抗冰海洋平台的全寿命优化设计I-理论与模型
|
摘要
文章基于投资—效益准则,建立了抗冰平台全寿命总费用最小的优化设计模型;考虑了多种类型的性能要求(结构、设备、人员),并建立了相关判据;提出了包括结构的初始费用、维修费用和期望损失费用的冰区海洋平台全寿命总费用评估模型;提出了平台结构主要功能的确定及描述方法、相应的功能失效损失值估计模型。
The optimum design model to minimize the expected life-cycle cost for ice-resistant platforms based on cost-effectiveness criterion is proposed in this study. Multiple performance demands under static and dynamic ice loads, such as structure, facilities and crew members, are treated. The related failure evaluation criteria, costs of construction, consequences of structural failure modes are formulated, in which the damage loss, repair cost, death and injury loss as well as discounting cost over time are considered.
