| Brief Description of Research Project | The following objectives are established for this project: (i) Considering the multi-objective problem in the context of lifecycle management of transportation infrastructure with pre-assigned weights for the individual objectives (such as LLCC, risk, safety, resilience, etc.), reflecting the priorpreferences of the decision-maker for obtaining the optimal I&M policies using DRL; (ii) augmenting the state space with weights of the objectives to parametrize the optimal I&M policies, assisting in evaluating decisions and prioritization of different goals; (iii) estimating the Pareto front on high dimensional manifolds through DRL architecture modifications, providing the unique, truly multi-objective solutions; (iv) validating developed approaches based on existing networks and in-use practices. In general, this project will hence establish an I&M planning framework for multi-objective settings, considerably advancing currently available tools for infrastructure asset management, offering significant cost savings and promoting better safety and other objectives. The established methodology may therefore advise DOTs on how to use modern DRL approaches in order to attain optimal I&M policies, prioritize various asset management goals/objectives, and investigate potential benefits. |
