News - Greycon Finds New Version of Xpress-MP is 35%
Faster
Greycon and Dash Optimization
today announce that the recently released 2004 version of Dash’s
market leading Xpress-MP optimization software is at least 35% faster
on a range of industrial problems.
Established in the late 1980s, Greycon is a leading
provider of software solutions in Supply Chain Optimisation, Production
Planning, Finite Capacity Scheduling and Trim Optimization. Greycon
is entirely dedicated to developing innovative software for the
manufacturing industry. Its corporate aim is to help our customers
develop and maintain their competitive advantage by improving management
systems and overall performance, through state-of-the-art software
products.
Greycon and Dash have been working together for
many years. The combination of Greycon’s exceptional domain
knowledge and mathematical modeling and optimization skills, and
Dash’s Xpress-MP software and support has resulted in Greycon
becoming a market leader in areas such as Supply Chain Planning,
Trim Optimization and Forecasting.
The 2004 version of Xpress-MP is the result of
a significant R&D effort over the last 12 months. Many new features
have been added which makes the solution of Mixed-Integer Linear
Programming (MIP) faster and more efficient. These include algorithmic
improvements (such as better branching and estimation) and software
engineering (such as more efficient execution and memory management).
Greycon’s problems are very challenging and Dash is very pleased
to see that this speed improvement carries over to the most difficult
of problems.
Dash is committed to year on year improvements
in performance and has consistently achieved increases in speed
as determined by the aggregate performance over a wide range of
academic and industrial benchmark problems. When taken with improvements
in hardware, the last ten years has seen speed improvements of over
3,000 times. To put this into context, a problem that used to take
4 months now takes one hour.
Dr. Constantine Goulimis, Greycon Managing Director,
said, “We are delighted with the performance improvements in
Xpress-MP 2004. We have a comprehensive internal benchmark consisting
of over 400 problems, and we were astonished to see that the time
taken dropped by more than 35%. Since this includes overheads and
computations outside Xpress-MP, it means that improvement in Xpress-MP
was even greater than the 35% reduction we observed. In turn, this
will enable us to deliver products to our customers that are even
more effective. Problems get bigger all the time and customer’s
expectations increase year by year; optimizer performance is an
important part of remaining competitive”. Alan Dormer, Director
of Dash Optimization adds, “We have invested a lot in Xpress-MP
2004 in terms of development, testing and benchmarking and we are
very pleased with the end product. We are confident that many more
of our customers will share Greycon’s recent experience”.
