Surveys suggest that supply chain risk is a growing issue for executives and that supplier reliability is of particular concern. A common mitigation strategy observed in practice is for the buying firm to expend effort improving the reliability of its supply base. We explore a model in which a firm can source from multiple suppliers and/or exert effort to improve supplier reliability. For both ...

We consider a cache-aided communications system in which a transmitter communicates with many receivers over an erasure broadcast channel. The system serves as a basic model for communicating on-demand content during periods of high network congestion, where some content can be preplaced in local caches near the receivers. We formulate the cacheaided communications problem as a joint cache-chan...

Clinical trials for primary prevention and early intervention in preclinical AD require measures of functional capacity with improved sensitivity to deficits in healthier, non-demented individuals. To this end, the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) was developed as a direct performance-based assessment of functional capacity that is sensitive to changes in function ac...

BACKGROUND Capacity building strategies are widely used to increase the use of research in policy development. However, a lack of well-validated measures for policy contexts has hampered efforts to identify priorities for capacity building and to evaluate the impact of strategies. We aimed to address this gap by developing SEER (Seeking, Engaging with and Evaluating Research), a self-report mea...

Traditionally, distributed Web servers have used two strategies for allocating files on server nodes: full replication and full distribution. While full replication provides a highly reliable solution, it limits storage capacity to the capacity of the smallest node. On the other hand, full distribution provides higher storage capacity at the cost of lower reliability. A hybrid solution is parti...

The past few years witnessed a rapid growth of interest in network reliability. This is because telecommunications services are now an integral part of businesses, national security, Md public health Md safety. Also, recent technological advances such as fiber optics high capacity digital switches and the increasing concentration of capacity in the telecommunications infrastructure have made ne...

This paper proposes an efficient algorithm to evaluate system reliability for many real-life systems such as manufacturing, telecommunication and computers systems. A multicommodity stochastic-flow network is constructed to model a manufacturing system in which each node stands for a machine station, and each arc stands for a transmission medium (shipping machine or conveyor). Four characterist...

Large-scale building structures are subject to numerous uncertain loads during their service life, leading a decrease in structural reliability. Real-time analysis and accurate prediction of reliability is key step improve the bearing capacity buildings. This study proposes an intelligent assessment method for driven by sustainability target, which incorporated digital twin technology establish...
