从分布式、真实的实时的角度研究了多船避碰决策支持模型。在COLREG规则和法规的一般要求下，以图形方式分析了让路船和站立船在一些典型相遇情况下的避碰变向和变速性能。在此基础上，根据本船与目标船的相遇情况，做出改变航向或改变航速避碰的初步决策。设计了线性延拓算法，用于改变航向和降低航速，以保持本船应避开的所有目标船的间隙。仿真结果表明，当所有船舶都遵守COLREG规则，以及其中一些船舶不采取行动时，避碰公式可以避免碰撞。结果还表明，在多船会遇情况下，一船违反COLREG规则有时会给其他船舶的避碰带来更大的困难，同时不得不采取不必要的操纵行动。(C)2015爱思唯尔有限公司版权所有。
A multi-ship anti-collision decision support formulation is studied in a distributed and real time way. Under the general requirements from COLREGs rules and regulations, the performance of course alteration and changing speed in collision avoidance in some typical encounter situations is graphically analysed for both give-way and stand-on ships. Based on the analysis, the initial decision on collision avoidance by course alteration or speed changing is made according to the encounter situation between own ship and target ships. Linear extension algorithms are designed for both course alteration and speed reduction to keep clearance of all the target ships that own ship should avoid. Simulation results indicate that the anti-collision formulation can avoid collision when all ships have complied with COLREGs as well as when some of them do not take actions. The results also show that in multi-ship encounter situations, the violation of COLREGs by one ship can sometimes bring more difficulties to other ships to avoid collision while undesirable manoeuvre actions have to be taken.
