Life-Cycle Maintenance Management for Bridge Networks under Reliability Considerations
With Xiaofei Hu, (PhD student)
The research addresses the problem of optimizing maintenance, rehabilitation and replacement (MR&R) decisions for deteriorating bridges in highway networks. Incorporating network topology increases the complexity of the maintenance optimization problem; the traditional MDP framework suffers from the curse of dimensionality. In the literature, numerical methods were implemented to solve bridge management problems in networks of small sizes.
In the first part of the research, we search for the optimal maintenance plan which ensures an adequate level of network reliability at the lowest possible life-cycle maintenance cost. We show that the network reliability function can be obtained directly from the minimal cut sets under reasonable approximations. Analytical and efficient approaches are developed for both decomposable and non-decomposable networks, and the framework is extended to networks with multiple origin-destination pairs. In the second part, we investigate large scale networks with the objective of minimizing the disruption to traffic caused by bridge failures. The critical step is to decompose the network-level problem into single facility problems. We theoretically prove the validity of this decomposition using a grid network model.
Decision support system for joint design, and strategic maintenance and rehabilitation planning for highway systems under multiple constraints
With Jinwoo Lee (PhD student)
The subject of this research is the joint optimization of pavement design and MR&R strategies for system-wide pavement infrastructure. We are currently focusing on the optimization of the structural number in design and the MR&R plan with multiple treatments such as maintenance and resurfacing for a single pavement to minimize its total life cycle costs, using a combination of analytical and numerical tools. We reduce the number of decision variables in mathematical programming by using calculus of variations and numerical methods. The next step will be to extend this method to a system of highway pavements under capital investment and maintenance constraints. The research results should be of use for developing countries in the process of expanding their highway networks in the face of multiple constraints.
Pavement Resurfacing Policy for Minimization of Lifecycle Costs and Greenhouse Gas Emissions: Network Level Analysis
With Darren Reger (PhD student) and Arpad Horvath
Traditionally, pavement management optimization has focused on minimizing user and agency costs. Previous research has expanded beyond minimization of life-cycle costs, to also include GHG emission, by solving the multi-criteria optimization problem with two objectives. Case studies were performed for an arterial and a major highway to highlight the contrast between policy decisions for various pavement and vehicle technologies. The current research aims to extend the multi-objective optimization methodology (with life-cycle costs and GHG emissions) to the management of an entire highway network in the presence of realistic constraints.

Han Cheng
Han Cheng is a Ph.D. student in the Department of Civil and Environmental Engineering. His research interest lies in transportation infrastructure management and network optimization considering multi-objectives from economic and environmental perspectives. He currently is working on analyzing the tradeoffs between life-cycle costs and greenhouse gas emissions in hierarchical urban transit systems with heterogeneous traffic demand. Prior to pursuing the Ph.D. degree, Han received his Master’s degree in Civil and Environmental Engineering from the University of California, Berkeley in 2014, and his two Bachelor’s degrees in Civil Engineering and Economics from Tsinghua University in 2013.

Jinwoo’s current research topics involve joint optimization of construction and multiple treatments (i.e., reconstruction, maintenance and resurfacing) for system-wide pavement management in continuous time, evaluation of the effectiveness of road safety countermeasures, and comparison of the performance of different high collision concentration location detection methods. Prior to pursuing his Ph.D. degree at Berkeley, Jinwoo received his B.S. in Civil and Environmental Engineering from the Korean Advanced Institute of Science & Technology (KAIST) in 2010. He received awards at the International Astronomy Olympiad (IAO) and Mathematical Olympiads in Korea.
Allan Ogwang
I am a PhD student in Civil and Environmental Engineering. My research interests are in pavement materials, especially concrete used in rigid pavements. The research incorporates environmental sustainability goals by utilizing life cycle assessment tools to determine the best options for pavement materials. I will assess the maintenance, rehabilitation, and reconstruction actions in light of pavement durability. I received an M.S in Civil Engineering at the University of California, Berkeley in 2013; and a B.S in Civil and Transportation Engineering at the University of Dar-es-Salaam, Tanzania in 2011.
