Covering problems are well-studied in the domain of Operations Research, and, more specifically, Location Science. When location space is a network, most frequent assumption to consider candidate facility locations, points be covered, or both, finite sets. In this work, we study set-covering problem when both locations and demand continuous on network. This variant has received little attention...

Cutting plane methods play a significant role in modern solvers for tackling mixed-integer programming (MIP) problems. Proper selection of cuts would remove infeasible solutions the early stage, thus largely reducing computational burden without hurting solution accuracy. However, major cut approaches heavily rely on heuristics, which strongly depend specific problem at hand and limit their gen...

In this paper, the interface crack of two non-homogenous functionally graded materials is studied. Subsequently, with employing the displacement method for fracture of mixed-mode stress intensity factors, the continuous variation of material properties are calculated. In this investigation, the displacements are derived with employing of the functional graded material programming and analysis o...
