Process modeling and simulation (M the nesting and composition relationships (Y-Facet) between components; and a novel, formalized inter-component collaboration protocol (Z-Facet) termed the Entity Flow-Control Flow-Processing Logic (ECPR) strategy. This methodology is engineered explicitly for transparency and extensibility, bridging the gap between the usability of commercial tools and the flexibility of open formalisms. We present its implementation within the open X-Language/XLAB framework, and validate it through three comprehensive case studies: a vehicle CAN bus/ABS system, a computational graph executor, and a custom component extension. Results demonstrate not only functional equivalence with commercial tools (Simulink, AnyLogic), but also, through a comparative architectural analysis and a usability pilot study, showcase superior extensibility and a manageable learning curve. This work provides a reference architecture for open, component-based simulation, enabling both intuitive graphical modeling and researcher-accessible simulation kernel extension.
