Design of Experiments, DoE

training number: Reliability_S04

Target group:

Engineers, technicians, specialists and executives from the areas of development, testing, construction, research and production quality assurance.

About the topic:

Today’s development processes are characterized by complex products and manufacturing processes, as well as by ever more demanding time and cost targets. Design of Experiments (DoE) represents a major building block to meet this pressure to improve efficiency in the field of experimental design. Central applications are attempts to understand complex technologies and processes and, at the same time, to improve or optimize them. In practice, it is still the cases that, despite the existing knowledge about possible methods, “traditional” but mostly inefficient techniques like “One factor at a time” experiments are extensively applied in industrial practice. Negative examples also contribute to this, where the most “basic knowledge” is that DoE was useless, because no significant effects could be found. It is not enough to know only the methodology for a successful use of DoE in practice. The necessary conditions, which must be in place parallel to the actual experiment design, must also be considered. Successful DoE programmes use 80% of the time on planning and securing the experimental conditions especially with regard to variance reduction, and only 20% on statistical analysis. This seminar provides both the methodological foundations of the design of experiments as well as the overall understanding of the planning and evaluation of statistically planned experiments.

Training fee:

On request, we will gladly make you a personal offer.

Training content:

Introduction
Confidence intervals
Full factorial plans
Fractional factorial experimental designs
System optimization – response surface plans
DoE practice – key success factors

Exercises

Each theoretical step important to the understanding of Design of Experiments is demonstrated in a practical exercise with the participants. Independent “process improvements” and “system optimizations” are carried out using real examples. All practical exercises include the necessary success factors.

Prerequisites:

There are no prerequisites for this topic. No prior knowledge of reliability engineering is required.

Software requirements:

Each participant must have a laptop with the following software: Microsoft Excel, Adobe Reader and Minitab (from Version R15). A demo version of the software Minitab can be downloaded from www.minitab.com.

Certification:

The training will end in all cases with a certificate of participation.

Coaching:

Should you so wish, we can put together a time and content tailored coaching concept for you after completion of the training.
