Channel assignment schemes in Multi-Radio Wireless Mesh Networks (MR-WMNs) usually leave several links sharing the same channel within overlapped transmissions or interference ranges; this is especially true when only one radio is used or when the number of radios is very small compared to the number of orthogonal channels. In this paper, we propose a new multi-objective optimization model for channel...

In some hospitals, logistic activities are planned based on the experience of people that are directly involved in them, which leads to question if this is or not, the best way to carry out the planning process. The mixed-integer linear programming model proposed...

An important activity in constructing a HOQ is to determine improvement ratios for the technical characteristics, based on the collected customer requirements, with a view to achieving a high level of overall...
