Konzeptentwicklung zur Steuerung nicht-wertschöpfender Logistikkosten in einer Primär-Aluminium-Gießerei durch die Kopplung linearer Optimierung und Simulation

Abstract

The aim of this study is to quantify and reduce the non-value added logistical costs in the aluminium industry’s supply chain. This study attempts to simulate the internal supply chain of a primary aluminium casthouse and identify the wastes by implementing a lean thinking approach. After highlighting the possible improvements, optimization models attempt to reduce these wastes which create non-value added costs to the system. This concept is further developed by interfacing the simulation model with the optimization model to validate the improvements. The success of the concept is tested by measuring the reduction in redundant logistical costs of a case study founded on the real casthouse specifications. Scenarios are defined to analyze the casthouse supply chain under different perspectives. The potential gain of the new concept is verified by applying it to these scenarios. In conclusion, the results analysis of the scenarios indicates the success of the main objective of this study; to develop a new concept that controls the non-value added logistical costs in the primary aluminium casthouse supply chain.
