Decision Making Methods in Transportation

Step 5: Defining the pivot variable

We use the pivot variable to determine the variable that has to be the unit value, and it is also a key parameter in the transformation of the unit value. Firstly, we have to look at the last row of the table. Since the solution is not optimal, we have to choose the smallest negative value in the last row. The pivot variable is chosen from this column. To define the adequate element, we need to define a new indicator column (as in Table 2) by dividing the beta values of the table by the values in the same row of the column including the pivot variable. The pivot variable is chosen from the intersection of the row with the smallest non-negative indicator and the column with the smallest negative value in the last row.

The content of the book fits to the teaching program of the subject titled ‘Decision making methods’ taught at Budapest University of Technology and Economics (BME) Faculty of Transportation Engineering and Vehicle Engineering. The book firstly introduces the most frequently applied general approaches of solving linear optimisation problems and then discusses a few special decision support models. In the course of the investigation the book discusses the models from theory to practice, especially considering transportation related problems and models. The introduced models can efficiently support transportation related decision making processes. Therefore, it can fructify for its readers in the field of transportation management, transportation process coordination and transportation system operation.
