1. Facility Location COB 300C – Fall 2002

2. Facility Location 4 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

3. 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

4. Factors Affecting the Location Decision 4 Strategic nature of decision 4 Quantitative factors 4 Government incentives 4 Qualitative factors

5. Including the Qualitative Factors 4 Integrate qualitative factors –Determine which factors are relevant to the problem –Weigh each factor –Rate each site for each factor

8. Analyzing Spatial Relationships l Load-Distance Method measures proximity to customers, suppliers, interacting facilities l Transportation Problem relates to the cost of transporting materials to and from multiple facilities

9. Distance from Facility to Customer

10. Health Care Unit Location Problem

11. Locating a Health Care Center Using the “Load-Distance Method” (Slide 1 of 3) Population coordinates Code a i x i y i (a i )(x i ) (a i )(y i ) 10111 30,000 3 2 90,000 60,000 10112 25,000 2 4 50,000 100,000 10113 11,000 1.5 5.5 16,500 60,500 10114 8,000 3 7 24,000 56,000 10115 18,000 3.5 5 63,000 90,000 10116 24,000 4.5 3.5 108,000 84,000 10117 12,000 5.25 6.25 63,000 75,000 Total 128,000 414,500 525,500 Zip

12. Locating a Health Care Center Using the “Load-Distance Method” (Slide 2 of 3) where xf = Distance along the x axis from the origin to the center of gravity yf = Distance along the y axis from the origin to the center of gravity a i = The activity level (load) from the i th location to the proposed facility X i = the coordinate on the x axis for the i th customer location y i = the coordinate on the y axis for the i th customer location

13. Locating a Health Care Center Using the “Load-Distance Method” (Slide 3 of 3) The coordinates of the center of gravity are: xf = yf = 414,500 525,500 128,000 128,000 = 3.24 = 4.11

14. Transportation Problem 4 Cost of moving materials between multiple destinations 4 Vogel’s Approximation Method 4 To evaluate two locations, solve the transportation problem for each location OR

15. Transportation Example 4 New facility capacity = 5000 units/month 4 We must choose either Des Moines, Iowa or Montgomery, Alabama 4 Transportation costs per unit for Des Moines and Montgomery to each customer location are provided 4 We are interested in total transportation cost for Des Moines versus Montgomery

16. Transportation Example (cont’d) 4 Supply Lexington - 12,420 Milan - 9,380 DesMoines - 5,000 (proposed) or Montgomery - 5,000 (proposed)

17. Transportation Example (cont’d) 4 Demand Baton Rouge - 6,740 Bismarck - 8,400 Tampa - 5,050 Youngstown - 5,670

34. Total Transportation Cost for Des Moines 6740($14)+4740($16)+940($0)+3400($15)+ 310($17)+5670($9)+5000($11) = $332,500

35. For Next Class Figure Transportation Cost for Montgomery 4 Which is best choice based on Vogel’s Approximation? 4 Are there other factors to consider? 4 Montgomery’s Transportation Costs: –Montgomery to Baton Rouge: $9 per unit –Montgomery to Bismarck: $19 per unit –Montgomery to Tampa: $12 per unit –Montgomery to Youngstown $15 per unit

36. Location Example - Load Distance 4 Location of a warehouse in Germany 4 Method: Load-Distance Method (a.k.a.: center-of-gravity method) 4 Customer locations (coordinates) and demands in units per year are given

41. Show map here

42. Location? 4 Central Germany

43. Other Factors to Consider? 4 operating costs 4 required investment 4 government incentives 4 qualitative factors 4 overall strategy of organization

44. Location Decision Affects Other Operating Decisions 4 Alternative to on-site expansion 4 On-site expansion is problematic –Material handling and storage –Complex production flow –Strained communication –New technology delayed –Use of old equipment –Layering of expanded responsibilities

45. International Dimensions of Location Decision 4 Reasons for locating in foreign countries –Comparative Advantage –Closeness to market –Political relationships –Availability of resources

46. Location Analysis for Service Operations l Concepts and techniques discussed so far apply to service operations l Service issues : »Minimize response time: Emergency medical services »Provide minimum coverage: Fire Protection »Mobile location: Police or security units
