Alleviating human sufferings during and in the aftermath of disasters is one most important goals humanitarian relief logistics. The lack commodities, especially life-saving items, a life-threatening loss to victims must be considered when making emergency supply allocation transportation decisions, even pre-disaster prepositioning phase. This paper proposes scenario-based stochastic program th...

[1] An economical approach to improving predictions of hydrological models produced highly accurate representations of ephemeral and perennial stream networks. Traditional drainage network extraction from digital elevation models (DEMs) often yields inaccurate and inconsistent results because of elevation errors. Topographic wetness index maps calculated from alternative terrain representations...

Stock prepositioning is one of the most important issues in preparedness stage of emergency logistics response. In a previous research, a stock prepositioning model to support an emergency disaster relief response in the event of earthquake has been proposed. Since the results contained zero proportion of some type of item, which is not allowed in a real system, an improvement of the model is n...

ZigBee technology is a kind of self organization of short distance, strong anti-interference, low cost, emerging wireless sensor network application that has attracted wide attention. Therefore, this paper studies and designs a real-time positioning system of underground personnel based on ZigBee system, the positioning of the sensor carrying miners through the wireless sensor network. This wil...
