Locating a Single Facility
Expand onsite, build another facility, or relocate to another site Onsite expansion Building a new plant or moving to a new retail or office space Comparing several sites Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Selecting a New Facility
Step 1: Identify the important location factors and categorize them as dominant or secondary. Step 2: Consider alternative regions; then narrow to alternative communities and finally specific sites. Step 3: Collect data on the alternatives. Step 4: Analyze the data collected, beginning with the quantitative factors. Step 5: Bring the qualitative factors pertaining to each site into the evaluation. Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.1 A new medical facility, Health-Watch, is to be located in Erie, Pennsylvania. The following table shows the location factors, weights, and scores (1 = poor, 5 = excellent) for one potential site. The weights in this case add up to 100 percent. A weighted score (WS) will be calculated for each site. What is the WS for this site? Location Factor Weight Score Total patient miles per month 25 4 Facility utilization 20 3 Average time per emergency trip Expressway accessibility 15 Land and construction costs 10 1 Employee preferences 5 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.1 Location Factor Weight Score Total patient miles per month 25 4 Facility utilization 20 3 Average time per emergency trip Expressway accessibility 15 Land and construction costs 10 1 Employee preferences 5 The WS for this particular site is calculated by multiplying each factor’s weight by its score and adding the results: WS = (25  4) + (20  3) + (20  3) + (15  4) + (10  1) + (10  5) = = 340 The total WS of 340 can be compared with the total weighted scores for other sites being evaluated.

Applying the Load-Distance (ld) Method
Identify and compare candidate locations Like weighted-distance method Select a location that minimizes the sum of the loads multiplied by the distance the load travels Time may be used instead of distance Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Applying the Load-Distance (ld) Method
Calculating a load-distance score Varies by industry Use the actual distance to calculate ld score Use rectangular or Euclidean distances Different measures for distance Find one acceptable facility location that minimizes the ld score Formula for the ld score ld =  lidi i Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Application 11.2 What is the distance between (20, 10) and (80, 60)? Euclidean distance: dAB = (xA – xB)2 + (yA – yB)2 = (20 – 80)2 + (10 – 60)2 = 78.1 Rectilinear distance: dAB = |xA – xB| + |yA – yB| = |20 – 80| + |10 – 60| = 110 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Application 11.3 Management is investigating which location would be best to position its new plant relative to two suppliers (located in Cleveland and Toledo) and three market areas (represented by Cincinnati, Dayton, and Lima). Management has limited the search for this plant to those five locations. The following information has been collected. Which is best, assuming rectilinear distance?

Using Break-Even Analysis
Compare location alternatives on the basis of quantitative factors expressed in total costs Determine the variable costs and fixed costs for each site Plot total cost lines Identify the approximate ranges for which each location has lowest cost Solve algebraically for break-even points over the relevant ranges Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Variable Costs per Unit
Example 11.3 An operations manager narrowed the search for a new facility location to four communities. The annual fixed costs (land, property taxes, insurance, equipment, and buildings) and the variable costs (labor, materials, transportation, and variable overhead) are as follows: Community Fixed Costs per Year Variable Costs per Unit A $150,000 $62 B $300,000 $38 C $500,000 $24 D $600,000 $30 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.3 Step 1:Plot the total cost curves for all the communities on a single graph. Identify on the graph the approximate range over which each community provides the lowest cost. Step 2:Using break-even analysis, calculate the break-even quantities over the relevant ranges. If the expected demand is 15,000 units per year, what is the best location? Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

(Cost per Unit)(No. of Units)
Example 11.3 To plot a community’s total cost line, let us first compute the total cost for two output levels: Q = 0 and Q = 20,000 units per year. For the Q = 0 level, the total cost is simply the fixed costs. For the Q = 20,000 level, the total cost (fixed plus variable costs) is as follows: Community Fixed Costs Variable Costs (Cost per Unit)(No. of Units) Total Cost (Fixed + Variable) A $150,000 B $300,000 C $500,000 D $600,000 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

