从坞容率的变化,分析中国修船能力预期和对策

文章根据国内修船坞容量的不完全统计数据,从船舶修理坞容率变化的观点,分析了中国修船能力的预期和建议及采取的对策,同时还介绍了新加坡的船舶修理和改装的情况,可供同行参考。

Modeling and Assessing a New Warship Maintenance System

The authors developed a prototype of a warship maintenance system. The process started by defining the maintenance requirements of warship equipment. Next, a planning scheme was development for a maintenance network. An optimization target for the plan and indexes for assessment were established. Based on the above work, a simulation model was proposed with two layers: a base and a workshop. Dispatching rules were then formulated for the simulation. Experimental results proved the validity of the model and the dispatching algorithm. It was found that the model can solve the capacity evaluation problem for maintenance systems and provides a scientific basis for decision-maker to make decisions regarding equipment maintenance.

模糊逻辑在修船规模决策中的应用

研究了确定修船基地设施规模的定量分析方法。根据修船业市场的特点,以修船规模与该地区港口吞吐量、修船价格的关系为基础,应用模糊逻辑理论建立了一个确定港口地区修船工业发展规模的决策模型。应用结果表明,模糊逻辑模型能够很好模拟新加坡、欧洲等修船工业成熟地区的修船规模,并得出上海港、宁波港、大连港地区的合理修船规模,为国内修船基地的建设提供参考依据。
