基于粗集理论的船舶静态权重评估模型
首发时间:2011-03-10
摘要:船舶的静态权重是航运调度问题中的重要参数之一,准确计算船舶的静态权重十分必要。为精确求解船舶的静态权重,本文对影响船舶静态权重的9个属性进行了分析。应用粗集理论处理船舶航运调度的历史数据,分析各个属性对船舶静态权重影响的大小,从而对文中所考虑的属性进行重要性排序。根据属性重要性排序的结果,本文建立了船舶静态权重评估模型,并举例求解船舶的静态权重。研究结果表明,应用粗集理论计算船舶的静态权重是有效的。

The Evaluation Model of Ships' Static Weight Based on Rough Set Theory
Abstract:Ships' static weight is one of the important parameters on the shiplock scheduling problem, which is essential to be evaluated. To calculate ships' static weight accurately, nine properties are considered in this paper. Rough set theory is used to deal with the historical data of shipping scheduling, according which the nine properties is sorted by their importance. Accroding to the analysis result, evaluation model of ships' static weight is bulit in this paper. The study result shows that rough set theory is effective in calculating ships' static weight.
Keywords: rough set lower approximation set attributes dependence ships' static weight
