Title

Multi-objective search with evolving fitness functions for solving scheduling problems

Abstract

This talk will present some of the development in multi-objective approaches for solving complex scheduling problem. The first part of the talk will investigate multi-objective and weighted single objective approaches to a real world workforce scheduling problem. The computational experiments show that multi-objective genetic algorithms can create solutions whose fitness is close to that of the solution created by the genetic algorithms using weighted sum objectives even though the multi-objective approaches know nothing of the weights. In second part of the talk will discuss the variable fitness function approach to enhance the metaheuristic approaches by evolving weights for each of the multiple objectives. The results show that the variable fitness function approach improves the performance of constructive and variable neighbourhood search approaches on workforce scheduling problem instances.
