IDT MDH THESIS

However, there remains several challenges to be addressed, such as, expressiveness, to represent the real-time and causality behaviour, and analyzability, to support verification of functional and timing behaviour during early-phases of system development.

On the network layer, routing protocols play an important role in both communication reliability and latency. These two operating systems represent two extremes, where Linux is more focused towards soft real-time systems and seL4 towards pure hard real-time safety-critical systems. This thesis addresses the problems mentioned above and aims to provide reliable and deadline-constrained communication via IWSANs for industrial automation systems.

These two operating systems represent two extremes, where Linux is more focused towards soft real-time systems and seL4 towards pure hard real-time safety-critical systems.

October 17, – Semi-independent subsystems share not only the general resources, but also other logical resources that can only be accessed in a mutually exclusive way, i.

An alternative method is to use Forward Error Correction FEC schemes to provide reliable communication by recovering erroneous data and avoiding unnecessary retransmissions. Bachelor and Odt Theses Important information The complete website is currently down and we are working on to relaunch it as soon as possible. February 10, – For industrial automation, missing the process or control deadline is intolerable, which may terminate industrial application and finally mfh in economic loss and safety problems.

January 21, Status and planning report submission date: Hence, this work elaborates on how to adapt and extend the operating-system task-scheduler to support hierarchical scheduling. The usability aspect is especially important for Linux systems since kernel updates occur much more frequently compared to any other operating system. October 25, – January 13, – Additionally the report must be submitted by the deadline latest.

Finally, the research contributions are validated using representative examples of RTES as well as an industrial case study. Next, we have provided a real-time semantic basis, in order to support expressiveness and verification for structural and behavioural models. January 12, – June 07, Re-examination period 1: March 22, – February 2, Re-examination period 1: We have focused on various operating systems that were lacking the feature of hierarchical scheduling.

We have also contributed with a novel approach to verify thesix schedulers, and a code generator called TAtoC Timed Automata to C which contributes to the effective run-time performance of synthesized timed-automata models.

Scheduler synthesis is related to implementation and design strategies when adding support for hierarchical scheduling in an operating system.

TBD Re-examination period 2: Measurements were conducted in a real industrial environment to verify the thwsis of the proposed solution. An inappropriate scheduling scheme may introduce high transmission jitter and degrade the quality of control.

September 11, – September 4, – On the network layer, routing protocols play an important role in both communication reliability and latency. Hierarchical scheduling has been shown to be a useful tool in counteracting the verification challenges that comes from the growing complexity in software. May 27, – On network layer, routing protocol plays an important role in both communi- cation reliability and latency.