(Cost per Unit)(No. of Units)
Example 11.3 To plot a community’s total cost line, let us first compute the total cost for two output levels: Q = 0 and Q = 20,000 units per year. For the Q = 0 level, the total cost is simply the fixed costs. For the Q = 20,000 level, the total cost (fixed plus variable costs) is as follows: Community Fixed Costs Variable Costs (Cost per Unit)(No. of Units) Total Cost (Fixed + Variable) A $150,000 B $300,000 C $500,000 D $600,000 $62(20,000) = $1,240,000 $1,390,000 $38(20,000) = $760,000 $1,060,000 $24(20,000) = $480,000 $980,000 $30(20,000) = $600,000 $1,200,000 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.3 The figure shows the graph of the total cost lines. | | | | | | | | | | | | 1,600 – 1,400 – 1,200 – 1,000 – 800 – 600 – 400 – 200 – – Annual cost (thousands of dollars) Q (thousands of units) A (20, 980) (20, 1,390) (20, 1,200) (20, 1,060) D B A is best for low volumes B for intermediate volumes C for high volumes. We should no longer consider community D, because both its fixed and its variable costs are higher than community C’s. C C best 6.25 14.3 Break-even point B best A best Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.3 The break-even quantity between A and B lies at the end of the first range, where A is best, and the beginning of the second range, where B is best. (A) (B) $150,000 + $62Q = $300,000 + $38Q Q = 6,250 units The break-even quantity between B and C lies at the end of the range over which B is best and the beginning of the final range where C is best. (B) (C) $300,000 + $38Q = $500,000 + $24Q Q = 14,286 units Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.3 The break-even quantity between A and B lies at the end of the first range, where A is best, and the beginning of the second range, where B is best. No other break-even quantities are needed. The break-even point between A and C lies above the shaded area, which does not mark either the start or the end of one of the three relevant ranges. (A) (B) $150,000 + $62Q = $300,000 + $38Q Q = 6,250 units The break-even quantity between B and C lies at the end of the range over which B is best and the beginning of the final range where C is best. (B) (C) $300,000 + $38Q = $500,000 + $24Q Q = 14,286 units Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Hint: In this problem, lease length is analogous to volume.
Application 11.5 By chance, the Atlantic City Community Chest has to close temporarily for general repairs. They are considering four temporary office locations: Property Address Move-in Costs Monthly Rent Boardwalk $400 $50 Marvin Gardens $280 $24 St. Charles Place $360 $10 Baltic Avenue $60 Use the graph on the next slide to determine for what length of lease each location would be favored?

Locating a facility within a Supply Chain Network
When a firm with a network of existing facilities plans a new facility, one of two conditions exists Facilities operate independently Facilities interact Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Locating Within a Network
A five step GIS framework Step 1: Map the data Step 2: Split the area Step 3: Assign a facility location Step 4: Search for alternative sites Step 5: Compute ld scores and check capacity Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

The Transportation Method
A special case of linear programming Represented as a standard table, sometimes called a tableau Rows of the table are linear constraints that impose capacity limitations Columns are linear constraints that require a certain demand level to be met Each cell in the tableau is a decision variable, and a per-unit cost is shown in each cell Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Transportation Method for Location
Basic steps in setting up the initial tableau Create a row for each plant and a column for each warehouse Add a column for plant capacities and a row for warehouse demands Each cell not in the requirements row or capacity column represents a shipping route from a plant to a warehouse. The sum of the shipments in a row must equal the corresponding plant’s capacity and the sum of shipments in a column must equal the corresponding warehouse’s demand Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Plant Warehouse Capacity San Antonio, TX (1) Hot Spring, AR (2) Sioux Falls, SD (3) Phoenix 5.00 6.00 5.40 400 Atlanta 7.00 4.60 6.60 500 Requirements 200 300 900 Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Dummy plants or warehouses The sum of capacities must equal the sum of demands If capacity exceeds requirements we add an extra column (a dummy warehouse) If requirements exceed capacity we add an extra row (a dummy plant) Assign shipping costs to equal the stockout costs of the new cells Finding a solution The goal is to find the least-cost allocation pattern that satisfies all demands and exhausts all capacities Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.4 The optimal solution for the Sunbelt Pool Company, found with POM for Windows, is shown below and displays the data inputs, with the cells showing the unit costs, the bottom row showing the demands, and the last column showing the supply capacities. Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.4 Below shows how the existing network of plants supplies the three warehouses to minimize costs for a total of $4,580. All warehouse demand is satisfied: Warehouse 1 in San Antonio is fully supplied by Phoenix Warehouse 2 in Hot Springs is fully supplied by Atlanta. Warehouse 3 in Sioux Falls receives 200 units from Phoenix and 100 units from Atlanta, satisfying its 300-unit demand. Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

Example 11.4 Below shows the total quantity and cost of each shipment. The total optimal cost reported in the upper-left corner of the previous table is $4,580, or 200($5.00) + 200($5.40) + 400($4.60) + 100($6.60) = $4,580. Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall
