讲座人简介:张玺,北京大学工业工程与管理系副教授,研究领域主要集中于工业与服务系统的实时监测、诊断、优化。曾在IISE、JQT、IEEE T-R、IEEE T-ASE等国际知名期刊发表多篇学术论文。
讲座内容简介:通过传感网络所获取的时空数据为工程系统状态建模和监测提供了前所未有的契机。然而,在利用时空数据对系统进行建模过程中往往存在数据不完备和质量不一的情景,这些都直接削弱了模型对工程系统状态估计的精确性和对系统监测的时效性。本次汇报主要介绍研究团队在利用不完备时空数据建模的一些研究进展,将分别以储备粮温度场估计和预测为研究对象进行时空建模方法的阐述。

讲座内容简介:In many real production systems, a system may be stopped due to a lack of demand or exhaustion of raw materials. This is known as production wait and provides a good opportunity for maintenance. Meanwhile, the increased complexity of the modern machines brings new challenges for modeling and analyzing their failure behaviors. To address these real-world problems, this research considers a single-unit system that may fail due to either hard failures or soft failures. The wait time of a system is utilized to conduct inspections or maintenance. The system is replaced when a defect is found during an inspection, a failure occurred or a pre-specified age threshold is reached, whichever comes first. The cost model, which is the long-run maintenance cost per unit of time, is derived. The optimal periodical inspection interval and the threshold age to minimize the long run maintenance cost per unit of time is then obtained. A case study is conducted to demonstrate the proposed maintenance model. The study shows using the proposed maintenance model can reduce the cost. Sensitivity analysis illustrates how each cost parameter affects the optimal inspection interval and the optimal age threshold.

讲座内容简介:Cyber risks are the most common risks encountered by a modern networked system. Among various characteristics, propagation should be one of the most important characteristics of cyber risks. On the assumption of risk propagation, the assessment of cyber risks, namely, the size of compromised nodes after certain types of incidents, has been studied for a long time in the literature. However, most of them only focus on the limiting behavior or approximation of size of compromised nodes of large-scale networks and ignore some important elements of risk management such as the heterogeneity, dependence and so on, which may cause a limited application. In this talk, we focus on the accurate distribution and dependence of sizes of compromised nodes in an arbitrary network based on the proposed L-hop propagation model: (1) we provide a recursive algorithm for the multivariate distribution of sizes of compromised nodes with different types as well as explicit formulas; (2) we characterize the dependence of the sizes from both qualitative and quantitative perspectives. Specifically, we prove that it always possesses the positive association dependence among the sizes and provide explicit formulas for computing the covariance of sizes and a certain global dependence measure. Moreover, we will present the effects of parameters including propagation depth L and compromise probabilities on the joint distribution and dependence. Some results and useful insights for certain specific network topologies including complete and star will be highlighted.
