Real-time dispatching principle is a key technique of open-pit mine truck dispatching system. A new open-pit mine truck real-time dispatching principle which is under macroscopic control is proposed in this paper. Its advantages are considering the importance of object truck flow rates given by truck flow optimization substantially and controlling all of the actual truck flow rates to be approximate...
Supporting multicast applications has drawn increased attention in the development of WDM based optical networks. To provide a high level of availability in the face of node or link failure for multicast traffic, pre-assigned spare capacity in the networks is needed. This paper studies the problem of constructing a minimum-cost, two-connected subgraph, satisfying the wavelength conversion constraint,...
