Operations Research Using Excel A Case Study Approach

The geometrical operation of moving from a basic feasible solution to an adjacent basic feasible solution is implemented as a pivot operation. First, a nonzero pivot element is selected in a nonbasic column. The row containing this element is multiplied by its reciprocal to change this element to 1, and then multiples of the row are added to the other rows to change the other entries in the column to 0. The result is that, if the pivot element is in a row r, then the column be… WebbChapter 0: Introduction to Operations Research. Chapter 1: Linear Programming and Simplex Method.
