QMSys GUM vs. BrandMap® 10

The QMSys GUM Software is specifically developed to evaluate the uncertainty associated with physical measurements, chemical analyses, and calibration procedures. It offers three unique methods to calculate measurement uncertainty. The first method, GUF Method for linear models, is focused on linear and quasi-linear structures, adhering to the GUM Uncertainty Framework. This method calculates partial derivatives that represent the initial terms of a Taylor series, which helps in determining sensitivity coefficients for the equivalent linear model, and subsequently uses the Gaussian error propagation law to find the combined standard uncertainty. The second method, GUF Method for nonlinear models, is tailored for nonlinear scenarios where the outcomes show a symmetric distribution, using various numerical strategies such as nonlinear sensitivity analysis and higher-order sensitivity indices, along with quasi-Monte Carlo simulations that apply Sobol sequences. By incorporating these diverse methodologies, the software equips users with extensive tools for performing thorough uncertainty analysis in various measurement situations, ensuring robustness and precision in their results. Additionally, it enhances decision-making processes by providing clear insights into the levels of uncertainty involved.

Researchers globally opt for this software due to its intuitive interface that facilitates rapid analysis and the creation of visually appealing biplots, correspondence maps, and MCA layouts. This 64-bit application is compatible with both MAC and PC platforms. The Brand Projector I functionally displays and computes essential characteristics for brand repositioning on a visual map. Meanwhile, Brand Projector II offers an interactive experience where researchers can adjust attributes and observe how the brand dynamically shifts in relation to the changes made. This combination of features makes the program an invaluable tool for those in the research community.
