A fast hybrid primal heuristic for multiband robust capacitated network design with multiple time periods

Fabio D'Andreagiovanni, Jonatan Krolikowski, Jonad Pulaj
2015 Applied Soft Computing  
We investigate the Robust Multiperiod Network Design Problem, a generalization of the Capacitated Network Design Problem (CNDP) that, besides establishing flow routing and network capacity installation  ...  Since the resulting optimization problem may prove very challenging even for instances of moderate size solved by a state-of-the-art optimization solver, we propose a hybrid primal heuristic that combines  ...  Specifically, we adopt Multiband Robustness, a new model for Robust Optimization recently introduced by Büsing and D'Andreagiovanni [14] ; 2 a hybrid primal heuristic, based on the combination of a randomized  ...

Path Planning for Autonomous Landing of Helicopter on the Aircraft Carrier

Hanjie Hu, Yu Wu, Jinfa Xu, Qingyun Sun
2018 Mathematics  
To obtain a reasonable landing path, a multiphase path planning algorithm with the pigeon inspired optimization (MPPIO) algorithm is proposed to adapt to the changing environment.  ...  The results demonstrate that the helicopters can all reach the ideal landing point with the reasonable path in different situations.  ...  For example, to solve the capacitated network design problem (CNDP), a robust optimization model based on multiband robustness was proposed, and a hybrid primal heuristic was developed [37] .  ...

Hybrid Offline/Online Methods for Optimization Under Uncertainty

Allegra De Filippo
Due with both offline and online decisions: an energy management system with uncertain renewable generation and demand, and a routing problem with uncertain travel times.  ...  In this context, at each stage some uncertainty is revealed and some decision must be made: the need to account for multiple future developments makes stochastic optimization incredibly challenging.  ...  For the online phase itself, we use instead a fast greedy heuristic.  ...
