Redesigning the in-plant supply logistics: A case study

[EN] This paper addresses the redesign of an industrial assembly facility's internal logistics. To this end, it proposes a mathematical formulation that optimizes the components and parts' flow to feed the different workstations of the production lines. This flow of components starts at the reception docks where suppliers' trucks arrive. Components unloaded from trucks are moved to one or several storage areas by means of adequate handling equipment. Finally, components are transported to demand point located along the assembly line when required. Numerical results produced by the mathematical formulation for the studied plant show that savings of almost 33% in the total distribution time might be achieved by a better assignment of suppliers to reception docks and parts to storage areas, and by adequately choosing the capacity of the material handling equipment.The work described in this paper has been partially supported by the project "Hiperheuristico Lenitivo de la Variabilidad del Entorno Industrial en la Programacion de Produccion del Lote Econonimo GVA/2017/008" by the Conselleria de Educacion, Investigacion, Cultura y Deporte of the Generalitat Valenciana within the Program "Proyectos de I+D+I para grupos de investigacion emergentes".
