VORSIM - A Model Building Framework for Microsoft Excel
Entry ID: USDA0430
Abstract: "VORSIM - A Model Building Framework for Microsoft Excel" is a computer program
which helps the user build and simulate mathematical models in the Microsoft
Excel spreadsheet. VORSIM can be used to build time series models with tags,
static partial equilibrium economic models, engineering process models, or
business plan models for sensitivity analysis of key assumptions. VORSIM is
especially ... useful for the construction of large spreadsheet models with groups
of standardized equation structions. Since models and associated files created
by VORSIM reside in spreadsheets, all of the capabilities of Excel are
available for model building. Successful VORSIM modeling requires spreadsheet
skills and knowledge about mathematical models.
