Frequently Asked Questions
Operations research (OR) is the planning and decision support, based on mathematical models and algorithms.
OR in Aachen merges modern mathematical optimization; design, analysis, and implementation of algorithms from computer science; and practical applications from science, technology, industry and services.
We have a list of open topics which is accesible from within the RWTH network only.
Admission to the Master's program in business adminstration requires a fundamental knowledge in operations research and may need to be demonstrated via a "Kenntnisstandprüfung". This means passing the written examination ("Klausur") about the material of our Bachelor's course "quantitative methods" which is offered every summer term. Contact our office for obtaining access to the "Lernraum" which contains lecture notes, exercises, and homework assignments.
The bachelor's course "quantitative methods" is currently tought exclusively in German. All our master's courses are held in German or English, upon request.
That depends! We have an expertise in planning and decision problems from production, logistics, traffic and transport, education and health care; but we are open to surprises. Check our "industry" pages and contact us if you think that we may be a good fit.
We do not have a particular "PhD program." Typically, working towards a PhD goes with a paid position as a research/teaching associate. Such a position may imply teaching duties or administrative tasks assigned to you. That is, being a PhD "student" usually means that you are "studying" next to your regular "working day." A simple consequence is that we need to have such a position available.
A remark is in order. We receive a lot requests about PhD positions. Please read the above first. If you did not find an open position in our team, please note: we delete (and do not answer) any request that does not personally address one of our team members. We ignore any request that does not specifically refer to our team, and why you would like to work with exactly us (and not any other team in the world). We ignore any request that does not precisely specify a research question you would like to work on with us ("I read your paper about..." is not sufficient!).
Some students need recommendation letters for being accepted to a foundation, for a stipend, or admission to a foreign program of studies. We generally support such requests.
It is easy to truly recommend a person if he/she is known to us, e.g. because they have been teaching/research assistant in our group or because of having completed a thesis with us. Often enough, we "know" students only from a huge lecture. In such a case we refer exclusively to the relative success in the final exam and occasionally to additional material provided to us (e.g., an overview of grades). A personal meeting can increase the "personal touch" we may add to a recommendation letter. If you need a recommendation letter, contact us early (!!) and prepare well so that we can stress your most positive attributes in a truthful manner.
We receive a lot of applications for internships. Please note that we delete emails immediately when they are obviously "broadcasted" to several addressees. If you are seriously interested in an internship with our group, then specify precisely what research project you would like to pursue, and why with us. We cannot fund internships in general, so you should indicate how your stay would be financed.
