Model-based logistic controlling of converging material flows

Order elements are often not punctually or synchronically provided in supply chain processes involving the convergence of different material flows (e.g., assemblies). This paper focuses on the development of a model for reviewing the timeliness and simultaneousness of these converging material flows. The model is validated by simulation studies as well as several practice based case studies. The application of this mathematical model allows the influence of critical supply processes on the logistic performance of the supply chain to be identified and quantified. Hence, measures to improve the logistic performance can be derived and their anticipated impact can be visualized. (C) 2013 CIRP.
