Schedule execution in autonomic manufacturing execution systems

This paper discusses a manufacturing execution system (MES) that prefers and attempts to follow a given schedule. The MES performs this task in an autonomic manner, filling in missing details, providing alternatives for unfeasible assignments, handling auxiliary tasks, and so on. The paper presents the research challenge, depicts the MES design, and gives experimental results. The research contribution resides in the novel architecture in which the MES cooperates with schedulers without inheriting the limitations of the world model employed by the scheduler. The research forms a first development, and a list of further research is given.
