A Pontis simulation models a recommended bridge program for a network of bridges based on a set of scenario parameters. Scenario parameters include budgets, policies, costs and types of work. The goal of a simulation is to generate project alternatives for each bridge by maximizing benefits within a constrained budget. Preservation, preservation plus improvement, replacement and user-defined projects are the competing alternatives. These are ranked and recommended for programming according to an incremental benefit cost analysis. The results of a network level analysis serve as a good starting point for the project development and programming process.
