Weight Engineering - Statistical Studies %X Over the past 15 or so years, Mass Properties analysis techniques have used the same basic philosophy for calculations. The prediction of mass through a program life cycle can be calculated by adding contingency to a basic mass calculation. As the program matures, this contingency decreases until the program is completed. The contingency schedule is based on a statistical analysis of historical data gathered from the satellite industry. The mass growth tends to follow a standard bell curve. By applying the mean of historical mass growth, statistically there is a 50% chance being under the allocation. The single prediction does not provide insight into the uncertainty of that value. A simple method using the distribution of the historical mass growth to provide a prediction would offer that insight. This prediction, applied at the part level, is presented in statistical terms, easily understood by anyone with a technical background. %B 64th Annual Conference, Annapolis, Maryland %I Society of Allied Weight Engineers, Inc. %C Annapolis, Maryland %P 26 %8 5/14/05 %G eng %U https://www.sawe.org/papers/3379/buy %9 21.0.
