船舶安全熵概念的提出及应用

船舶航行安全很大程度上取决于操作者对船舶航行过程中各种信息的把握,信息掌握的多少可作为衡量船舶安全的一个标准。把船舶航行链分为5种信息处理过程,利用信息熵的原理,提出船舶安全熵的概念,并建立了数学模型。根据船舶航行信息过程的具体因素,建立船舶航行安全评价指标体系;利用熵权法确定5种信息单元及其安全因素权重,对船舶航行的安全熵进行计算,可根据评价模型对船舶安全进行有效评价。利用渤海湾船舶M进行验证,其结果发现船员素质安全熵最大。船舶安全熵方法是对船舶安全评估的一种新探索。

The Proposition of Ship Safety Entropy and Its Application

The safety of ship depends on the sailor's grasp of the information about ship sailing process,which is one of the standards measuring ship safety.The chain of ship sailing is composed of five information process in this paper.The concept of ship safety entropy is put forward based on information entropy theory,and its mathematical model is established.Then,an evaluating index system for the safety of ship sailing is set up according to the concrete information factors during sailing.Five information units and their weights of safety factor are decided by entropy weight method;thus,the safety entropy of ship sailing can be calculated out,which is very effective in measuring the safety of ship sailing.Taking ship M in the Bohai Gulf as an example,this model is illustrated.Ship safety entropy is a new exploration to evaluate safety of ships.
