为满足煤炭和铁矿石海运贸易流量预期的增长，干散货码头需要进行设计或扩建。目前缺乏一种针对干散货码头的综合设计方法。当前的设计是基于经验法则、实践经验以及特定设计标准的平均值。在这项研究中，对现有设计方法进行了补充，并开发了专用的模拟模型以支持设计过程。这些模型包括日常运营中出现的随机过程和操作程序。为实现精确的码头设计，需要考虑随机变化，如船舶到达时间和载货量的变化、物料在堆场的存储时间以及设备故障等。由于不同码头任务之间存在相互依存关系，对整个码头运营进行建模是复杂的。这就是为什么将码头分解为子系统的原因。对每个子系统分别进行分析，并为每个子系统开发模拟模型。最后，将模拟模型合并为一个单一的码头模型。模拟模型在（重新）设计的制定和评估中被证明是成功的。
To meet the expected increase of seaborne trade flows for coal and iron ore dry bulk terminals need to be designed or expanded. A comprehensive design method for dry bulk terminals is missing. Designs are currently based on rules-of-thumb, practical experiences and average values for specific design criteria. In this research, additions to existing design methods are formulated and dedicated simulation models are developed to support the design process. These models include stochastic processes and operational procedures that occur during daily operations. Stochastic variations take need to be taken into account to realize accurate terminal designs are the variations in ship arrival times and shiploads, the time that material is stored at stockyards and equipment disturbances. Modeling the entire terminal operation is complicated due to dependencies between the different terminal tasks. That’s why the terminal is decomposed in subsystems. Each subsystem is analyzed individually and per subsystem simulation models are developed. At the end, the simulation models are merged into a single terminal model. The simulation models proved to be successful in the formulation and assessment of (re)designs.
