A Heuristic Based Solution to the Roadway Maintenance and Rehabilitation Planning Problem

摘要

This article presents a heuristic based procedure to solve the roadway maintenance andrehabilitation planning problem formulated as a discrete-state discrete-time Markov decisionprocess. The procedure derives the optimal maintenance and rehabilitation frequency andmagnitude by minimizing the equivalent uniform annual cost in a forward manner constrained byknown optimality properties. Not only does the procedure reduce the solution space and hencethe overall computational cost, but is capable of evaluating the reliability of roadway facilitiesthrough the stochastic state progression defined by the Markov process.
