Analysis of internal logistic systems based on event logs

Internal logistic systems are an important part of the modern industry. Their design is challenging due to high complexity and heterogeneity. It involves as a rule elaborate simulations, but the analysis of the simulation results is often limited to acquisition of key indicators. In addition, analysis of these systems at runtime is difficult due to a large amount of monitoring data. Nonetheless, in-depth analysis of logistic systems during their design and operation would contribute much to improving their performance. This paper describes a generic approach for analysis of internal behavior of logistic systems based on event logs. The purpose of the analysis is the identification of design and operation problems and their causes. The approach is demonstrated for simulation analysis of baggage handling systems.
