This paper presents a new approach for planning the dispatching, conflict-free routing, and scheduling of automated guided vehicles in a flexible manufactur...

Crew-Opt is a set-covering method that uses column-generation to produce nearly optimal solutions to crew scheduling problems. We presented this method at t...

We consider the problem of finding a shortest path for a car-like robot (approximated by a point) maneuvering around obstacles. This robot is capable of for...

This survey paper describes the significant advances made in time constrained vehicle routing and crew scheduling problems. In terms of solution methodolog...

This paper examines whether there is a substantial additional payoff to be derived from using mathematical optimization techniques to globally define a set ...

This paper describes strip sequencing models for large scale traveling salesman problems arising in flexible manufacturing operations in two or three discre...

In this paper we explore a new branching strategy for branch-and-bound approaches based on column generation for the vehicle routing problems with time wind...

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...
