dc.description.abstract | The bridge project is a national construction infrastructural project. With rapid growth of economy, the infrastructure project is increasing rapidly. The related road and bridge projects are the main construction, and the relevant bridge detection is an important part of the bridge management. In case of bridge collapse, bridge detection should be further studied in terms of maintenance and management responsibilities. How to improve the efficiency of periodic detection of bridges in further consideration of the cost of personnel, machinery and vehicles as well as the planning of the detection area within the detection period has become a significant topic of bridge maintenance.
In this study, for the problem of bridge detection, the optimal mathematical model of expenditure was established by setting constraints to be solved by LINGO 17.0 software according to manpower, vehicles, machinery, construction period and the number of bridges to be detected. When there are differences in the field, the parameters and constraints should be adjusted for the re-calculation in relation to sensitivity analysis of the parameters as well as adjustment of the engineer, supervisor, vehicle rental and dispatching and construction period. For verifying the rationality of this model, assume the detection of bridge in A, B, C, D four work areas as a sample test to find the solution for the lowest cost by optimized mathematical model in comparison with the cost calculated by means of human experience assignment, showing the result for the optimal mode dispatching is lower cost and more efficient than that of human experience dispatching; it can be used as an important decision reference for decision makers in their planning. | en_US |
