Problem definition: In this paper, we study a reliable hub location model, the objective of which is to minimize the associated costs plus the penalty for unserved demands. The model assigns to each origin-destination pair a primary path and a backup path to hedge against the risk of random...

As processing difficulty associated with a product increases, information about a subsequently encountered product becomes easier to process, leading to more favorable evaluations of it (a contrast effect). If, however, the two products are categorized as part of the same overall experience,...

It is well-known that adding a little flexibility to the right place is an effective strategy to improve the performance of operations in the face of demand uncertainties, to ensure high level of capacity utilization. However, given that system disruptions are ubiquitous, the legacy flexibility...

We study the reliable (uncapacitated) facility location (RFL) problem in a data-driven environment where historical observations of random demands and disruptions are available. Owing to the combinatorial optimization nature of the RFL problem and the mixed-binary randomness of parameters...

The Y1-xMgxNi 2.1 (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) alloys were prepared by the sintering method. XRD, EPMA, and Sieverts’methods were used to study the influence of Mg partial substitution of Y on the alloys phase structure and hydrogen storage properties. It was found that with the...

The cognitive procedure that people use to search for information about a product is influenced by the ease with which it comes to mind. Unrelated experiences can activate a search process that governs the order in which favorable and unfavorable product descriptions are identified and the...
