Demurrage pattern analysis using logical analysis of data: A case study of the Ulsan Port Authority

作者：

Highlights：

• We apply the logical analysis of data (LAD) techniques to study demurrage at port.

• Real data of operations of vessels at the port of Ulsan are used for LAD analysis.

• We extract data patterns of vessels with demurrage and without demurrage using LAD.

• Data patterns obtained by LAD well predict the demurrage rate at the port of Ulsan.

• LAD results are further analyzed to suggest policies reducing the demurrage rate.
