G/G/1 models for a single machine under different types of interruptions

Queueing theory is commonly used to evaluate the performance of manufacturing systems. Due to the complex nature of interruptions in practice, existing models cannot provide reliable estimates of the performance. This paper proposes a systematic way to classify different types of interruptions seen in a single machine system and suggests proper queueing models for each category. The G/G/1 approximate models are derived based on the insight from comparing different interruption types.
