Business process modeling and digital twins: a literature review

Business process modeling is one of the most important steps in managing the lifecycle of a business process. Business process simulation using process simulation tools is a technique used to produce estimates of business process performance and cost structure. A digital twin of a business process is a virtual model used to replicate the behaviour of a real business process. The difference between a digital twin and a business process simulation is that the simulation does not require real-time data, while the digital twin relies on real-time data. This paper is about digital twins of business processes. The achievements of existing research in the field of business process simulation and digital twins are presented. In addition, the limitations of the existing research are investigated.
