考虑了工程系统的基于风险的检查（RBI）计划。由于难以为系统的RBI制定计算上可处理的方法，迄今为止，大多数程序只侧重于单个组件或仅以非常简化的方式考虑系统效应。一些研究指出了在检验计划中考虑系统效应的重要性。特别是对于大型工程系统，如果系统中各种类型的功能和统计依赖关系没有明确地处理，则不可能确定成本最佳解决方案。基于单个部件RBI的新发展，本文提出了一种综合方法，用于考虑整个系统的检查计划。提出并讨论了系统中依赖关系的各个方面，随后介绍了结构系统检查和维护计划中遇到的决策问题。然后展示了如何用决策理论模型一致地表示这些决策问题。最后给出了钢结构疲劳检测规划的实用程序。
Risk based inspection (RBI) planning for engineering systems is considered. Due to difficulties in formulating computationally tractable approaches for RBI for systems, most procedures hitherto have focused exclusively on individual components or have considered system effects in a very simplified manner only. Several studies have pointed to the importance of taking systems effect into account in inspection planning. Especially for large engineering systems it is not possible to identify cost optimal solutions if the various types of functional and statistical dependencies in the systems are not explicitly addressed. Based on new developments in RBI for individual components, the present paper presents an integral approach for the consideration of entire systems in inspection planning. The various aspects of dependencies in the systems are presented and discussed, followed by an introduction to the decision problems encountered in inspection and maintenance planning of structural systems. It is then shown how these decision problems can be consistently represented by decision theoretical models. The presentation of a practical procedure for the inspection planning for steel structures subject to fatigue concludes the paper.
