Development of Quantitative Assessment Model of Achievement of Skill by Ship Handling Simulator Oriented Training and Suggestions to IMO regarding with How to Introduce the Ship Handling Simulator Oriented Training

环境压力模型的发展建立了一个定量模型，用于评估因操纵区受限、交通拥堵或两者兼而有之造成的船舶操纵困难。它包括基于海员安全感的验收标准。近失中模型的发展还建立了另一个表示船舶操纵过程中潜伏的未遂事件潜在危险程度的量化模型。海员技能成就的评估海员技能成就可以在海员技能成就评价表上显示，该评分表由环境应激模型得出的潜在环境应力值和近失中模型得出的险情发生率以及海员技能的实现过程组成。

The Development of Environmental Stress ModelA quantitative model for evaluating the difficulty of ship handling caused by a restricted manoeuvring area or by traffic congestion or by a combination of both was developed. It includes acceptance criteria based on the mariners' perception of safety.The Development of Near Miss ModelAnother quantitative model for expressing the degree of potential danger of near miss event latent in the ship handling process was also developed.Assessment of the Achievement of Skill of MarinersThe achievement of skill by the ship handling simulator oriented training for mariners can be indicated on the rating chart which is composed of the latent environmental stress value derived from the Environmental Stress Model and the occurrence rate of near miss danger derived from the Near Miss Model together with the achievement process of the mariner's skill.
