Stephen M. Robinsonr the output of the system can be made to follow a preassigned trajectory over a specific interval of time, are now well known (see Hirschorn and the references therein or the recent paper by Grasse ). In these studies, nonlinear systems are either defined by a state-space representation or b

Uncapacitated lot-sizing: The convex hull of solutions,ormulation of this problem leads to a very large duality gap. Here the convex hull of the solutions of the economic lot-sizing model is given. In addition, an alternative formulation as a simple plant location problem is examined, and here too the convex hull of solutions is obtained.

,Node-weighted graphs having the König-Egerváry property,ing λ such that the weight of . is equal to the value of λ; the usual König-Egerváry graphs correspond to .=(1, 1, …, 1)..Several characterizations and two polynomial recognition algorithms for .-KEGs are presented. Algorithm 1 either recognizes (.) as being a .-KEG, or else exhibits an ‘obstruction
