Embodiment Construction

[0099] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0100] see figure 1 , the invention discloses a method for assigning pilots based on an improved discrete brainstorming optimization algorithm, comprising:

[0101] Step 1: Establish a local database and perform data preprocessing; the specific process is as follows:

[0102] (1a) Read in the ship information, and determine the number of pilots M and the level of pilots required for the ship piloting task according to the ship information;

[0103] Among them, pilot levels are divided into 5 levels:

[0104] 1, 2, 3, 4, 5 are specific pilot levels, meaning as follows:

[0105] 1: Senior Pilot

[0106] 2: First Class Pilot

[0107] 3: Secondary Pilot

[0108] 4: Third level pilot

[0109] 5: Level 4 Pilot

[0110] Among them, senior...

Abstract

The invention discloses a pilot assignment method based on an improved discrete brainstorm optimization algorithm. The pilot assignment method comprises the following steps: determining problem constraint conditions according to problem description, and establishing a pilot assignment model; and solving the pilot assignment model based on an improved discrete brain storm optimization algorithm, and finding out an optimal pilot assignment plan. According to the discrete brainstorm optimization algorithm, a method for learning from individuals to two random individuals in the same class of the brainstorm optimization algorithm is provided, and an implementation method for individual fusion and random interference addition in discretization of the brainstorm optimization algorithm is provided. By adopting the improved discrete brainstorm optimization algorithm, the search efficiency of the optimal path can be improved, the algorithm is prevented from falling into local optimum, and the precision of the algorithm is improved.

Description

technical field [0001] The invention belongs to the technical field of ship piloting, and in particular relates to a method for assigning pilots based on an improved discrete brainstorming optimization algorithm. Background technique [0002] With the rapid development of my country's economy and the increasing globalization and integration of the world economy, ports are becoming more important as the main channel for cargo transportation between countries. my country is a big port country, and the rapid development of the port industry has brought opportunities and challenges to China's major ports. In order to improve the competitiveness of the port, optimize the allocation of resources, and improve the informationization of pilotage is imperative. [0003] Pilot resources are one of the core resources of ports and play a vital role in the process of piloting ships. In the process of assigning pilots, we usually have to consider whether the level of the pilot matches th...
