During this paper we learn a source restricted undertaking scheduling challenge within which the source utilization of every job may possibly fluctuate through the years proportionally to its various depth. We formalize the matter via a combined integer-linear software, end up that possible answer life is NP-complete within the powerful experience and suggest a branch-and-cut set of rules for locating optimum strategies. To this finish, we offer a whole description of the polytope of possible depth assignments to 2 variable-intensity actions attached by means of a priority constraint besides a quick separation set of rules. A computational evaluate confirms the effectiveness of our approach on a number of benchmark circumstances.
