In this paper, decision-making tree and Markov process are used to select maintenance strategies of in-service bridges with the minimum LCC (life-cycle cost). Other costs in life cycle are considered comprehensively when establish the model to find the optimal maintenance strategy. Finally, an example is given to verify the efficiency of the model. The research methodology can provide effective support to bridge maintenance management decision-maker for making management strategies.

Minimum Expected Cost

The goal of bridge management is to determine and implement the best possible strategy that ensures an adequate level of safety at the lowest possible life-cycle cost. Although this is generally recognized, the integration of life-cycle cost analysis with bridge reliability analysis has been very limited. Moreover, this has been formulated and illustrated only for individual bridges. A framework for optimal network-level bridge maintenance planning based on minimum expected cost is presented. The goal is the minimization of the expected maintenance cost of a bridge stock with maintenance of the lifetime reliability of each bridge above an acceptable (target) level. The approach is illustrated for a stock of realistic highway bridges. Individual bridges in this stock have different ages, and their reliabilities are time dependent. The framework offers a rational basis for optimizing the resource allocation for management of a stock of gradually deteriorating bridges based on balancing life-cycle maintenance cost and lifetime reliability. This has important practical implications in the development of the optimal management strategy for the bridge stock.

Maintenance Model

In this paper the problems of traditional operation maintenance strategy is introduced. Uncertain multi-stage and multi-objective decision-making model of operation and maintenance is shown in this paper. Considering the life cycle cost, the best maintenance scheme is determined through the establishment of an uncertain multi-stage and multi-objective decision-making model of operation and maintenance. It also proves the practical applications of UMM model by GIS example.
