DTAS3D uses the Monte Carlo principle to model products based on their tolerances and assembly relationships, then performs simulation calculations to determine whether the product design meets its key dimension requirements. It also predicts the product’s qualification rate and conducts root cause analysis. The results mainly consist of the following categories. 1. 1. Routine statistical parameters: such as maximum value, minimum value, mean, standard deviation, pass rate, kurtosis, skewness, etc. 2.2. Various parameters for fitting distributions: The type of distribution to be fitted; the software supports normal distribution, uniform distribution, gamma distribution, beta distribution, and other types. Various estimates under the fitted distribution, such as upper and lower quantiles, estimates of the upper and lower tolerance rates, etc. 3.3. Confidence intervals for various statistical parameters, etc. The true value of statistical parameters is difficult to obtain, such as the true value of the mean. But we can estimate the probability that the true value falls within a certain interval; this probability is commonly referred to as the confidence level, and this interval is known as the confidence interval. 4. 4. Transfer coefficients and contribution degrees, etc. The transfer coefficient represents the geometric influence factor, and is essentially an approximation of the derivative of a function at a certain point. Contribution degree is a comprehensive evaluation index that takes into account both the transfer coefficient and the tolerance value; for specific methods, reference can be made to calculation approaches for contribution degree such as the extreme value method and probability method. Based on these results, plan optimization and the like can be carried out. “Forward with determination, and innovate with courage! DTAS thanks every customer for their support.
