BRIDGE MAINTENANCE LEVEL OF SERVICE OPTIMIZATION. FINAL REPORT

The development of a methodology and computer based decision assistance tool to aid in the formulation of strategy for routine and preventive maintenance of highway bridges is presented. The resulting analysis method and computer program are titled MAINTBRG. The methodology utilizes a level of service approach to optimize maintenance strategy of bridge elements under given budget constraints. The optimal strategy is selected by maximizing a value function relating to the levels of service. The maintenance levels of service represent degrees of maintenance effort for each bridge element considered in the analysis. MAINTBRG is a specialized and extended version of the Algorithm for the Selection of Optimum Policy (ASOP). The analysis utilizes a nonlinear integer programming algorithm coded in Fortran-77. A supplementary methodology and computer program was developed to assist in the determination of input data required in the MAINTBRG analysis. The RESNEEDS (Resource Needs) program uses system wide bridge element volume, condition, maintenance needs, and other data to provide a summary assessment of system wide bridge element conditions and resource requirements to achieve each alternate level of service for the bridge elements.
