Systems and methods are provided for task modeling with models that are adaptive and executable at runtime. In one implementation, a method is provided for executing a task model at runtime. The method may comprise providing a task model comprising a plurality of tasks, executing an application to schedule one or more of the tasks, and monitoring a state of one or more of the tasks. Further, the method may include detecting a change in the state of one or more of the tasks, and updating, during runtime execution, the task model based on the detected change in the state of one or more of the tasks.
