Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] According to the system formed by this method, the system includes two parts:

[0020] 1. The software system completes the setting and negotiation operation of the initial parameters of the negotiation. The software system is formed to use the Agent software to model the ship; refer to the multi-Agent heuristic negotiation model to establish a two-ship negotiation collision avoidance model, which is represented by a set. Such as figure 1 Shown: A represents the set of negotiators, which generally consists of a give-way boat and a direct boat, or consists of two give-way boats. X represents a set of negotiation topics, and the negotiation topics mainly refer to the collision avoidance scheme that the negotiators intend to adopt. R repre...

Abstract

The invention discloses a decision-making method for ship collision avoidance based on digital negotiation. The method comprises Step 1: establishing an automatic negotiation software system; Step 2: inputting the parameter value of the preference model of a negotiator; Step 3: determining the role of the negotiation; Step 4: determining a negotiation proposal; and Step 5: carrying out the negotiation. The method solves the problem that: the existing automatic collision avoidance decision-making system can not coordinate and give an economical total collision avoidance proposal in the situation that two ships encounter difficulty, thereby being capable of causing two ships that encounter difficulty to obtain coordination and a more economical total collision avoidance proposal by the digital negotiation, reducing the collision avoiding cost of the ships and improving the operation safety and transporting efficiency of the ships.

Description

technical field [0001] The invention relates to a method for ship collision avoidance decision-making, in particular to a method based on digital negotiation, which can provide a coordinated and economical overall collision avoidance scheme. Background technique [0002] The current intelligent decision-making system for ship collision avoidance mainly uses methods such as expert system, fuzzy reasoning, artificial neural network, fuzzy artificial neural network and evolutionary algorithm to make ship collision avoidance decision-making. Using these methods to solve the ship automatic collision avoidance decision-making problem has inherent limitations—these methods regard the solution process of the ship automatic collision avoidance decision-making problem as a "centralized" problem-solving process rather than a distributed problem-solving process. The "centralized" collision avoidance decision-making problem here means that these automatic collision avoidance decision-mak...
