This document discusses Mikrosam's use of constrained multi-optimization and high performance computing (HPC) to improve the design of composites for high pressure vessels. Mikrosam worked with HPC providers to develop an adaptive algorithm that can optimize multiple objectives and constraints in parallel, accelerating the design process by 30%. This reduced material and labor costs by 10-20% and improved Mikrosam's branding. Moving forward, Mikrosam plans to replicate this work for other complex calculations and combine the optimization software with other composite property tools.

5. PROBLEM AND SOLUTION
I4MS 2016: FOSTERING DIGITAL INDUSTRIAL INNOVATION IN EUROPE · 23rd and 24th of June – Amsterdam
Adaptive algorithm for different objective functions and constraints;
Accelerate the determination of design characteristics and decreasing the
overall design time;
Mathematical model for designing a composite for high pressure vessels,
that can be adopted on other forms.
Constrained multi-optimization algorithm for composite design:

6. HPC, supercomputing, the cloud-way of doing things, self-service, etc.,
were not the paradigms used in MIKROSAM;
Reduction of the usual time to design a composite for about 30%
One initial guess for the final optimized material properties;
Replicability of experiments, easier designing (no more “technical”
but rather scientific solution), low CAPEX thinking.
HOW I4MS HELPED
Improvements in the industrial process:

7. Decrease the design and testing costs by 10%
Using base of materials in order to obtain best
combination for the test.
Decrease the labor cost by 20%
Using the HPC for performing complex computations
and multi-objective optimization.

8. HPC, supercomputing, the cloud-way of doing things, self-service, etc., were not
the paradigms used in MIKROSAM;
Change/shift in mentality – use of self-service model to solve our everyday
problems;
The “cloud-way” of thinking, even in HPC related problems;
Clear business results:
Lower labor costs ~ 20%
Lower material costs ~ 10%
Better product design
Improved branding of the company – 10% to 20% depending on the
previous experience.
