Facility Location

Facility Location is the placement of facility with respect to
customers, suppliers and other interacting facilities. It
should consider:
»
»
»
»
Operating costs
Customer convenience
Transportation costs
Access to key related services
such as banking and
educational opportunities
» Strategic factors

Location as a Strategic Decision
1. Long-term commitment
2. Linked to customer base
3. Regional facility supplies specific area
4. Product facility supplies globally
5. Combination of regional and product facilities
Regional or Global
