WebJan 8, 2024 · It is numerically safer to use a (small) data-dependent value for M. For your case, rewrite as: C [i] [k] + TaskTime [j] [k] - C [j] [k] <= M [i] [j] [k] * (1 - X [i] [j]); You want to choose M i, j, k to be a (small) upper bound on the left hand side when X i, j = 0. A good choice is M i, j, k = U i, k + T j, k − L j, k, WebWelcome to the IBM Community, an place to combine, share known, & support one another in everyday trouble.
