Abstract 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.

重新设计厂内供应物流：案例研究

摘要 本文讨论了工业装配设施内部物流的重新设计。为此，它提出了一个数学公式来优化组件和零件的流程，以供给生产线的不同工作站。这种组件流从供应商卡车到达的接收码头开始。从卡车上卸下的部件通过适当的装卸设备转移到一个或多个存储区域。最后，当需要时，组件被运输到位于装配线上的需求点。所研究工厂的数学公式产生的数值结果表明，通过更好地将供应商分配到接收码头并将零件分配到存储区域，可以节省近 33% 的总配送时间，
