The Markov renewal viewpoint of single part manufacturing systems under hedging point control policies, subjected to a constant demand for parts rate, is us...

La programmation linéaire généralisée peut être étendue au cas des programmes mixtes en utilisant seulement l'algorithme primal révisé du simplexe en variab...

Indefinite quadratic programs with quadratic constraints can be reduced to bilinear programs with bilinear constraints by duplication of variables. Such red...

We consider the complexity status of scheduling <i>n</i> jobs in an openshop with <i>m</i> machines, when overlapping of jobs is permitted, for some classic...

A new branch-and-bound algorithm for linear bilevel programming is proposed. Necessary optimality conditions expressed in terms of tightness of the follow...

This paper deals with the implementation of the interior point cutting plane algorithm of Goffin-Haurie-Vial, with a special application to the solution of ...

The interaction between a utility company and electricity cogenerators is modeled via a game theoretic, systems analysis approach, under the assumption of a...

A bounded vertex coloring of a graph <i>G</i> is a usual vertex coloring in which each color is used at most <i>k</i> times (where <i>k</i> is a given numbe...

We present algorithms for computing some distance functions between two (possibly intersecting) polygons, both in the convex and nonconvex cases. The inter...

We present in this paper a linear time algorithm for the computation of some distance functions between convex polygons in R² in the general case...

This paper presents a new heuristic for the Euclidean planar traveling salesman problem. The heuristic takes advantage of the natural alignment of the point...

We consider the problem of determining a hyperplane that separates, as "well" as possible, two finite sets of points in <i>Rⁿ</i>. We analyze two...

A manager planning a distribution network faces a multiple-vehicle routing problem. The first step is to assign customers to vehicles. One way to do this is...

This paper deals with a stochastic programming model which complements long range market simulation models such as those currently developed by several gas ...

The (<b>R</b>,max,+) algebra gives raise, to a "linear algebra" very usefull in the context of DEDS which can be represented by envent graphs. Some propert...

The Airline Crew Scheduling Problem can be defined as the problem of finding a set of feasible rotations so that the total cost is minimum and all the fligh...

In this paper, we report on an updated, improved version of the MARKAL energy model, developed in the late 1970's under the aegis of member countries of the...

The refining industry is faced with medium and long term planning problems (e.g. crude supply, stocks, capacity decisions) where an important part of the da...

In this paper, we present decomposition algorithms for the solution of large scale stochastic dynamic problems, with convergence results and implementation ...

A notion of Nash equilibrium, called event-adapted equilibrium, is defined for non-cooperative, multi-stage games where uncertainty is gradually resolved. ...
