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.

The .xlsx and .xls file types are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine. The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. The most common software used to open .csv files are Microsoft Excel and RecordEditor, (for more information on .csv files and software, please visit https://www.file-extensions.org/csv-file-extension).
