基于机器学习的港口国监督检查选船和检查员排班预测优化模型

2、内容简介

Efficientinspection of ships at ports to ensure their compliance with safety andenvironmental regulations is of vital significance to maritime transportation.Given that maritime authorities often have limited inspection resources, weproposed three two-step approaches that match the inspection resources with theships, aimed at identifying the most deficiencies (non-compliances withregulations) of the ships. The first approach predicts the number ofdeficiencies in each deficiency category for each ship and then develops aninteger optimization model that assigns the inspectors to the ships to beinspected. The second approach predicts the number of deficiencies eachinspector can identify for each ship and then applies an integer optimizationmodel to assign the inspectors to the ships to be inspected. The third approachis a semi-“smart predict then optimize” (semi-SPO) method. It also predicts thenumber of deficiencies each inspector can identify for each ship and uses thesame integer optimization model as the second approach, however, instead ofminimizing the mean squared error as in the second approach, it adopts a lossfunction motivated by the structure of the optimization problem in the secondapproach. Numerical experiments show that the proposed approaches improve thecurrent inspection efficiency by over 4% regarding the total number of detecteddeficiencies. Through comprehensive sensitivity analysis, several managerialinsights are generated and the robustness of the proposed approaches is validated.
