Error propagation analysis - very important but widely ignored issue,

The ArcAd tool performs more than just tedious calculations. We have implemented a parameter of tolerances to our service, which has an effect on final results within the analysis. Many other procedures do not take into account room for error, which can distort final values. A lack of understanding of basic error analysis has led some very bright scientists and engineers to make some incredible blunders. ArcAd's short circuit online calculator features input data analysis and hard coded error propagation rules ensuring that the results are not more precise than justified by the accuracy of input data.

Typical commercial software has more interfaces and graphic content, which make them more appealing and expensive. ArcAd's on-line tool is user friendly, performs error propagation analysis - very important but widely ignored issue, and is offered at a reasonable price. We strongly believe that if a resulting margin of error can't be quantified, then it's not engineering, but only a guess. As far as we are aware, none of the available competing products performs proper error analysis. It wouldn't be a problem if most accurate system equipment data were available. Experience shows that by far most real world studies are built upon approximate and therefore more or less accurate input data. The concept of precision is very important indeed and can impact results in surprising ways.

  1. Well said, an unknown error cant be compensated for.
