Abstract:
1. A method for task supervision, wherein for a plurality of tasks the following step is performed for each task: scheduling the task for processing; logging the task scheduling by storing a task identifier in a log memory, said task identifier comprising at least one dedicated parameter of the scheduled task, the at least one dedicated parameter being one of a group comprising a task priority, a required processing time, a consumed processing time, a processing deadline, and a task type indicator; identifying the scheduled task with the task identifier assigned to the scheduled task, wherein the task identifiers stored in the log memory form a task history pattern of scheduled tasks; evaluating the task history pattern to determine whether a failure appears in the task-based data processing, wherein evaluating the task history pattern comprises comparing the task history pattern with at least one predefined criterion representing a reference pattern; determining a failure if the task history pattern and the reference pattern match; and taking at least one safety measure if the evaluation indicates a failure.
