Compared with real-world polling, election prediction based on social media can be far more timely and cost-effective due to the immediate availability of fast evolving Web contents. However, information from social media may suffer from noise and sampling bias that are caused by various factors and thus pose one of biggest challenges in social media-based data analytics. This paper presents a new...
The importance of network organizations gets theoretical and practical recognition. Governance performance in network organizations mainly reflects a region coordination ability and competition ability. However current empirical work has paid little attention to what kinds of dimensions arrangements really do reflect governance performance and reduce transaction costs. Based on the Caofeidian enterprises...
The pressure to shorten product development process has increased due to rapidly changing technology and customers' perceived needs. Many researchers address reducing product development time. These methods are, however, still time-consuming not well-structured. The push-pull model of product development flow (PPM-Flow) in this paper is concurrent-based analysis model by combining forward with backward...
In 1998, Nahapiet and Ghoshal combined social capital and intellectual capital to study the influence mechanisms of corporate social capital towards intellectual capital creation, and put forward corresponding theoretical model. However, this theoretical model has not been verified so far. In this study, specific data of Chinese enterprises, SPSS, and structural equation are used to verify this model...
IT service quality has been proved important to IS success, but former researchers used to consider IT service quality and information system quality as two independent factors, the relationship between the two factors were never studied .The goal of our study is to understand the link between them, and help organizations manage their system better. SEM and SERVPERF instrument were used in our study.
Virtual Community and E-commerce are both new research area which is becoming popular in IS academia. In most of research papers, virtual community and e-commerce are talked separately in different stream. Since many e-commerce websites contain a virtual community, we combine these two together to consider whether discussions in virtual communities can influence people's online shopping behaviors...
In allusion to the shortcoming of the traditional AHP (analytic hierarchy process) method which requires consistency checking and judgment matrix rectifying frequently, an improved AHP that does not need consistency checking is proposed. Based on 4 main performance indexes, i.e. energy utilization, economic performance, reliability and environment impact, and 9 sub-indexes in total, the model of an...
FPGAs are applicable to implementation of fault tolerant systems due to their reconfigurability. Such fault tolerant systems can be classified according to recovering methods: fail-soft and standby-redundant systems. In this work, we propose a probabilistic model for both FPGA-based fault tolerant systems, and analyze the reliability and performance of the systems. Analytical results show that there...
The urban rail transit which has large capacity will become main transfer way and change the structure of transfer to certain extent in urban railway passenger hub. The research on the influencing factors for choosing urban rail transit is premise for the optimal arrangement of capacity on urban rail transit which matches with transportation demand in urban railway passenger hub. According to the...
The paper started from analyzing the background of the development of headquarter economy in Xi'an Hi-Tech Industries Development Zone (ldquoXi'an High-tech Zonerdquo for short) and the literature review of financing efficiency , and took the effect that financial services system had on corporate financial efficiency as the research object. The research took high-tech enterprises, financial institutions'...
Based on the researches of the perceived risks in the Web, we construct a model to deal with the perception how to influence customers to buy in the field of C2C . Then, get 192 effective questionnaires through Internet survey. It is proved store risk, product risk, and delivery risk are 3 dimensions of C2C consumers' risk perception. The effects of product risk influence consumers' purchasing intention...
Evaluation of service quality is becoming more important in the field of retailers, as in other fields. This pilot study is a preliminary attempt to develop an evaluation model by using exploratory factor analysis (EFA), analytic hierarchy process (AHP) and fuzzy comprehensive appraisal (FCA). And then it addresses issues associated with determining the service quality in a retail store environment...
Trust is a fundamental concern in large-scale open distributed systems such as multi-agent systems. It lies at the core of all interactions between the entities that have to operate in such uncertain and constantly changing environments. In this paper, an approach is developed for the evaluation of trust using fuzzy reasoning. The approach takes different trust sources into account, thereby minimizing...
This research is to probe into the jeans' brand image. In this study, we regard the brand image sources as the input, the customer's brand loyalty as the output and the brand asset valuator (BAV) model as the middle treatment of procedures, and then build a full model for evaluating the brand image for jeans. This model probes into three components of brand image in terms of image of product, image...
The running equipment of industrial system may be affected by not only the conditions of the system but the operating state itself, so that the risk of equipment failure was considered as dynamics. During researching the possibility and severity of the failure risk, it is necessary to understand and investigate the dynamic characteristics of equipment failure in the system life cycle. In this article,...
Virtual enterprise is the outcome of fierce competition in the world market. The selection of partners is one of the key factors for the success of virtual enterprises. Multi-agent system is an incompact agent federation composed of many agents, with its characteristics identical to virtual enterprises. It is, therefore, reasonable and effective to apply to the selection of enterprises' partner. The...
Research projects of SNCF (French railway) aim at reducing the costs of infrastructure possessions and improving the operational equipment availability and safety. This permanent search for a better regularity led the SNCF to analyse the maintenance approach of signalling equipment in detail. Until now, it was commonly acknowledged that signalling equipment, which consists of many electronic devices,...
This research paper tries to add trust and Guanxi into the western frame of supplier selection to explain the mechanism of supplier search in China. On the basis of this analysis we make a number of recommendations for improvement of firmpsilas order getting capabilities in China.
We consider the problem of supply chain coordination when the supplier is unreliable. By unreliable, we mean the supplier that with some probability delivers an amount strictly less than the amount desired. We formulate the decision models under the quantity flexibility contract model with unreliable supply. The analysis results show that the quantity flexibility contracts with unreliable supply can...
With the development of economy and urbanization in China, Property Management of residence (PMR) has been playing more and more important role in people's living. Service quality of property management of residence (SQPMR) and how to evaluate it have increasingly been become the focus of social attention as well. However, in real life, people usually use qualitative method to estimate SQPMR. The...
