The Application of Risk Matrix to Acquisition Risk Evaluation for Weapon and Equipment
Li Zhongmin,Wei Yiming,Tang Shuchun,Chen Jian
Strategic Study of CAE 2006, Volume 8, Issue 6, Pages 95-99
Risk evaluation is the basis of acquisition management for weapon and equipment. Based on the totally analyzing and summarizing risk matrix widely used abroad, the paper firsdy discusses the application of risk matrix in acquisition risk evaluation for weapon and equipment in China. Then, the paper, beginning with the two rules of risk impact and risk probability, demonstrates risk evaluation of a type of weapon and equipment as a case study, thus lays a basis for the scientific and rational risk management decision making.

MCDB Monte Carlo dosimetry code system and its applications
Deng Li,Li Gang,Chen Chaobin,Ye Tao
Strategic Study of CAE 2012, Volume 14, Issue 8, Pages 72-77
MCDB is developed for boron neutron capture therapy (BNCT). This system consists of a medical pre-processor, a dose computation and a post-processor. MCDB automatically produces the input file from CT and MRI image data. In Monte Carlo dose calculation, several accelerated measures, such as the fast track technique, mesh tally matrix and material matrix, are developed. In this paper, we proposed a real model simulated by MCNP and MCDB, respectively. The almost same results as MCNP are achieved. MCDB is faster in computational speed than MCNP.
Keywords: MCDB fast tracking technique mesh tally matrix material matrix
Study on WBS matrix for construction management in urban rail-transi
Xie Lei1,Chen Qun,Yu Hua
Strategic Study of CAE 2010, Volume 12, Issue 1, Pages 102-107
To improve construction management in the urban rail-transit, the WBS concept is well exploited by crossing a horizontal breakdown of urban rail-transit construction activities with a vertical breakdown of its technology system, thus a WBS matrix is obtained, which is more complete and useful than the WBS tree. This article firstly stated the concepts of interface and WBS matrix, with urban rail-transit analysis of how to use WBS matrix to improve interface management. The composition, structure system and principle of WBS matrix were specifically analyzed by contrastive method. The handling efficiency of WBS concept was decided by the changing of the factors.

Strategic Study of CAE 2001, Volume 3, Issue 4, Pages 36-41
The model of complex cocurrent multi-effect evaporation with condensed water flash and extra vapor elicitation is established. The conventional model of cocurrent multi-effect evaporation is a simplified example of the model. A new algorithm (iteration method combining with matrix method) is presented. The results show that the new algorithm is which increases the convergent speed and stability, more efficient than the Newton method and Broyden method. With condensed water flash and preheating cane sugar solution from 26.7 to 90℃ by elicitation extra vapor,the fresh vapor expenditure of cocurrent three-effect evaporation is decreased by about 16%.

Strategic Study of CAE 2008, Volume 10, Issue 4, Pages 78-83
The drawback of classical matrix converter having low voltage transfer ratio is studied and a topology of a new matrix converter called as a Cuk matrix converter is proposed. The basic configuration of this new topology and its fundamental are firstly introduced, the analytic expression concerning functions relation of voltage transfer ratio to duty cycle is deduced, and the basic design method of double-loop control strategy is expounded. Finally the validity and feasibility of the new topology are tested by simulation.The results show that the output voltage and frequency can be modulated optionally by the new converter, of which the voltage transfer ratio can be greater than 1, or lower than 1, and an ideal sine wave can be directly obtained without filtering. Thus the inherent problem of classical matrix converter having low voltage transfer ratio is effectively solved by this study, which is of certain practical importance.
