PLM (product lifecycle management) is the management of the enterprise's products all the way across their lifecycles in the most effective way. However, at present, the PLM system in the market is not very appropriate to the small and medium-size enterprises. This paper presents a workflow engine-driven universal PLM system framework, which is constructed by four layers: client layer, application...
In this paper, we propose a novel approach SDR-CS (Sparse Dimensionality Reduction based on CS) based on compressed sensing to reduce dimensionality. With certain constraint of objective function, our semi-supervised learning method utilizes instance to construct the optimally sparse dictionary in the training dataset, employs K-SVD and OMP algorithms to improve the convergence rate of learning, and...
Workflow Engine is the core component of Workflow Management System. According to the standards of Workflow Management Coalition, this paper uses Petri net as the principle model, divides the Engine system into five functional modules,adopts Java EE Distribute Object Computing technique,thread poll control mechanism and BeanShell script interpreter technique to give the design and implementation solution...
Currently, the calculation of similarity in ontology mapping is unilateral and complicated, because of this, it has resulted in many issues such as the calculation of similarity are not reliable. In this study, we had got a new similarity algorithm for the concepts from different ontologies: we not only considered the influence of name, instance, attribute, and structure of the concepts in designing...
Business intelligence is a key means to promote core competence of enterprise. However, the enormous construction cost of business intelligence severely limits the popularization and development of business intelligence. The multi-agent technology provides a feasible solution for construction of low-cost business intelligence system. Firstly, this paper introduces the current applied status of business...
This paper analyzes the effects of energy price shocks from a general equilibrium standpoint of the features of modern business cycles. This study modifies a typical real business cycle model with indivisible labor by explicitly including energy as a productive input and modeling the relative price of energy as an exogenous random process. In closed models, the production technology of firms is described...
Generally, when an earthquake occurs, rescue operations cannot be effectively conducted timely due to the interruption of communications. This paper proposes a novel communication approach, wireless mesh network (WMN) communication, which can provide network access for emergency rescue services after the earthquake to satisfy the communication requirements of rescue work. Simultaneously, when the...
By using the quarterly data of 1996-2005 in China, we use a dynamic stochastic general equilibrium modeling framework to compare the different design of monetary policy: an interest rate feedback rule and a money growth rule. Drawing on our econometric analysis, we argue that model, closed with interest rate feedback rule comes closer to the data. The paper also suggests to incorporate the sticky...
In the context of ERP implementation, leadership is consistently found to be the most important factor leading to implementation success. However, most of the studies focus on leader's strength and authority while ignoring the important role leader's personal charisma plays in the implementation process. In addition, there is a lack of study on the underlying process of how leadership acts during...
This paper uses a version of Hansen's (1985) real business cycle (RBC) model to mimic Chinese business cycle from 1996 to 2005. The comparison of simulation results and actual data implies that the model can reflect economic fluctuations. Quantitative analysis demonstrates that technology shock contributes to more than 90.3% of Chinese economic fluctuations, and RBC model is an ideal framework for...
Based on the China economy data 1996-2005, two issues are addressed in this paper. First, we examine the ability of the DSGE model to describe stylized facts about China economy. The model succeeds to replicate the variability observed in 1996-2005. Second, we compare two methods of motivating money in DSGE Model. Drawing on our econometric analysis, we argue that the cash-in-advance model, closed...
The purpose of this paper is to study the operational competitiveness of Chinese state-owned manufacturing enterprises (CSOME) by analyzing the case CSOME and comparing with other global manufacturing companies in a global manufacturing strategies (GMSS) database. Analytical models are used to analyze the operational competitiveness of the case CSOME based on the weights of the multi-criteria manufacturing...
This paper presents a thorough case study and analysis aiming at studying operational competitiveness of Chinese high-tech international manufacturing company (CHTIMC). In this paper, some models are applied: (1)analytic hierarchy process (AHP) method is used to analyze questionnaires, which are got from the case CHTIMC, of multi-focused manufacturing strategies; (2)the analytical models, which can...
In respond to the challenge of complexity and variability that business information systems are facing nowadays, this paper proposes a solution of architecture combining service-oriented architecture (SOA) and business process management (BPM). First, we explain the definition, characteristics and implementation of SOA; second, we introduce the concept and mechanism of BPM; finally, we give an overall...
The paper focuses on the evaluation of the development situation of commercial service industry in Beijing. First, the evaluation indexes are established, and the grey correlation method is used to analyze the correlation degree on the commercial service industry indexes. Then, the elastic coefficient model of commercial service industry in Beijing is established to compare the development level of...
