The objectives of this research program are to develop and test new techniques in Condition Based Maintenance with imperfect information and ultimately introduce new Risk-based inspection and maintenance policies for physical infrastructures. **First, we will introduce optimal replacement/repair policies for equipment with imperfect information, when partial repair is an option. Application of Data-Fusion in maintenance optimization with imperfect information will be investigated as well. **Finally, we will address some infrastructure risk and maintenance management problems. Maintenance planning and risk management of ageing physical infrastructures, such as roads; bridges; and power supply networks, is an appealing research field in developed and developing countries. Infrastructure owners and operators strive for continuous improvement of their systems and staff development. This ensures that they are able to meet and exceed users' need, that they are cost-efficient and effective in the use of resources, and are meeting the applicable environmental and safety/risk regulations. The proposed research program will apply a risk-based maintenance approach to provide risk-efficient methods for physical infrastructure maintenance planning. **

这项研究计划的目标是开发和测试基于不完全信息的状态维护新技术，并最终为物理基础设施引入新的基于风险的检查和维护政策。**首先，当部分维修是一种选择时，我们将引入不完全信息设备的最优更换/维修策略。研究了数据融合在不完全信息下维修优化中的应用。**最后，我们将解决一些基础设施风险和维护管理问题。老化的有形基础设施（如道路）的维修规划和风险管理；桥梁;而供电网络，在发达国家和发展中国家都是一个很有吸引力的研究领域。基建业主及营办商致力持续改善系统及员工发展。这确保它们能够满足甚至超过用户的需要，确保它们在资源使用方面具有成本效益和效果，并符合适用的环境和安全/风险法规。拟议的研究计划将应用基于风险的维护方法，为物理基础设施维护计划提供风险有效的方法。**
