important for big business houses as well as new entrepreneurs. As wrong decision will lead to failure to complete project.
Facility set up without proper location planning
Sell off the facility to other Companies(Divestment)• Finding buyer at wrong location is difficult• Prices received after sell off are less as compared to earlier.• Divestment is time-consuming
Relocation to a new location• Only machine and equipment can be relocated not human resource•Capital expenditures are blocked•More investment is required to purchase land ,construction etc.
Closing of operations and liquidating the assets
• Liquidation of assets is time consuming and painful.• The price received after sell-off are usually much less than the actual investment made.
Continue operations at the existing location• Inherent problems at the location can also lead to low profit/ less market share.•Competitors having plants at better locations always have an edge.•In the long run company has to plan location at another facility to beta competition.

Location analysis Techniques
Dimensional analysisHere, relative merits of different costs such as transportationand power are considered for identifying the facility location.Its easy to select a plant site when all the costs are tangible and quantifiable in value.
IfC1
M , C2M, C3
M…..CZM are different costs associated
with a plant site, M on z different cost items.C1
N,C2N,C3
N…..CZN are different costs associated
with the plant site, N on Z different cost items.W1,W2,W3 are weight age given to cost items.
Value of relative merit of plant sites M and N is given by:
(C1M/C1
N)w1 * (C2M/C2
N)w2*………..(CzM/Cz
N)w3
If value of relative merit is >1, the plant site N is superior
Brown and Gibson method
This model considers three types of factors for analyzing the facility location
• Critical such as water for a refinery• Objective such as raw material costs• Subjective such as union activities
In the Brown and Gibson model, for each plant site ‘i’ a Loaction measure is calculated
LMi=CFMi*[D*OFMi=(1-D)*SFMi]Where,CFMi specifies the measure of critical factors for the plant site,i.Its value is either 0 or 1.
OFMi specifies the measure of objective factors for the plant site i(0<=OFMi<=1 and summation of OFMi)
SFMi specifies the measure of subjective factors for the plant site, i(0<=SFMi<=1 and summation of SFMi=1)
D specifies the objective factor decision weight (0<=D<=1).It represents the relative importance of theObjective factors to the subjective factors.
Hence, a plant site with higher value of location measure is preferred to the plant site with lower value of location measure.
Factor rating Method
• This is frequently used to evaluate locations because this method helps to figure out which location is better.
• This method enables managers to bring various locations into considerations in the evaluation process and thus it helps in identifying the most appropriate location for the plant.
How to do it???
• List down all the factors for evaluating the location• Each factor is rated from high value to low, which is usually 1 to 10,respectively.Rating hence is according to relative importance of the factor.
•Then there is the rating of location according to the characteristics and merits of each location.
• Finally the factor rating is multiplied by location rating to get the final results.
• The total of the product of factor rating and location rating specifies the most appropriate location.
For eg., for location A

Point rating Method
•This method involves an inspection of the importance of each factor in the location selection process. Each location factor is assigned a relative weight out of a maximum number of possible points, which is usually 100.
•Then a potential location is evaluated according to every factor considered by the management.
•A number of points are assigned to each factor.
•The location having the highest score is selected as the most suitable location.
Factor Unfavorable (0-33)
Average (34-66)
Favorable (67-100)

Break Even Analysis
Break even pointAt this point the cost of operations equals its revenues.
Break even analysis specifies the level of output that must be reached in order to recover all the cost of operations through revenues.
And the break-even point depends on the selling price of the product and the operating cost structure.
Cost is divided into two categoriesFixed cost: Doesn't vary with volume of production. For eg., salaries of staff, insurance.Variable cost: shipping handling cost etc.
Cost and revenue increases with increase in the volume of the output.
