In this paper we analyze the efficiency of a given robot movement schedule for the case of a flowshop robotic production cell with <i>m</i> different machin...

It is well known that several combinatorial optimization problems can be nicely and readily modeled as an appropriate quadratic 0-1 function to be optimized...

In the Dual Bin Packing Problem (DBP), there are an unlimited number of bins of identical capacity, and unsplittable items of given weights. The aim is to ...

This paper propose a column generation method for optimally solving the rostering problem. Various strategies for accelerating the column generation process...

We consider the problem of defining a fair sharing of the total advantages gained by two regions (players) which decide to coordinate their environmental po...

The purpose of this paper is to formulate and solve an optimization problem arising in the operations of a numerical control machine such as a punch press. ...

In operations planning in an open pit mine an economic blocks model is generally used which attempts to determine which blocks will be extracted during each...

Given a binary matrix <i>E</i>, the Seriation Problem consists of determining a permutation of the rows of <i>E</i> minimizing the sum over all columns of t...

The majority of the examination timetabling software programs available today suffer from one of the following drawbacks: either the techniques are not very...

We consider a price setting duopoly producing differentiated goods, where the players can learn by doing and from each other. The unit production cost is mo...

We consider the problem of finding a shortest path for a car-like robot maneuvering in a convex cell. This robot, capable of forward and backward motion, is...

We study the problem of finding a shortest path for a car-like mobile robot with a minimal turning radius constraint. This vehicle can move either forward o...

This paper deals with the modeling of economy-environment interactions for several countries which are assumed to behave competitively for the control of th...

The stochastic linear programming problem with recourse has a dual block angular structure. It can thus be handled by Benders decomposition or by Kelley's m...

This paper presents the development of a new optimal dynamic programming algorithm for the minimization of the total traveling cost for the traveling salesm...

We give a new formulation to the multiple-depot vehicle scheduling problem as a set partitioning problem with side constraints, whose continuous relaxation ...

The NP-hard problem addressed in this paper is well known in the scheduling literature as <i>R</i>|<i>C</i>_{<font size=-1>max</font>}. We introduce...

The problem of finding a minimal length trajectory (MLT) for a mobile robot has changed in the last five years, as vehicle kinematics have come to be taken ...

We present a method for designing spine layouts. A spine layout is a layout in which a main aisle is used for the movements between the work cells located o...

In this paper, optimal strip strategies are developed for a variety of two-dimensional and three-dimensional sequencing problems arising in flexible manufac...
