An Excel spreadsheet version of the Software Development Productivity Model described here that you are free to download and use for your own estimating. I hope it works as well for you as it has for me.
Data Reconciliation

A detailed description of the algorithms and analysis used within the Resolver data reconciliation engine.
Measurement Uncertainty.pdf
The objective of this paper is to arrive at simplified yet realistic uncertainties by making some generally applicable assumptions with regard to the installed conditions of the flow measurement device for typical installations.

Resolver is an Excel add-in that performs data reconciliation using a high performance, accurate, and robust algorithm optimized for the data reconciliation problem. It uses the same problem setup as the Solver Excel-add-in. In fact the problems are interchangeable. You can setup and solve a problem in Resolver and then use the same setup and problem definition to try and solve it with Solver, just in case you want verification of the results!
Resolver is not limited to trivial problems: it has been tested with hundreds of variables, and hundreds of linear, non-linear, and inequality constraints/balances.
Resolver produces all of the global, measurement, and constraint/balance diagnostics that you would expect. With the results presented in Excel, it is easy to use these diagnostics to analyse and locate the underlying problems.
Now Resolver has been updated with improved inequality convergence and sensitivity analysis.
