Abstract:This work considers the operation of an IWTS involving waterways, ports and locks. Through simulation and optimization, the optimal sequence of maintenance and repair actions on these locks over a specific planning horizon is determined to maximize the throughput of the IWTS for the same period. The simulation model allows users to modify the cargo that a barge carries and the distribution of each commodity type based on demands. In addition, the number of barges transported by each towboat can be specified by the user before a simulation run. During simulation, the vessels are characterized by a set of variables, such as origin, destination, current location, distance traveled, speed, vessel category, product type, product weight, extreme events encountered, and total delay. As part of outputs of the simulation model, barge movement should be tracked through statistical analyses of these variables.
