摘要：
In view of the low efficiency of bridge maintenance decision-making, insufficient maintenance funds and unreasonable fund allocation, a multi-objective decision-making method for bridge deck maintenance scheme of highway was proposed. Firstly, a database was established to collect quantitative data of maintenance methods. Secondly, entropy-weight TOPSIS and analytic hierarchy process (AHP) were used to determine the maintenance priority coefficients of bridge decks in highway networks and the weights of maintenance objectives respectively. Thirdly, a multi-objective decision-making model based on 0-1 knapsack problems was established. Finally, five bridges on Raocheng Highway (G1501) located in Shenyang city in Liaoning Province, China were taken as a case study to demonstrate the validity and the effectiveness of the proposed method. The results showed that the proposed method considers the maintenance priorities of bridge decks during the maintenance decision-making process and can give reasonable and feasible maintenance solutions, thus it can be an effective support for the maintenance decision-making management of highway bridges. © 2020, Editorial Department of Journal of Northeastern University.
