We computationally assess policies for the elevator control problem by a new column-generation approach for the linear programming method for discounted infinite-horizon Markov decision problems. By analyzing the optimality of given actions in given states, we were able to provably improve the...

We consider the online bounded-batch scheduling to minimize total weighted completion time on parallel machines. In the problem, a set of n independent jobs arriving online over time has to be scheduled on m given machines, where the information of each job including its processing time and...
