PHPSimplex is an online tool for solving linear programming problems. Usage is free. To access it just click on the icon on the left, or «PHPSimplex» in the top menu.
PHPSimplex is able to solve problems using the Simplex method, Two-Phase method, and Graphical method, and has no limitations on the number of decision variables nor on constraints in the problems.
This tool is designed to help students in their learning as it not only shows the final results but also the intermediate operations. It also offers direct solution for professional use. Other advantages are that it does not require any language to state the problem, offers a friendly interface, it is closer to the user, easy and intuitive, it is not necessary to install anything to use, and is available in several languages (if you want PHPSimplex that is in your language, please contact us).
A user's guide is also available to quickly learn to use the PHPSimplex tool.
Theory of used methods, special cases to consider, examples of problems solved step by step, a comparison between the Simplex method and Graphical method, history of Operations Research and so on will be also found in this website.
