Abstract

ABSTRACT This paper first summarises a survey of logistics and production planning engineers in the automotive industry on the use of simulation models to solve planning tasks in logistics and production conducted by the authors. As a solution for the analysed trade-off between a required quick provision of simulation results and a tolerable inaccuracy of the simulation results, the authors describe and evaluate the application of mesoscopic discrete-rate-based simulation models for two typical production and logistics planning tasks in the automotive industry. In terms of level of detail, mesoscopic simulation models fall between object-based discrete-event simulation models and flow-based continuous simulation models. Mesoscopic models mainly represent logistics flow processes on an aggregated level through piecewise-constant flow rates by applying the discrete-rate simulation paradigm instead of modelling individual flow objects. This leads to fast model building and computation.
基于介观离散率的生产与物流规划仿真模型
本文首先总结了作者对汽车行业物流和生产计划工程师使用仿真模型解决物流和生产计划任务的调查。为了解决所需的快速提供仿真结果和可容忍的仿真结果不准确性之间的权衡,作者描述并评估了基于介观离散率的仿真模型在汽车工业中两个典型的生产和物流规划任务中的应用。细观仿真模型在细节程度上介于基于对象的离散事件仿真模型和基于流的连续仿真模型之间。介观模型主要是采用离散率模拟范式,通过分段恒定的流量在一个聚合水平上表示物流过程,而不是对单个流动对象进行建模。这导致了快速的模型构建和计算。
