Abstract How does an information user perceive a document as relevant? The literature on relevance has identified numerous factors affecting such judgment. Taking cognitive approach, this study focuses the criteria users employ in making judgment beyond topicality. On basis of Grice's theory communication, we propose five‐factor model relevance: topicality, novelty, reliability, understandability, and scope. Data are collected from semicontrolled survey analyzed by following psychometric...

The concept of unmanned weapon system-of-systems (UWSoS) involves a collection various systems to achieve or accomplish specific goal mission. mission reliability UWSoS is represented by its ability finish required above the baselines given However, issues with heterogeneity, cooperation between systems, and emergence cannot be effectively solved traditional system methods. This study proposes an effective operation-loop-based evaluation method for analyzing dynamic reconfiguration. First,...

The product warranty has become an indispensable facet of business operations. Burn-in is effective at eliminating infant mortality and improving operational reliability levels for consumers. This paper considers the influence different failure states phases policies on costs from predelivery inspection to end period. We then propose a comprehensive cost model that burn-in, free replacement pro-rata as three repairable products presenting two types (minimal catastrophic failure) involve...

As one of the most typical multistate systems, weighted k-out-of-n system has been extensively studied in recent years. This paper presents a new kind system, which simultaneously considers performance requirements each component and (cumulative threshold all components). Then, we establish dynamic availability model by combining Markov process universal generating function. Moreover, an optimal design is proposed to achieve tradeoff between reliability/availability cost. Non-dominated...

The choice of maintenance strategy is a common problem in reliability engineering, and proper strategies can improve the efficiency save cost to some extent. There are many papers on selection optimization strategies. Most them considered from system level, ignored difference between different components. In fact, process each component aspects, such as time cost. Therefore, it necessary analyze perspective this paper, multi-objective model rate availability established under constraint by...

Abstract The constitutive model serves as the foundation for executing structure analysis to obtain deformation and stress/strain. In this paper, a neural network‐assisted Bayesian parameter identification framework is presented calibrate parameters of while considering unavoidable uncertainties. low‐cycle fatigue test CuCrZr alloy at 700 K first performed provide realistic data. posterior distributions are obtained by applying transitional Markov Chain Monte Carlo method. To accelerate...

Based on the insertion of internal and external redundant wires into L-type U-type wires, an efficient two-phase reliability-driven algorithm is proposed to insert construct local cycles protect failure any wire or via for yield improvement. For tested benchmarks, experimental results show that our approach increases extra wirelength by 18.3% 6.3% increase reliability 56.9% 5.2% improve chip 0.106 0.032 average in reasonable CPU time, respectively.

In recent years, system of systems resilience has been widely studied. System obvious properties when considering dynamic reconfiguration in the following four parts: avoidance, survival, adaption and recovery. can be downgraded recovered by reconfiguring resources to keep performance output enough satisfy threshold under internal failure or external shocks. other words, because reconfiguration, characteristics resilience. this study, first, a new model for based on is proposed. Second,...

Given a set of n buses with their possible escape directions to the available boundaries in pin array, firstly, layer assignment given same direction rectangle routing can be transformed into an interval packing problem. Based on optimality left-edge algorithm for packing, obtained by using concept density-reduction-oriented assignment. boundary, iterative approach proposed direction-constrained routing. Compared modified from Ma's approximation algorithm[10], experimental results show that...
