Recently in electricity markets, a massive focus has been made on setting up opportunities for participating demand side. Such opportunities, also known as demand response (DR) options, are triggered by either a grid reliability problem or high electricity prices. Two important challenges that...

A Location-Routing Problem (LRP) combines two difficult problems, facility location and vehicle routing, and as such it is inherently hard to solve. In this paper, we propose a different formulation approach than the common arc-based product-flow (Arc-BPF) approach in the literature. We...

In the paper Li et al. [A robust branch-and-cut approach for the minimum-energy symmetric network connectivity problem. Omega 2012;40:210–7] it is claimed that a theoretical result appeared in Montemanni and Gambardella [Exact algorithms for the minimum power symmetric connectivity problem in...
