Electric Grid Vulnerability Analysis to Identify Communities Prone to Wildfires

open access: yesIEEE Access, 2023
Natural hazards, like wildfires, present various challenges to the electric grid that can leave many communities without power. To identify vulnerabilities in the grid and the corresponding at-risk communities, this work considers the implementation of ...

The inverse maximum flow problem with lower and upper bounds for the flow [PDF]

open access: yesYugoslav Journal of Operations Research, 2008
The general inverse maximum flow problem (denoted GIMF) is considered, where lower and upper bounds for the flow are changed so that a given feasible flow becomes a maximum flow and the distance (considering l1 norm) between the initial vector of bounds ...

Inverse Minimum Cut Problem with Lower and Upper Bounds

open access: yesMathematics, 2020
The inverse minimum cut problem is one of the classical inverse optimization researches. In this paper, the inverse minimum cut with a lower and upper bounds problem is considered. The problem is to change both, the lower and upper bounds on arcs so that
