the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

A hierarchical Bayesian learning framework is proposed to account for multi-level modeling in structural dynamics. In the system considered as a hierarchy of lower-level models, starting at lowest material level, progressing component then subsystem before ending up level. and uncertainty quantification techniques based on measurements that rely data collected only level cover quite limited num...
