New exact solution approaches for the split delivery vehicle routing problem

EURO Journal on Computational Optimization, 2018
In this study, we propose exact solution methods for the split delivery vehicle routing problem (SDVRP). We first give a new vehicle-indexed flow formulation for the problem and then a relaxation obtained by aggregating the vehicle-indexed variables over

Relative humidity and its effect on aerosol optical depth in the vicinity of convective clouds

Environmental Research Letters, 2013
The hygroscopic growth of aerosols is controlled by the relative humidity (RH) and changes the aerosols’ physical and hence optical properties. Observational studies of aerosol–cloud interactions evaluate the aerosol concentration using optical ...
