Resolver Production Data Reconciliation

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 constraints, both linear and nonlinear.

Overview

Resolver came about as a result of trying to use Solver to solve process data reconciliation problems, as reported in Is Excel Solver suitable for Production Data Reconciliation?. As noted, Excel has a lot of advantages for setting up process data reconciliation problems, and is widely used for operational and production accounting. Along with some advantages, some issues were revealed which have been overcome with Resolver.Resolver uses a reconciliation model defined via constraint equations expressed as Excel cell formula in the same way as Solver.

The data reconciliation problem is defined in a very similar way to Excel Solver. In fact the model definitions are interchangeable, although Resolver can only solve for the Gaussian objective function, and Solver cannot produce the reconciliation diagnostics.

Resolving will write the results back into the variable cells, and also produces a report to help diagnose the reconciliation problems. This produces the well established gross, constraint, and measurement error diagnostics.

 

 

Testimonials

“Peter is a visionary within the systems domain and an ardent and indefatigable enthusiast of applied technologies. Peter not only manages to maintain currency across the multitude of breakneck-paced technology trends, but can shape these into a working paradigm that enables an organization to formulate and deliver solutions, services and a coherent marketing strategy. Certainly Peter's insight into optimization, production and operational systems (typified by MES functions) has enabled him to realize tangible benefits whether applied to externally to clients, or internally within his own organization. Personally Peter has provided me tools to attain a new level of enthusiasm and clarity for this domain and was as a source of professional inspiration. It was a pleasure working with and learning from Peter. I would certainly recommend Peter to any organization looking for a kick start or step change in their approach to the delivery, application or management of technology.”
