Transportation time information plays an important role in transportation and logistics. Variability in transportation time is obvious in any mode of transport due to unpredictable system parameters and their dynamic behavior. Significant work has been done in transportation on road and rail modes but the area is still open and hot for maritime being less explored so far. This paper, in maritime perspective, defines the transportation time as time taken for all the activities from loading at source harbor till it’s unloading at the destination and so the return path. As uncertainties can be handled effectively by statistical methods, it is used for transportation time appraisal. The paper presents the methodology for maritime transportation reliability assessment and illustrates the same with an application to a case of Stena Baltica ferry operation in Europe. This paper uniquely combines quality and reliability tools in maritime studies and the obtained results are validated through the simulation. Further a leading link is taken to resolve the problem reducing the uncertainty level in the voyage by bringing process capability study into the investigation. Appropriate investigation and analyses with respect to transportation time variance reduction is also carried out in the paper.

海上运输时间可靠性评估

运输时间信息在运输和物流中起着重要作用。由于不可预测的系统参数及其动态行为，在任何运输方式下运输时间的变化都是显而易见的。公路和铁路运输方面已经进行了重大工作，但该地区仍是开放的，海上热火至今尚待探索。从海上角度来看，本文将运输时间定义为从源港口装货到在目的地卸货以及返回路径之前所有活动所花费的时间。由于不确定性可以通过统计方法有效处理，因此可用于运输时间评估。本文介绍了海上运输可靠性评估的方法，并在欧洲Stena Baltica轮渡业务案例中进行了说明。本文将海事研究中的质量和可靠性工具独特地结合在一起，并通过仿真验证了所获得的结果。此外，通过将过程能力研究纳入调查范围，可以解决降低航程不确定性的问题，这是一个领导环节。本文还对减少运输时间方差进行了适当的调查和分析。此外，通过将过程能力研究纳入调查范围，可以解决降低航程不确定性的问题，这是一个领导环节。本文还对减少运输时间方差进行了适当的调查和分析。此外，通过将过程能力研究纳入调查范围，可以解决降低航程不确定性的问题，这是一个领导环节。本文还对减少运输时间方差进行了适当的调查和分析。
