Abstract Reliability assessment with adaptive Kriging has gained notoriety due to the Kriging capability of accurately replacing the performance function while performing as a self-improving function for learning procedures. Recent works on adaptive Kriging pursued to improve the efficiency of the active learning through the application of distinct learning functions, sampling methods, or frameworks to assess the learning space. Within this context, the present work exploits three innovative app...
Abstract Does security risk represent a higher global risk than natural disasters? Is flooding risk globally greater than infrastructure failure risk? Such questions are answered using global and national risk metrics and characterisations, for example as conducted by the World Economic Forum and many national safety and security agencies. The metrics and characterisations aim to inform decision makers, politicians and the public in general about serious hazards and threats that we face today an...

Abstract The concept of balanced systems has been evolved with many meanings recently, and the research on this topic is a hot and significant issue in the reliability field. In this paper, the system consisting of two components does not fail immediately when it is unbalanced. An imminent unbalanced state is defined that the system experienced before reaching its final failure. According to the sojourn time of the system in the imminent unbalanced state and the number of transitions from the ba...

Abstract In order to mitigate the detrimental outcomes of process anomalies, modern chemical plants are generally equipped with various safety interlocks. However, almost every conventional design was created by conjecturing the proper protective mechanism against a single abnormal event. In reality, multiple independent abnormal events may take place in many processes. Thus, there is a definite need to develop a systematic approach for designing the multi-event interlocks. In this paper, a real...
Abstract This paper presents a new variant of the selective maintenance problem (SMP) to jointly optimize the maintenance planning and resource allocation problems for multiple missions. The classical SMP deals with components and maintenance level selection with the aim of maximizing the system reliability given limited budget and break duration. Of the few papers dealing with the multimission SMP, none addresses the repairperson assignment problem. This work develops an SMP model for jointly o...

Abstract Resilience is often thought of as the ability to withstand a disruption and recover quickly from it. Thus, improving the resilience of an infrastructure system is often associated with reducing its vulnerability (related to the extent to which a network is disrupted), and increasing its recoverability (related to the speed of restoration). To address these concerns simultaneously, we propose a tri-level protection-interdiction-restoration problem for a system of interdependent networks,...

Abstract The redundancy allocation problem (RAP) has been widely studied, which aims to identify the optimal design to achieve the best system indicators, such as system reliability or availability, under certain constraints. This problem has been studied well in the single phased mission systems. But many practical systems, like the manmade satellites or spacecraft, perform a series of tasks in multiple, consecutive, non-overlapping time durations (phases). For these multi-phased systems, depen...

Abstract In supply chain systems, the entities supplier, manufacturer and distribution center make up the communication platform, which can obtain the data of production, stock, demand, etc. The cyber-physical system (CPS) typically involves multiple computational platforms interacting over communication networks. In the CPS, when the supply chain is disturbed and interruption occurs, supply chain resilience measurement is important to reduce order losses in the supply chain. In this paper, firs...
Abstract Resilience: a highly debated term, with what seems to be an endless amount of slightly varied definitions depending on the sector, domain, or researcher who is addressing the topic, mainly boils down to rebounding after a crisis. For critical infrastructure (CI), the EU-funded H2020 IMPROVER project used the following definition: “the ability of a CI system exposed to hazards to resist, absorb, accommodate to and recover from the effects of a hazard in a timely and efficient manner, for...

Abstract Many engineering systems are designed to complete two tasks simultaneously and therefore need to consider two interdependent performance measures. For example, a combined heat and power (CHP) system requires two interdependent performance variables of heat power and electric power to measure its reliability. The operation of such a two-interdependent-performance multi-state system (TIP-MSS) is usually constrained by a two-dimension feasible operating region (FOR) specific to the state. ...
