| Περίληψη: | Decision-making processes involving fixed charges arise in various real-world applications and can often be modeled as mixed-integer nonlinear programs (MINLPs) with semicontinuous variables. Perspective reformulation, a technique leveraging perspective functions, offers tight formulations for such MINLPs. In this article, we address the challenge of solving such reformulations by introducing perspective Benders cuts, a family of generalized Benders optimality cuts, and compare them with the classic generalized Benders cuts and the perspective cuts. We focus on their applications to two fixed-charge nonlinear resource allocation problems: a generalized sensor placement problem and a generalized uncapacitated facility location problem. The original quadratic allocation cost functions in these problems are extended to a class of reducible convex functions. By leveraging the reducible property of nonlinear resource allocation problems, we develop an ad-hoc procedure of solving the reduced quadratic subproblems to efficiently separate perspective Benders cuts. These features contribute to a highly efficient branch-and-Benders-cut approach, as demonstrated through extensive computational experiments on various sets of benchmark instances.
