Multiple Plant Strategies Process plant strategy Ø Different plants focus on different aspects of a process Ø automobile manufacturers – engine plant, body stamping plant, etc. Ø Coordination across the system becomes a significant issue Ø General-purpose plant strategy Ø Plants are flexible and capable of handling a range of products Ø 28
Service and Retail Locations Ø Nearness to raw materials is not usually a consideration Ø Customer access is a ØPrime consideration for some: restaurants, hotels, etc. ØNot an important consideration for others: service call centers, etc. Ø Tend to be profit or revenue driven, and so are ØConcerned with demographics, competition, traffic/volume patterns, and convenience 29
Evaluating Location Alternatives Common techniques for location evaluation: Ø Locational cost-volumeprofit analysis Ø Factor rating method Ø Load-distance method Ø Center of gravity method Ø Transportation model (a specialized linear programming method) 30
Locational Cost-Profit-Volume Analysis 31
Locational Cost-Profit-Volume Analysis Locational Cost-Profit-Volume (Break-even)Analysis Ø A technique for evaluating location choices in economic terms Ø Steps: 1. Determine the fixed and variable costs for each alternative 2. Plot the total-cost lines for all alternatives on the same graph 3. Determine the location that will have the lowest total cost (or highest profit) for the expected level of 32 output
Locational Cost-Profit-Volume Analysis Assumptions 1. Fixed costs are constant for the range of probable output 2. Variable costs are linear for the range of output 3. The required level of output can be closely estimated 4. Only one product is involved 33
Locational Cost-Profit-Volume Analysis For a cost analysis, compute the total cost for each alternative location: 34
Example: Cost-Profit-Volume Analysis Fixed and variable costs for four potential plant locations are shown below: Location Fixed Cost per Year Variable Cost per Unit A $250, 000 $11 B $100, 000 $30 C $150, 000 $20 D $200, 000 $35 35
Example: Cost-Profit-Volume Analysis Comparison of total costs at a production volume of 10, 000 36
Example: Cost-Profit-Volume Analysis Plot of total costs $(000) 800 700 600 500 400 300 200 100 0 D B C A 0 2 4 6 8 10 Annual Output (000) 37 12 14 16

Example: Cost-Profit-Volume Analysis ¨ Range approximations ¨ B Superior (up to 4, 999 units) ¨ C Superior (>5, 000 to 11, 111 units) ¨ A superior (11, 112 units and up) 39
Factor Rating Method 40
Factor Rating Method A general approach to evaluating locations that includes quantitative and qualitative inputs Ø Most widely used location technique Ø Useful for service and industrial locations Ø Rates locations using both Ø Ø tangible (quantitative) factors such as short-run and long-run costs and Ø intangible (qualitative) factors such as education quality, labor skills. 41
Factor Rating Procedure: Ø Determine which factors are relevant Ø Assign a weight to each factor that indicates its relative importance compared with all other factors. Ø Weights typically sum to 1. 00 Ø Decide on a common scale for all factors (such as 1100), and set a minimum acceptable score if necessary Ø Score each location alternative along each factor Ø Multiply the factor weight by the score for each factor, and sum the results for each location alternative Ø Choose the alternative that has the highest composite score, unless it fails to meet the minimum acceptable 42 score
Example: Factor Rating A photo-processing company intends to open a new branch store. The following table contains information on two potential locations. Which is better? Scores (Out of 100) Factor Weight Alt 1 Alt 2 Proximity to existing source . 10 100 60 Traffic volume . 05 80 80 Rental costs . 40 70 90 Size . 10 86 92 Layout . 20 40 70 Operating Cost . 15 80 90 43 1. 00

Centre of Gravity Method 45
Center of Gravity Method Ø A method for locating a distribution center that minimizes distribution costs Ø Finds location of a single distribution center serving several destinations Ø Used primarily for services Ø Treats distribution costs as a linear function of the distance and the quantity shipped Ø The quantity to be shipped to each destination is assumed to be fixed Ø The method necessitates to identify coordinates and weights shipped for each location and includes the use of a map that shows the locations of destinations Ø The map must be accurate and drawn to scale 46 Ø A coordinate system is overlaid on the map to determine relative locations
Center of Gravity Method Considers • Location of existing destinations eg. Markets, retailers etc. • Volume to be shipped • Shipping distances (or costs) • Shipping cost/unit/mile is constant 47
Center of Gravity Method If quantities to be shipped to every location are equal, you can obtain the coordinates of the center of gravity by finding the average of the x-coordinates and the average of the y-coordinates 48
Center of Gravity Method Suppose you are attempting to find the center of gravity for the problem. Destination x y D 1 2 2 D 2 3 5 D 3 5 4 D 4 8 5 18 16 Here, the center of gravity is (4. 5, 4). This is slightly west of D 3 from the Figure 49
Center of Gravity Method When the quantities to be shipped to every location are unequal, you can obtain the coordinates of the center of gravity by finding the weighted average of the x-coordinates and the average of the y-coordinates 50
Grid-Map Coordinates n y xi. Qi 2 (x 2, y 2), Q 2 y 1 n y 3 x 1 i=1 Cx = n Vi i=1 1 (x 1, y 1), Q 1 x 2 yi. Qi i=1 Cy = n Vi i=1 where, 3 (x 3, y 3), Q 3 Cx, Cy =coordinates of the new facility at center of gravity xi, yi =coordinates of existing facility i Vi =annual volume shipped 51 from or to the ith x 3 x location
Center of Gravity Method: Example 1 Suppose the shipments for the problem depicted in Figure are not all equal. Determine the center of gravity based on the following information. Destination x y Weekly Quantity D 1 2 2 800 D 2 3 5 900 D 3 5 4 200 D 4 8 5 100 18 16 52 1, 000
Center of Gravity Method: Example 1 The coordinates for the center of gravity are (3. 05, 3. 7). You may round the x-coordinate down to 3. 0, so the coordinates for the center of gravity are (3. 0, 3. 7). This south of destination D 2 (3, 5). 53

Final Thought The ideal location for many companies in the future will be a floating factory ship that will go from port to port, from country to country – wherever cost per unit is lowest. 60
