Upgrading of Degradable Transportation Network by Investment Prioritization in Resource Allocation

Amir Golroo and Afshin Shariat Mohaymany

This study aims to adequately assign the limited available resources to appropriate degraded network components in order to enhance the network reliability. Allocating resources to degraded components would increase the level of performance of components and consequently improve the whole network reliability. Since the performance of the components/network and occurrence of disaster are scholastic, the probabilistic approach is applied to address components/network performance using suitable probability distribution functions. The risk analysis technique needs to be employed to investigate the impacts of investment/upgrading on the network reliability. On the other hand, because the budget is restricted, the best scenario of resource allocation should be chosen to optimally increase the reliability of the entire network utilizing an appropriate optimization method. This study proposes concurrent incorporation of simulation techniques and the dynamic programming method to execute the risk analysis and tackle the optimization problem in order to effectively and efficiently prioritize the limited resources among deteriorated components leading to a more reliable network. A hypothetical case study demonstrates the capability of this methodology.
