Abstract: The Lane and Front-end Effectiveness Model (LFEM) is a self-contained PC desktop application that allows an analyst to quantitatively predict the impact of changes to their checkout operations. This application, according to the present invention, includes four simulation models representing the complex interactions between customers, staff, and checkstand resources. Three of these models are detailed lane models and the fourth is a store front-end checkout model. An analyst can use the LFEM to evaluate, in detail, different checkstand configurations and transaction processes and the effect these changes have on overall front-end performance. The purpose of this application is to provide retailers with timely information to reduce the risk and uncertainties of investing in new technologies or design changes by predicting their impact and return before committing resources to their acquisition or implementation.

Abstract: The Post Office Effectiveness Model (POEM) is a self-contained PC desktop application enabling an analyst to quantitatively predict the operational and financial impact of changes to Post office (PO) and Automated Postal Center (APC) operations. This application, according to the present invention, includes a Simulation Analysis Module and a Financial Analysis Module. The Simulation Module consists of two simulation models: APC model and PO model. An analyst can use the PO model to predict the effect of an unlimited number of changes in post office design, customer demand patterns, and counter procedures on post office performance. The Financial Analysis Module allows the user to create a Profit and Loss (P&L) statement showing the cash flows, Net Present Value (NPV), Internal Rate of Return (IRR) for deploying APCs using simulation results or user input values. An analyst can use the POEM to provide a sound and quantified basis for developing a business case for investing in new technologies, i.e.
