![]() The C b column contains the coefficients of the variables that are in the base. The initial tableau of Simplex method consists of all the coefficients of the decision variables of the original problem and the slack, surplus and artificial variables added in second step (in columns, with P 0 as the constant term and P i as the coefficients of the rest of X i variables), and constraints (in rows). Write the initial tableau of Simplex method.In this case, a slack variable (X 3, X 4 and X 5) is introduced in each of the restrictions of ≤ type, to convert them into equalities, resulting the system of linear equations: 2 The inequalities become equations by adding slack, surplus and artificial variables as the following table: Inequality type Otherwise there would be multiplied by "-1" on both sides of the inequality (noting that this operation also affects the type of restriction). Make a change of variables and normalize the sign of the independent terms.Ī change is made to the variable naming, establishing the following correspondences:Īs the independent terms of all restrictions are positive no further action is required.Solve using the Simplex method the following problem: Maximize ![]()
