Since the publication of wash - 1400 report , probabilistic risk assessment ( pra ) has become an important method of risk assessment and management of complex engineering systems 自wash - 1400报告发表以来,概率风险评价( probabilisticriskassessment , pra )已成为复杂工程技术系统进行安全风险评估与管理的重要手段。
Engineering design problems generally involve several design objectives . these objectives , related to the technical and economical performance of the engineering system , are potentially conflicting in nature 工程设计问题一般都具有多个设计目标,这些与工程系统的性能或经济性等相关联的目标之间通常存在着内在冲突。
The fifth part : summary of the experience gained and lessons learned form the aircraft maintenance engineering system development process . the thesis is originated from the cswa aircraft maintenance engineering project 第五部分:对cswa公司飞机维修工程系统的实施经验及教训进行了总结,提出了系统存在问题和改进建议。
For example , petroleum chemical engineering systems and metallurgy systems can be modeled as time - delay systems for their content lag and transmission delay . and it is n ' t a rare phenomenon for several ten minutes of delay 如石油化工和冶金工业过程中的容量滞后和传输延时基本上是不可避免的,几十分钟的纯滞后现象也不算稀奇。
