Heuristics in inventory control: operational empirical evidence

José Álvaro Assis Lopes, José Manuel Loução de Matos

Resumo


This paper intends to be a methodological contribution to the comparison of results obtained inventory management through formal modeling and those implemented through simulation and optimization processes, particularly using genetic algorithms (evolutionary). The development focuses primarily on backorder situation for models of reorder point, periodic review and (S, s, R) where the demand per unit time and lead time are normal distributions. The analyses are realized for a set of heuristics applied to the management of a durable fast moving item. The main limitations in modeling and optimization of numerical nature are refereed.

 

Keywords

Heuristics, Simulation, Optimization, Evolutionary algorithms, Reorder point policy, Periodic review policy, (S, s, R) policy.
