Published: May 2013

The fitting method is a basic method of computing power system dynamic security region (DSR) which uses orthogonal point-election method to determine directions when searching for critical points. It has high accuracy while its calculation speed is not fast enough for online application. In this paper, a directional rapid search (directional method for short) method is proposed.

Through a case of IEEE 10-39 system, the results verify that the maximum distance and angle between the hyper-planes calculated by fitting method and directional method are 0.06341 and 1.8447°.

When enough critical operating points in different search directions are acquired, the hyper-plane of DSR can be obtained by least squares fitting method. Simulation on IEEE 4-11 system shows that the suggested method is fast, reasonable, and practical.

Authors: Zhang Hua , Li Guang You , Li Chang Feng
Published: May 2013

This paper studies the auxiliary slot design technique for cogging torque minimization basing on an 8-pole/12-slot SPM servo motor. When the stator tooth coronas are unsaturated, the notching guidance given by analytical method can be testified effective in cutting down the cogging torque by FEM. But when the stator tooth coronas are saturated, the notching guidance is not effective any more. This phenomenon indicates that the saturation of stator tooth coronas has a significant impact on cogging torque.

Published: May 2013

DRAM industry is not only among the largest manufacturing industries in the world, but also the most competitive. Furthermore, due to DRAM business is characterized by short life cycles, along with highly competition, the manufacturers are forced to migrate to advanced technology quickly. Under this circumstance, the manufacturers have to launch new technology and purchase generational equipment to meet the market demand and reduce manufacturing cost frequently. This paper investigates the technology generational transition of DRAM industry from manufacturing and planning perspectives. The concept of TOC is applied to schedule the production plan of the new/old products. Regarding to shop floor control, three definitions of cycle time are used to diagnose the production status. Finally, the workload ratio of bottleneck is used for the release decision to adjust the rhythm of production.

Logistics informatization construction is vital to development of manufacturing enterprises. Choosing appropriate logistics informatization construction mode can make manufacturing enterprise save investment under the premise of ensuring their business requirements. Firstly, the paper divided manufacturing enterprises into process manufacturing enterprises, discrete manufacturing enterprises and hybrid manufacturing enterprises in accordance with the organization way of the production process; according to the scale they can be divided into micro-manufacturing enterprises, small and medium sized manufacturing enterprises and large (including group) manufacturing enterprises. Then summed up the main logistics informatization mode and generalized the construction mode of logistics informationization as follows: purchasing commercial software mode, enterprise independent development mode, outsourcing development mode, leasing mode and cooperative development mode. Finally studied different types of manufacturing enterprises should adopt what kind of construction mode of logistics informationization.

Published: May 2013

An Analytic Hierarchy Process (AHP) method was used to determine the key process in small batch trial process. Combining with the historical data of the key process in the product manufacturing process, similarity theory and data transformation methods, the data capacity relating to the product quality characteristics were enlarged. Through drawing a control chart of the process, the quality control in small batch trial process was realized.
The Dynamic Adjustment of China's Manufacturing Listed EnterprisesDebt Ratio - A Study Based on System GMM Estimation
Authors: Zhang Lei , Wu Bang Yuan , Wang Liang
Published: May 2013

The paper studies on adjustment conduct of Chinas manufacturing listed enterprises debt ratio from a dynamic perspective,and uses system GMM method to estimate focuses on 336 Chinas manufacturing listed enterprises dynamic panel data from 2002 to 2008. Results show that Chinas manufacturing listed enterprises have strong rationality and objective optimal debt ratio level. Companies can only make partial adjustment after deviating from optimal debt ratio level because of the adjustment costs,the adjustment speed is about 0.12,the corresponding adjustment half-period is 3.15 years,which is consistent with the traditional static trade-off theory.

Published: May 2013

The paper analyzes the optimal market structure and pricing strategy of regional logistics information platform based on bilateral market theory and network externality. Taking Zhejiang logistics information platform as an example, it establishes a two-stage (users gather stage, stable operation stage) regional logistics information platform pricing model. In the end, it draws a conclusion that the pricing strategy is mainly affected by platform service, network externality factor and user scale of both sides.
Research on Damping Properties of Seperated and Manually Adjustable Shock Absorber Oriented to Damping Matching
Authors: Song Da Feng , Yang Gong Ke , Du Chun Xiao
Published: May 2013

On the basis of the structure characteristics of the seperated manually adjustable damper and its working principles, establish the shock absorber mathematical model, at the same time, get test data and curves of seperated manually adjustable shock absorber damping characteristics by bench test. Use MATLAB to simulate the characteristic curve of the speed of the shock absorber based on the mathematical model. The simulation curves and experimental curves were compared to verify the correctness and accuracy of the model. Further simulation and analysis affect of parts of structural changes on the damping characteristics. In order to provide a theoretical basis to structural parameters designing and vehicle damping matching.
Emergency Logistics System Based on Bilevel Optimization Model

Published: May 2013

A bilevel programming model is established to determine the emergency storage centers location and the resource supply plan of the provincial and municipal levels by the collaborative mode of the vertical supply and lateral transfer for the emergency logistics system in the unusual emergencies. And the optimal solution is obtained by the hybrid genetic algorithm. Finally, the case shows the effectiveness of the proposed model and its algorithm.
An Improved Genetic Algorithm for Digital Facility Layout Optimization Oriented Multi-Species and Variable-Batch Production Mode
Authors: Li Dao Guo , Chen Zhao Xia
Published: May 2013

When solving facility layout problem for the digital workshop to optimize the production, the traditional genetic algorithm has its flaws with slow convergence speed and that the accuracy of the optimal solution is not ideal. This paper analyzes those weak points and proposed an improved genetic algorithm according to the characteristics of multi-species and variable-batch production mode. The proposed approach improved the convergence speed and the accuracy of the optimal solution. The presented model of GA also has been tested and verified by simulation.
