Outline of Final Research Achievements

We research on preventive start-time optimization (PSO). PSO determines a suitable set of link weights in an open shortest path network at the network operation start time that can handle any link failure scenario preventively.
PSO minimizes the worst-case congestion ratio in case of failure. PSO can avoid both unexpected network congestion and network instability. We formulate the original PSO problem as a mixed integer liner programming problem by extending the start- time optimization model and describe heuristic approaches.
We also introduce mathematical programming models for the PSO variations. In addition, we expand PSO into generalized preventive start-time optimization (GPSO) to find a link weight set that balances both congestion ratios under no failure and the worst-case failure.
