We introduce a heuristic method for finding good feasible solutions for multi-product lot sizing problems with general assembly structures, multiple constrained resources, and non-zero setup costs and setup times. We evaluate the performance of this heuristic by comparing its solutions to...

In this paper we address the discrete resource allocation problem in a deterministic flow line. We assume that the processing times are convex and nonincreasing in the amount of resources allocated to the machines. We consider the resource allocation problem for a fixed sequence of jobs for...

This paper proposes a decomposition method to compute a lower bound for unconstrained quadratic zero-one minimization. First, we show that any quadratic function can be expressed as a sum of particular quadratic functions whose minima can be computed by a simple branch and bound algorithm. Then,...
