Given a set of logical sentences together with probabilities that these sentences are true, the probabilistic satisfiability (PSAT) problem consists, in it...

A count of Kekulé structures for all 1812 distinct fullerene isomers of C₆₀ shows that 20 isomers surpass the count of 12500 for icosahedral C<su...

This paper presents methods to determine the optimal transfer batch sizes of various part types between two machines so as to minimize the sum of the total ...

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 ...
