Implementing big m method
Witryna4 cze 2024 · As you said, the big-M is used to model the non-linear constraint. K[m][i] = p[i] * x[m][i] in case x is a binary variable. The assumption is that M is an upper bound on K[m][i] and that K[m][i] is a non-negative variable, i.e. 0 <= K[m][i] <= M. Also p is assumed to be non-negative. Since x[m][i] is binary, we can have two cases in a … Witryna26 lip 2024 · Table At iteration 3. Relative profits = 0, 0, 0, -1 Since all relative profits are less than or equal to 0. So optimality is reached. This will be the final simplex table and the optimal one. Value of Z at optimality = 6*1 + 2*1 = 8 Following cases can occur while performing this algorithm.
