The Open Group Architecture Framework (TOGAF) business architecture is a benchmark for data architecture, application architecture and technical architecture, and occupies a guiding role in the design of enterprise system architecture. However, due to the limitation of its description form, the dynamic characteristics of the business architecture cannot be analyzed. A colored petri net (CPN) executable model generation method based on ROAD business architecture was proposed. The method was based on the four types of models proposed by the division of the ACF metamodel of TOGAF business architecture-rule model (RM), organization model (OM), activity model (AM) and data model (DM). The corresponding relations between the different description forms of the four types of models and the CPN modeling language was established. The five-stage modeling method of executable models with RM, OM, AM and DM as the main body was then proposed. Finally, the feasibility of the method was verified by taking the business architecture of the kindergarten intelligent morning inspection robot system as an example. It achieves creation of CPN executable model and breaks the limitations of modeling languages of business architecture and CPN model.
