                     2.4.2  Minisum Location Model
                            The objective of minisum location model is to minimize the sum of the weight
                     distances between the new facility and the other existing facilities.The minisum location

                     problem is formulated as below:


                                              Formula 2.5 : Minisum location model


                     Where f(x) = total cost of travel between new facility and existing facility
                            wi   = the weighted score
                            x     = x-coordinate for new facility
                            y     = y-coordinate for new facility

                            ai    = x-coordinate for existing facility
                            bi    = y-coordinate for existing facility
