Decision Making Methods in Transportation

Step 7: Checking if the solution is optimal

It has already been concluded in Step 4 that in the case of an optimal solution of a linear maximization problem, variable values result in the largest ‘z’ value of the objective function. Hence, we need to check if the solution is optimal after every newly generated table to see if it is necessary to define a new pivot variable or not. As mentioned above, a solution can be accepted as optimal if the values in the last row are positive or zero. In the case of positive or zero values in the last row, the values of the variables are optimized, no more steps are required. If there still are negative values, the variables are still not optimized, and we need to define a new pivot element, see Step 8.

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.
