With the increasing demand of patients for limited healthcare services, e.g., expert physicians in general hospitals and the long on-site waiting time of patients, a real-time admission control (AC) policy was developed considering both distinction and fairness among heterogeneous patients. The AC policy chooses the customer for the next service from the waiting area to minimize the expected total...
Operating rooms are considered as the most valuable resource in hospital, which is important for the service quality to patients and the efficiency improvement in hospital operations management. This paper studies the week scheduling of operating rooms integrating other limited key resources including ICU beds and the workload of surgeons. A mixed integer program model has been proposed to optimize...
with the propelling urbanization and the rapid development of economy, society and city, and the teeming of question s on city' s development and construction cry for external, comprehensive, scientific analysis and evaluation of the development of the urban economy, especially the evaluation of investment value as soon as possible. In order to formation of a scientific and rational the evaluation...
In many business and scientific data warehouses, not only the data amount is growing in geometric series, but also the requirement of real-time capability is increasing. Database partitioning technique which adopts "divide and conquer" method can efficiently simplify the complexity of managing massive data and improve the performance of the system, especially the range partitioning. The...
This paper studies on the multi-attribute weighing decision model of grey target based on theories of decision-making analysis. Concerning of Savage decision criteria under the circumstance of uncertain decision, grey interval number series have been put forward to extend definition of real number series as well as a ranking method has been given according to the distance from Grey target. In this...
This paper introduced several abstract algorithms and analysed the existed problem, which the keyword's position was not enough considered in Lucene software package. Then this paper developed the dynamic abstract algorithm in Lucene software package. The new algorithm referred to the keyword's position in the content. The new abstract is exact. By testing, the developed algorithm is more effective.
