Scheduling production and distribution of rapidly perishable materials with hybrid GA's

Abstract

This paper considers the problem of scheduling the production and distribution activities of a network of plants supplying rapidly perishable materials. The main challenges are (1) addressing simultaneously several interrelated scheduling and routing problems, and (2) finding solutions that take into account the amount of cooperation/ interaction necessary between the various plants. We propose a strategy that combines genetic algorithms and fast schedule construction heuristics for job scheduling and truck routing. The effectiveness of the approach is evaluated against other methods used in industrial practice on a challenging large-scale case study. © Springer-Verlag Berlin Heidelberg 2007.
