The Simplex Algorithm developed by Dantzig (1963) is used to solve linear programming problems. This technique can be used to solve problems in two or higher dimensions. Calculate Gallons Per Minute. Get a one gallon container, and time how long it takes to fill it with water. For the best accuracy measure the flow 3 or 4 times and average the times together. The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM).

For linear multiple-objective problems, a necessary and sufficient condition for a point to be efficient is employed in the development of a revised simplex algorithm for the enumeration of the set of efficient extreme points. Five options within this algorithm were tested on a variety of problems. Results of these tests provide indications for effective use of the algorithm.

Overview of the simplex method The simplex method is the most common way to solve large LP problems. Simplex is a mathematical term. In one dimension, a simplex is a line segment connecting two points. In two dimen-sions, a simplex is a triangle formed by joining the points. A three-dimensional simplex is a four-sided pyramid having four corners.

If we would have inequalities instead of , then the usual simplex would work nicely. The two-phase method is more tedious. But since all coe cients in z = 2x 1 + 3x 2 + 4x 3 + 5x 4 are non-negative, we are ne for the dual simplex. Multiply the equations by 1 and add to each of the equations its own variable. Then we get the following tableau. x ...
