Research on tugboat scheduling optimization model considering the reliability of tugboat matching scheme [PDF]

Scientific Reports
The selection and scheduling of tugboat matching schemes are key tasks in tugboat assistance operation management. With large ships requiring more tugboat assistance, a two-stage multi-criteria decision-making method is proposed.
