Optimizing highway maintenance operations: dynamic considerations
نویسندگان
چکیده
Effective highway maintenance depends on several activities, including the understanding of current and the prediction of future pavement conditions and deciding how to best allocate limited resources for maintenance operations. In this paper, a dynamic micro-level simulation model of highway deterioration and renewal processes is presented. This model is calibrated with data from eight road sections in Virginia and is coupled with an optimization module that optimizes maintenance operations. The analysis offers alternative priority setting schemes that improves current maintenance practices at the project and network levels. This approach provides a blueprint for designing optimal highway maintenance practices. Copyright © 2010 John Wiley & Sons, Ltd. Sys. Dyn. Rev. 26, 216–238 (2010).

Measuring dynamic efficiency of highway maintenance operations ¬リニ
In this paper we discuss a dynamic efficiency measurement model for evaluating the performance of highway maintenance policies where the inter-temporal dependencies between consumption of inputs (i.e., maintenance budget) and realization of outputs (i.e., improvement in road condition) are explicitly captured. We build on a micro representation of pavement deterioration and renewal processes an...

متن کاملScheduling Traffic Signal Maintenance
A major responsibility of highway engineers is to provide for the public a highway system capable of accommodating vehicle and pedestrian travel in a safe, efficient, and economic manner. In developing this highway system, the engineer is responsible for the planning, design, construction, operation, and maintenance of that system. In many instances the maintenance function is relegated to a mi...

To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...
