Our results show that health care costs significantly increase ...
This paper applies Benders decomposition to two-stage stochastic problems for energy planning with multiple climatic years, a key problem for the design of renewable energy systems. First, we implement Benders decomposition with existing enhancements suited for the characteristics of the problem, a simple continuous masterproblem and fewbut large sub-problems. Next, we develop a novel trust-region ...
