This paper describes an integrated infrastructure system (with emphasis on pavement and bridge management systems) that allows cost minimization or benefit maximization. It integrates separate infrastructure systems so that management may optimally allocate scarce resources across the combined systems. Fuzzy set theory is used in these optimizations to better address the desirability or undesirability of the condition states used to categorize the infrastructure segments modeled. Both steady-state and multi-year models are part of this system. The full mathematical structure of the simpler steady-state problem is presented, and sample multi-year output showing the integrated budgets is given.
