Service Location Decisions
Revenue focus
– Costs vary little between market areas
Location is a major revenue factor
– Affects amount of customer contact
production volume »Must be above break-even

Locational Break-Even Analysis Example
You’re an analyst for AC Delco. You’re considering a new manufacturing plant in Akron, Bowling Green, or Chicago. Fixed costs per year are $30k, $60k, & $110k respectively. Variable costs per case are $75, $45, & $25 respectively. The price per case is $120. What is the best location for an expected volume of 2,000 cases per year?
– Transportation cost »As much as 25% of product price
– Other costs: Taxes, wages, rent etc.
Objective: Maximize benefit of location to firm

Factor-Rating Method
Most widely used location technique Useful for service & industrial locations Rates locations using factors
Cost focus
– Revenue varies little between locations
Location is a major cost factor
– Affects shipping & production costs (e.g., labor)
– Costs vary greatly between locations
– Intangible (qualitative) factors
» Example: Education quality, labor skills
– Tangible (quantitative) factors »Example: Short-run & long-run costs

Example: Factor Rating Method
Method of cost-volume analysis used for industrial locations Steps
– Determine fixed & variable costs for each location – Plot total cost for each location – Select location with lowest total cost for expected
