Modelling dynamic bottlenecks in production networks

Abstract

Bottlenecks, as the key ingredients for improving the performances of the production networks, have been profoundly studied. However, the major definitions of bottlenecks are derived in terms of the throughput and based on the theory of constraints (TOC). Moreover, before the specific measures can be applied on them, it is not straightforward to localise dynamic bottlenecks due to their complex dynamic characteristics. Distinguishing from the traditional view at the bottlenecks, this article therefore develops a systematic and comprehensive definition of dynamic bottlenecks of the production networks based on both the TOC and the bottleneck-oriented logistic analysis. Afterwards, the defined dynamic bottlenecks are modelled by means of discrete simulation using practical data, aiming at visualising them in the production network. By applying the logistic operating curves, the practical application of the proposed research and its procedures is discussed as well.
