This paper addresses the question of determining an optimal mix of gas contracts for a producer supplying the North American gas market. We first propose a ...

This paper proposes a numerical technique, called Turnpike Improvement, for the approximation of the solution of a class of piecewise deterministic control...

This paper deals with a class of stochastic differential games where the mode of play changes according to a stochastic jumpprocess. Between two successive...

The vehicle routing problem (VRP) involves the design of a set of minimum cost routes for a fleet of vehicles which services exactly once a set of customers...

This paper deals with a continuous-time stochastic control model designed for planning production and preventive maintenance in a flexible manufacturing syst...

This paper develops a conceptual framework for flexibility. A definition of flexibility is presented that is general enough to be applicable to all areas o...

Un ensemble d'algorithmes permettant de confectionner les itinéraires et l'horaire des véhicules en vue du transport de personnes handicapées est présenté. ...

In this paper a study of Second and Third Degree Stochastic Dominances for the family of concave and convex utility functions is proposed. This is a modific...

Schedule compression is a major concern in project management. We propose an extension of the classical crashing model to include the managerial practice of...

We investigate the complexity of openshop scheduling problems. A number of variations of the shop with different objective functions have been surveyed. The...

Global optimization problems with a few variables and constraints arise in numerous applications but are seldom solved exactly. Most often only a local opti...

We consider the problem of scheduling jobs on a single machine with generalized due dates. The due dates are given according to the position in which a job ...

The aim of this paper is the characterization and the computation of equilibrium solutions in multistage games represented by networks. More specifically, w...

The transient statistical evolution of a single product manufacturing system under hedging point control policies is characterized via a system of coupled p...

This paper shows how the subtour elimination constraints developed by Miller, Tucker and Zemlin for the traveling salesman problem can be improved and exten...

Consider the optimal control problem for the two processor flow-shop when processing time is a (linear) function of the state. Since the latter also depends...

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

We consider projects represented by a PERT network, with convex cost-of-time functions on individual activities, and we show the existence of an efficient m...

The multiple vehicle many-to-many routing problem is presented in the context of a dial-a-ride system. It is solved by mini-clustering first and optimal ro...

We present an algorithm that solves the problem of finding the vehicle schedule which minimizes total inconveniences for travel along a fixed path, where se...
