Picking System Digital Twin: A Lab-Based Case Study

Digital Twins have become a focal point of simulation modeling and analysis in recent years and seems to be gaining momentum. As such, there is a need to more fully integrate practical digital twin modeling and analysis into systems simulation courses. In this paper, we present a lab-based digital twin case study of a pick to light picking system. The digital twin design framework and methodology utilize a simulation model that acts a virtual near real-time representation of a physical picking system. The digital twin can be used to analyze picking system configurations such as alternative picking policies, inventory policies, worker allocation to picking zones, and related decisions.
