As an example of Arena's basic ROI Calculator functionality, we have provided the VICS (Voluntary Inter-Industry Commerce Standards) Association with a N-Tier benefits calculator. This calculator determines the potential benefit to an organization of a CPFR (Collaborative Planning, Forecasting and Replenishment) trading partner relationship. Seperate calculations exist for suppliers, manufacturers upstream, manufacturers downstream, and distributors. The user should download the model, enable the macros and then scale the model for their own unique financials and adoption curve.
