Abstract

The invention discloses a pilot assignment method and device based on an improved intelligent water drop algorithm, and relates to the field of ship pilot assignment, and the method sequentially comprises the following steps: determining problem constraint conditions according to problem description, and building a pilot assignment model; solving the pilot assignment model based on an improved intelligent water drop algorithm, and finding out an optimal pilot assignment plan. Aiming at the defects that an intelligent water drop algorithm is insufficient in heuristic property and is easy to fall into local optimum, the invention provides a selection strategy based on an optimal candidate node subgroup, and the search efficiency and the algorithm precision are improved. And an improved intelligent water drop algorithm is adopted to solve the pilot assignment model, so that the precision of a solving result is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of ship pilot dispatching, and in particular relates to a method for assigning ship pilots. Background technique [0002] With the rapid development of our country's economy, the world economy is increasingly globalized and integrated, and the port, as the main channel of cargo transportation between countries, is more important. With the help of the inherent advantages of port cities, shipping logistics has become the engine of economic development of coastal port cities. The quality of pilotage represents the degree of opening to the outside world and market competitiveness of ports to a certain extent. At the same time, pilotage dispatching capabilities also determine the effect of pilotage services and the image of ports. [0003] Pilot resources are one of the core resources of ports, and the problem of pilot assignment is an NP-hard combinatorial optimization problem, which is very suitable for solving...
