Planning and implementation of road BMPs on a watershed scale can be a difficult task because of the need to prioritize locations while accounting for multiple constraints, such as the available budget, continuous maintenance, and equipment scheduling. Using simulated annealing (SA) as its heuristic optimizer, BMP-SA accounts for sediment being...

American railroads have faced a declining share of freight
traffic relative to other modes. Although a variety of reasons have been
identified for this decline, most experts agree that a contributing problem
is that the rail system is overdeveloped with unprofitable branchlines.
Many economic models have been utilized to analyze...
