OSORIO GOMEZ, Juan Carlos; CASTRILLON MONTENEGRO, Oscar Eduardo; TORO CARDONA, Juliana Andrea  and  OREJUELA CABRERA, Juan Pablo. Hierarchical production planning model in flexible job shop including a preemption and sequence-dependent setup times. Ing. Investig. [online]. 2008, vol.28, n.2, pp.72-79. ISSN 0120-5609.

Production planning and control are complex problems for manufacturing organisations. Hierarchical production planning and control is one way to address the problem as it can reduce its complexity and reach good solutions in reasonable computational time. This paper presents a hierarchical approach to resolving production programming in a flexible job shop configuration; this problem includes preemption and sequence-dependent setup times. Although non-optimal (as expected), good solutions were obtained as shown in the validation of the method.

Keywords : hierarchical planning; production programming; preemption; sequence-dependent setup time; parallel machines.
