E-business based maintenance, repair and overhaul (E-MRO) is a new MRO service mode. Although in real world there are a number of E-MRO prototype systems, few comprehensive studies have been conducted on this topic. Motivated by the challenges of making optimal E-MRO service planning, simultaneously considering the capacity constraints of MRO service providers and the maintenance constraints of equipment...
In order to solve the transformation problem of BOM from engineering BOM to maintenance BOM for MRO system (MRO, Maintenance, Repair and Overhaul), a formal transformation model of BOM view is established. In this model, the intermediate component, inherit component, virtual component are defined on the specific maintenance management domain, and the transformation process from engineering BOM to...
Glycerol is a model whose ingredients are dominant in bio-oil, that is the reason why this thesis chooses glycerol as the model to pyrolyze biomass into oil. The thesis adopts coprecipitation method to produce a series of Ni-based catalysts, researches the rules and principles of restructuring glycerol into hydrogen in gasification reactor and explores the reaction conditions and reaction principles...
Developing high quality education has been as a basic state policy, and teacher education is also been placed on the key and prior position to carry out in many countries. Conducting effective teacher education becomes a main way to improve the level of teachers' specialization and classroom teaching quality. The development of modern information technology perfects the construction of web-based teacher...
Zijin Mountain National Forest Park in Nanjing City was selected as the study area and pine wilt disease was chosen as the monitoring object. High resolution remote sensing images of QuickBird in 2004 and 2007 were collected as the primary information source, while level two forest inventory data in 2007 were used as the auxiliary information. After image procession of change detection between 2004...
The field of financial cost analysis and decision is a conceptually rich domain where information is complex, huge in volume and a highly valuable business product by itself. The eXtensible Business Reporting Language is an XML vocabulary designed to simplify the automation of exchanging financial information, and to enable the automatic extraction of financial and cost information by software applications...
This paper adopts a contingency perspective to investigate the relationship among cluster density, external search, and innovation performance of high-technology ventures. Specifically, this study argues that local density and external search have both separate and joint effects on a firm's innovation performance. To test our hypotheses, we draw a three-year sample from the Zhongguancun Science Park...
This paper reports the findings of a new distributed infrared biometric sensing approach in lightweight human identification. Pyroelectric infrared (PIR) sensor arrays are employed in infrared biometric sensing while the vector quantization (VQ) based algorithm is developed for identifying walkers in the context of the path-constrained walking. The main contribution of this paper is twofold. First,...
This paper applies the legitimacy perspective to examine the financing of technological start-ups in a transitional economy. In particular, this study identifies five key factors that help technological start-ups build up their legitimacy: R&D investment, conformity to ISO9000, affiliation with research institutions, state-owned enterprise, and firm size. Empirical findings from 11,154 new technological...
This is the pilot study of adopting system dynamics model and method to demonstrate the organizational inertia of knowledge-intensive business services in perspective of dynamic evolution. This study aims to establish the causal feedback constructs and the corresponding dynamic models. It reveals that the motivation of enlarging the dimensions of organizational inertia from the structural inertia...
A customer win-back model is developed to test the relationship among customer relationship management, commitment, and customer loyalty in this paper. This model involves customer relationship management, trust, emotion, price, commitment, loyalty and other factors. A number of data analyses are carried out, and the results show that customer relationship management has a positive impact on the formation...
This paper aims to build the model based on system dynamics (SD) theory, test its internal consistency, and explore the brief dynamic implications of a theory that relates to evolutionary paths of organizational inertia. This is the initial research of adopting system dynamics model and method to demonstrate the organizational inertia of biomedicine industry in the perspective of dynamic evolutionary...
E-commerce provides both opportunities and risks to SMEs. The objective of this study is to identify the state of use of e-commerce and the factors that influence the level to which SMEs use e-commerce. A research model is postulated that contains eight potential independent variables and hypotheses under three broad categories - technological, organizational and environmental characteristics. The...
A good numerical non-point source pollution model is an efficient tool for non-point source pollution management, which can be used to analyze the temporal and spatial rules of pollutant discharge. In this paper, SWAT model is adopted to estimate the contribution of non-point source pollution in the Xiangxi River watershed of Three Gorges Reservoir Area in China in 2002-2007a. With the predicted values...
In electric power system, long term peak load forecasting plays an important role in terms of policy planning and budget allocation. The planning of power system expansion project starts with the forecasting of anticipated load requirement. Accurate forecasting method can be helpful in developing power supply strategy and development plan, especially for developing countries where the demand is increased...
