What is modularity in design?
As mentioned earlier, modular design (or modularity) is an approach used to design various products or applications – by breaking it down into separate or independent parts. ... A creative leader chooses modular designs for their products because of its many benefits.
What is modularity in architecture?
Modular design or “modularity in design” is a design approach that subdivides a system into smaller parts called modules or skids that can be independently created and then used in different systems. ... Modular design combines the advantages of standardization with those of customization.
What do you mean by robust design?
„Robust Design is a technique that reduces variation in a product by reducing the sensitivity of the design of the product to sources of variation rather than by controlling their sources. “ „The end result is a robust design, a design that has minimum sensitivity to variations in uncontrollable factors.
What are the two basic stages of Taguchi design?
The design to attain one goal is not usually consistent with the one to attain the other goal. To meet the two goals, Taguchi developed a two-step optimization strategy. The first step is to reduce the variation, and the second step is to adjust the mean on the target.
What is robust design example?
Examples of robust design include umbrella fabric that will not deteriorate when exposed to varying environments (external variation), food products that have long shelf lives (internal variation), and replacement parts that will fit properly (unit-to-unit variation).
What is Taguchi Robust Design?
Taguchi robust design is used to find the appropriate control factor levels in a design or a process to make the system less sensitive to variations in uncontrollable noise factors (i.e., to make the system robust). Ideally, a product's performance should be consistent no matter what the noise values are.
Why Taguchi method is used?
Taguchi method is robust design techniques widely used in industries as it can improve the processing quality, reduce the number of experiments, minimize the processing variation and maintenance and promote the quality stability.
When a product is robust it is?
For most authors robustness is the ability to deal with disturbances without lacking functional requirements , . Taguchi et al.  claim that even deviances in between tolerance ranges can harm the final performance and small deviations of a target value are to be considered as a 'quality loss'.
What's the main purpose of Taguchi methods?
Taguchi Method is a process/product optimization method that is based on 8-steps of planning, conducting and evaluating results of matrix experiments to determine the best levels of control factors. The primary goal is to keep the variance in the output very low even in the presence of noise inputs.
Who defined Taguchi methods?
Genichi Taguchi, a Japanese engineer and statistician, began formulating the Taguchi method while developing a telephone-switching system for Electrical Communication Laboratory, a Japanese company, in the 1950s. Using statistics, he aimed to improve the quality of manufactured goods.
How do you analyze Taguchi design?
Example of Analyze Taguchi Design (Static)

- Choose Stat > DOE > Taguchi > Analyze Taguchi Design.
- In Response data are in, enter Driver and Iron.
- Click Analysis.
- Under Fit linear model for, check Signal to Noise ratios and Means. ...
- Click Terms.
What is S N ratio in Taguchi method?
S/N ratio is the most significant and useful parameter in taking into account of target and variation in comparing two sets of samples, when compared comparing the mean alone. Taguchi method of DoE, uses S/N ratio in ANNOVA calculations.
How do you calculate SN ratio?
So, for complex calculations, you divide the value of the desired signal by the amount of the noise and then take the common logarithm of the result, i.e., log (S ÷ N). After this, if the signal strength measurements are in watts (power), you will then multiply by 20.
How do you calculate Sn in Taguchi?
Higher values of the signal-to-noise ratio (S/N) identify control factor settings that minimize the effects of the noise factors. Taguchi experiments often use a 2-step optimization process. In step 1 use the signal-to-noise ratio to identify those control factors that reduce variability.
What is Taguchi method with an example?
Also, the Taguchi method allows for the analysis of many different parameters without a prohibitively high amount of experimentation. For example, a process with 8 variables, each with 3 states, would require 6561 (38) experiments to test all variables.
What is the difference between full factorial design and fractional factorial design?
Generally, a fractional factorial design looks like a full factorial design for fewer factors, with extra factor columns added (but no extra rows). Using fractional factorial design makes experiments cheaper and faster to run, but can also obfuscate interactions between factors.
How does design of experiments work?
Design of experiments (DOE) is a systematic method to determine the relationship between factors affecting a process and the output of that process. In other words, it is used to find cause-and-effect relationships. This information is needed to manage process inputs in order to optimize the output.
What is orthogonal array in Taguchi method?
Taguchi Orthogonal Array (OA) design is a type of general fractional factorial design. It is a highly fractional orthogonal design that is based on a design matrix proposed by Dr. Taguchi Orthogonal arrays are balanced to ensure that all levels of all factors are considered equally. ...
What is orthogonal design in experiment?
Orthogonal design is an experimental design used to test the comparative effectiveness of multiple intervention components—referred to here as “inter- ventions”—each of which takes on two or more variants.
How do you test an orthogonal array?
How to do Orthogonal Array Testing: Examples
- Identify the independent variable for the scenario.
- Find the smallest array with the number of runs.
- Map the factors to the array.
- Choose the values for any "leftover" levels.
What is Taguchi method PDF?
ABSTRACT: Taguchi Method is a powerful statistical approach to enhance the Quality & Productivity of Process. by optimization of Process Parameters (Nutek Report on Basic Design of Experiment). The Objective. of this study is to implement the Design of Experiments (DOE) based Taguchi Method in Corrugation.
What will be the correct sequence of DOE to understand the process settings?
What are the steps of DOE?
- Set objectives.
- Select process variables.
- Select an experimental design.
- Execute the design.
- Check that the data are consistent with the experimental assumptions.
- Analyze and interpret the results.
- Use/present the results (may lead to further runs or DOE's).
What is the ultimate goal of Six Sigma approach to the product quality?
The main goal of any Six Sigma implementation is quality improvement. The term originally comes from the sigma rating used to statistically rate manufacturing processes in engineering. A six sigma process occurs when no defects are expected in of all chances to produce them.
