Simulation and analytical tools are useful modeling methods to solve complex optimization problems. In this paper, we propose a simulation optimization framework called "Multi-fidelity Optimization with Ordinal Transformation and Optimal Sampling" (MO2TOS) when multi-fidelity models are available, and prove its efficiency by analyzing its convergence mechanism. The MO2TOS is a two-stage...
The imbalanced development among different levels of healthcare facilities has become a major social issue in China’s urban healthcare system, which has raised the irrational patient flow distribution on the levels of both intra-hospital and inter-healthcare facilities. In this research, we develop a methodology to find the optimal macrolevel patient flow distribution in terms of multidimension inputs...
Most streaming applications, such as multimedia and digital signal processing (DSP) application, are iterative in nature, so pipelined implementation can be introduced into streaming application for high throughput. In this case, as a communication-centric design approach, NoC is capable of solving communication bottleneck incurred by throughput increment. In this paper streaming application with...
As the community health care plays an important role in improving the health care equality and efficiency nowadays, It is one of the targets of the health care reform to establish a well distributed geographical community health network in China. In this paper, taking Haidian District in Beijing City as an example, the CHCs locations as well as the service allocation problem is solved by using an...
