"A Harmony Search Approach for A Dynamic Cell Formation Problem" Laura Y. Escobar-Rodríguez, Edwin A. Garavito-Hernandez and Leonardo H. Talero-Sarmiento This document addresses a harmony search approach for a dynamic cell formation problem presented as a mixed-integer linear model aiming to minimize the total costs associated with the production process. The mathematical model takes into account changing demand and part mix, machine relocation and machine sequence.
