Abstract
The present research Project proposal aims to solve the Multi-Level Lot Sizing Problem (MLLSP) using heuristics and metaheuristics. The heuristics propose are Relax-and-Fix and Fix-and-Optimize. The metaheuristics propose are Tabu Search and Genetic Algorithm. These methods are embedded with mathematical programming to solve the problem. Therefore, a mathematical reformulation to the MLLSP model is also presented aiming to integrate the exact resolution of the model with the heuristics and metaheuristics. The results obtained are compared with those reached by the exact solution of the original model of the MLLSP and with the recent results reported by the literature. There are some preliminaries results already found using a multi-population genetic algorithm embedded with resolution of the reformulated model. These results were recently accepted as full paper in the 2011 IEEE Congress on Evolutionary Computing. (AU)
