A Column Generation Based Hyper-Heuristic to the Bus Driver Scheduling Problem

The Bus-Driver Scheduling Problem

We present new metaheuristics for solving real crew scheduling problems in a public transportation bus company. Since the crews of these companies are drivers, we will designate the problem by the bus-driver scheduling problem. Crew scheduling problems are well known and several mathematical programming based techniques have been proposed to solve them, in particular using the set-covering form...

Solving a Large Real-world Bus Driver Scheduling Problem with a Multi-assignment based Heuristic Algorithm

The bus driver scheduling problem (BDSP) under study consists in finding a set of duties that covers the bus schedule from a Brazilian public transportation bus company with the objective of minimizing the total cost. A deterministic 2-phase heuristic algorithm is proposed using multiple assignment problems that arise from a model based on a weighted multipartite graph. In the first phase, the ...

A Heuristic Approach to Column Generation for Airline Crew Scheduling

Airline crew scheduling gives rise to many diicult and interesting optimisation problems. With straightforward approaches to the crew pairing problem one speciically needs to solve very large set-covering problems. One suggested approach to these problems is column generation. In column generation, the choice of master solver can have a signiicant impact on performance, both with respect to spe...

Column Generation Based Heuristic for the Generalized Assignment Problem

This paper proposes a column generation based heuristic suitable for large and hard instances of the generalized assignment problem. First, just to be able to obtain the convergence of the column generation is reasonable times, it uses a sophisticated “triple” dual stabilization, combining piecewise linear penalty functions, Wentges’ dual smoothing and sub-gradient directional smoothing. In ord...
