I studied
Mathematics and Economics
("Wirtschaftsmathemtik") at the University
of Augsburg. I graduated in January 1992. My master's thesis was
about MCF,
which is
a implementation of the primal and dual network simplex algorithm. MCF is available free of charge for
academic use. A specialized version of MCF,
called 181.mcf,
is a member of the SPEC CPU2000 benchmark suite.
A revised version, called
429.mcf, has become a
member of the current CPU2006 benchmark suite.
SPEC's mission is to establish, maintain, and endorse a standardized
set of relevant benchmarks and metrics for performance evaluation of
modern computer systems.
Since January 1992, I am a member of the research department Optimization at ZIB. In November 1997, I received my
Ph.D. (Dr. rer. nat.) entitled Optimal
Vehicle Scheduling in Public Transit at the Technische University of Berlin.
At ZIB, I have worked on several scientific and industrial projects on
vehicle
and crew scheduling in public transit and on some academic software
projects.
In July 2000, my colleague Dr.
Ralf Borndörfer and I started a civil law partnership. Since
March 2004, Dr. Steffen Weider has
become our third companion in our partnership
Dres. Löbel, Borndörfer & Weider
GbR. We are three freelancer aiming at the transfer of our mathematical
optimization knowhow to the transportation industry. Our main focus is currently
on (sequential and integrated) vehicle and duty scheduling in public
transit. The corresponding
mathematical planning software tools VS-OPT©, DS-OPT©, RS-OPT©, and IS-OPT© are
exclusively
distributed by the IVU Traffic
Technologies AG in their planning system MICROBUS. |
