Repairing and restoring disrupted components in an enterprise data center requires a significant amount of time and human effort. Following a major disruption, the recovery process involves multiple stages, and during each stage, the partially recovered infrastructures can provide limited services to users at some degraded service level. However, how fast and efficiently an enterprise infrastructure can be recovered de- pends on how the recovery mechanism restores the disrupted components, considering the inter-dependencies between services, along with the limitations of expert human operators. The entire problem turns out to be NP- hard and rather complex, and we devise an efficient meta-heuristic to solve the problem. By considering some real-world examples, we show that the proposed meta-heuristic provides very accurate results, and still runs 600-2800 times faster than the optimal solution obtained from a general purpose mathematical solver [1].展开更多

The China Yangtze Three Gorges Project Development Corporation has reported that contractors and other staff are working hard to ensure that the flood season does not slow the dam project. The company recently detailed the mammoth tasks that have taken place so展开更多

This is also an important part of the national Knowledge Innovation Program (KIP) spearheaded by CAS. Over the past two years, CAS has made a series of remarkable advances in Western China with regard to the development of research bases, exploration of crucial scientific problems, the training of talented people, and providing consultation services for decision makers.With the furtherance of the national drive to develop the country's western region, CAS will step up its efforts and increase its funding, to make more and greater contributions to the overall development of the region.展开更多
