Diagram a. Block diagram approach - minimize - use when quantitative data is available Example 1. A company needs to locate three departments (X, Y, and Z) in the three areas (I, II, and III) of a new facility. They want to minimize interdepartmental transportation costs, which are expected to be $.50 per load per meter moved. An analyst has prepared the following distances and flow matrices: Distances (meters) Flow’s (loads / week) From /To I II III From /To X Y Z I - 10 20 X - 60 90 II - 10 Y 40 - 160 III - Z 110 140 - a) What is the distance from area III to area I in this new facility? What is the total flow (loads per week) between departments Y and Z? b) If departments X, Y, and Z were to be located in areas I, II, and III, respectively, what would be the total distance (in meters) loads moved each week? c) The optimal solution can be found by a computer program.
