Technique for evaluating location choices in economic terms Steps: Determine the fixed and variable costs for each alternative Plot the total-cost lines for all alternatives on the same graph Determine the location that will have the lowest total cost (or highest profit) for the expected level of output - Assumptions: Fixed costs are constant for the range of probable output Variable costs are linear for the range of probable output The required level of output can be closely estimated Only one product is involved

question

What is Factor Rating? What is the procedure?

answer

General approach to evaluating locations that includes quantitative and qualitative inputs Procedure: Determine which factors are relevant Assign a weight to each factor that indicates its relative importance compared with all other factors. Weights typically sum to 1.00 Decide on a common scale for all factors, and set a minimum acceptable score if necessary Score each location alternative Multiply the factor weight by the score for each factor, and sum the results for each location alternative Choose the alternative that has the highest composite score, unless it fails to meet the minimum acceptable score

question

What is the Center of Gravity Method? What is the equation for finding the X and Y coordinates?

answer

Method for locating a distribution center that minimizes distribution costs Treats distribution costs as a linear function of the distance and the quantity shipped The quantity to be shipped to each destination is assumed to be fixed The method includes the use of a map that shows the locations of destinations The map must be accurate and drawn to scale A coordinate system is overlaid on the map to determine relative locations - X= Sum of x values/number of destinations Y= Sum of y values/number of destinations

question

What if the shipments to each destination are not equal in the Center of Gravity Method?

answer

Each X and Y value must be weighted according to the quanity, then divided by the total quantity instead of the number of destinations. i.e. X Y Weekly Quantity 2 2 800 3 5 900 Total: 1,700 X=[(2x800)+(3x900)]/1,700 Y=[(2x800)+(5x900)]/1,700

question

answer

applications: Location decisions Compare location alternatives in terms of their impact cost on the total distribution costs for the system Involves working through a separate model for each location being considered - Production planning Capacity planning Transshipment - assumptions The items to be shipped are homogeneous Shipping cost per unit is the same regardless of the number of units shipped There is only one route or mode of transportation being used between each origin and destination - Information requirements A list of the origins and each one's capacity or supply quantity per period A list of the destinations and each one's demand per period The unit cost of shipping items from each origin to each destination
