Devize is cloud-based Monte Carlo simulation software designed to guide engineers through the entire simulation and optimization process. The Web-based application’s workflow allows users to simulate possible outcomes, and results are presented with straightforward explanations. Recommended next steps are provided, making it easy to understand what adjustments are necessary to improve processes and reduce defects. The software includes parameter optimization to find the optimal settings for input variables, sensitivity analysis to help visualize how variability in the inputs affects the output, distribution identification to recommend a distribution that provides the best fit for data, and simulation comparison to evaluate results side-by-side and demonstrate improvements. The application requires no installation, and results are easily accessible from any desktop or mobile device.
