Pragmathic offers a very
pertinent mix of expertise that can be used to customize solutions to your
situation. We can help you optimizing many aspects of your industrial activities
and increasing your plant's profitability and competitiveness.
you need to optimize a product (weight, volume, performance, cost,
temperature rise, ...), improve a unit operation or equipment,
troubleshoot your process or identify variability controlling factors,
our knowledge in fundamental engineering sciences, mathematics and
statistics can deliver
cost-effective high fidelity models and solutions.
In some cases, our
work has led to patents.
If you need to simulate and
optimize something unusual, we can help you!

example: design optimization of a new automatic door operator
Step 1: Using design of experiments, find
design weaknesses vs life span and noise. Factors respectively found:
bearing and chain sizes.
Develop a life span model to meet design specs (100,000 cycles),
minimize components costs and support manufacturing process quality
control. Ex.: model predicted a reject rate of X% at 95% confidence
level with no change on the original components selection.

We design custom experimental programs
using two different approaches as required:
the extensive Montgomery's
Response Surface Methodology, in which the Taguchi methods are a
the Dorian Shainin techniques
especially developped to solve quality problems in manufacturing
statistical analysis |
Many multivariate analysis methods are
available: partial least squares (PLS), principal component analysis and
regression, general linear or non-linear (Marquardt) multiple regression
analysis, and dimensional analysis (an often neglected approach).
We have developped special tools to
handle cases where non-linear effects and variable time lags happen. We
have also developped means to check the level of information losses in
compressed archived data. Go here for more
