Although CFD/DFD is one of the most used diagrams in the Hatley‐Pirbhai (H/P) modeling method, H/P does not offer the semantics to support the execution capability of behavioral modeling. In the cyber‐physical systems that operate in an open environment, an executable model is necessary to perform simulation for early phase validation. This study proposes a method for providing the execution capability by improving H/P using SysML with the MBSE Object‐Oriented context. SysML is supported by the fUML execution engine that has been standardized by the Object Management Group (OMG). With this standardized platform, the simulation results are more precise, consistent, and less ambiguous, which are necessary to perform better validation. The results showed that SysML diagrams maintained model readability and could easily implement the H/P method compared to the H/P diagrams. With the SysML model simulation, systems engineers could perform a functional analysis on the feature control logic in the early stages of the system development.
