Due to the advantages of being able to function under harsh environmental conditions and serving as a distributed condition information source in a networked monitoring system, the fibre Bragg grating (FBG) sensor network has attracted considerable attention for equipment online condition monitoring. To provide an overall conditional view of the mechanical equipment operation, a networked service-oriented condition monitoring framework based on FBG sensing is proposed, together with an intelligent matching method for supporting monitoring service management. In the novel framework, three classes of progressive service matching approaches, including service-chain knowledge database service matching, multi-objective constrained service matching and workflow-driven human-interactive service matching, are developed and integrated with an enhanced particle swarm optimisation (PSO) algorithm as well as a workflow-driven mechanism. Moreover, the manufacturing domain ontology, FBG sensor network structure and monitoring object are considered to facilitate the automatic matching of condition monitoring services to overcome the limitations of traditional service processing methods. The experimental results demonstrate that FBG monitoring services can be selected intelligently, and the developed condition monitoring system can be re-built rapidly as new equipment joins the framework. The effectiveness of the service matching method is also verified by implementing a prototype system together with its performance analysis. 相似文献

Despite the significant role that multiparty international joint ventures (MPIJVs) play within multinational enterprises, we know little about the significant challenges associated with the management of these ventures. Therefore, we combine the Resource-based View of the Firm and Transaction Cost Economics to investigate the effects of the key aspects of partner diversity (i.e., variety, balance, and disparity) on MPIJV dissolution. We test our hypotheses using a dataset of 248 MPIJVs in China. We find empirical support for a U-curve shaped effect of variety and a negative linear effect of balance on MPIJV dissolution. 相似文献

This paper reviews the theoretical foundations of the equity based foreign market entry (FME) decisions literature. We analyse 1055 academic FME papers published over four decades (1970–2013). We identify and analyse the theories that informed and guided FME research over time. Our review indicates that scholars have recently started to challenge some of the core assumptions of established theories, draw on and integrate insights from multiple theoretical perspectives which, in turn, generated a multiplicity of approaches for studying FME decisions and their performance outcomes. The paper discusses the explanatory power of the different theories, assesses the relevance of the different theoretical perspectives to our understanding of current FME phenomena and recommends directions for further research. 相似文献

This study examines the effect of meeting space capacity on hotel operating performance. We use Resource-Based View (RBV) of the firm as the theoretical foundation. We employ a national-level dataset with more than 20,000 hotels in the United States for the 2007–2012 period. We find that meeting space has a non-linear effect on hotel operating performance. That is, at low levels of meeting space, meeting space capacity is negatively related to hotel operating performance. At high levels of meeting space, meeting space capacity has a positive influence on operating performance. These findings provide insights for hotel owners, developers and practitioners in planning hotel meeting space capacity. 相似文献

This research note highlights the novelty of integrating location-based services (LBS) available on Smart Phones and Tablets into traditional resident attitude survey methodologies such as door-to-door data collection. It specifically reviews how the LBS technology available on mobile devices can be used to systematically capture GPS coordinates of one's residence and integrate this captured spatial information into software such as ArcGIS and SPSS for further analysis. By having GPS coordinates associated with respondents' answers, researchers have an additional layer of information available for conducting a multitude of tests previously not possible with subjective categorical spatial data. Two research applications using the spatial location of residences are provided as examples of how LBS available on mobile devices can be integrated within resident attitude projects. The use of LBS technology can help researchers better understand how the distance residents live from major tourist attractions influences their attitudes towards tourism. 相似文献

This paper discusses an optimal investment, consumption, and life insurance purchase problem for a wage earner in a complete market with Brownian information. Specifically, we assume that the parameters governing the market model and the wage earner, including the interest rate, appreciation rate, volatility, force of mortality, premium-insurance ratio, income and discount rate, are all random processes adapted to the Brownian motion filtration. Our modeling framework is very general, which allows these random parameters to be unbounded, non-Markovian functionals of the underlying Brownian motion. Suppose that the wage earner’s preference is described by a power utility. The wage earner’s problem is then to choose an optimal investment-consumption-insurance strategy so as to maximize the expected, discounted utilities from intertemporal consumption, legacy and terminal wealth over an uncertain lifetime horizon. We use a novel approach, which combines the Hamilton–Jacobi–Bellman equation and backward stochastic differential equation (BSDE) to solve this problem. In general, we give explicit expressions for the optimal investment-consumption-insurance strategy and the value function in terms of the solutions to two BSDEs. To illustrate our results, we provide closed-form solutions to the problem with stochastic income, stochastic mortality, and stochastic appreciation rate, respectively. 相似文献

An important step in the internationalization process of emerging economy firms is the shift from exports to foreign direct investment (FDI). We integrate the resource- and institution-based views to suggest that firms that can use unique institutional advantages are more likely to make this shift. We test these arguments with a longitudinal sample of 28,563 firm-year observations (1989–2005). We found that firms that are affiliated with a business group, have more firm- and group-level international experience, have more technological and marketing resources, and operate in service industries are more likely to shift from exports to FDI. 相似文献

Previous literature has studied telework practices predominantly from the employees' perspective rather than exploring its use at the firm level. With the objective of contributing to reducing this research gap, the relationship between firms' adoption of telework and the firms' technological, organisational and environmental contexts is explored. Data were obtained from a survey conducted between 2005 and 2009 on a sample of 1,134 Italian firms in the Piedmont region. The results show an overall increase in the diffusion of telework primarily attributable to a rise in the adoption of ‘mobile’ work rather than home‐based forms of telework. The results also show that firms that had previously adopted information systems supporting core business processes and knowledge management were more inclined to adopt telework. Telework arrangements were more widely diffused among firms facing a growing and geographically dispersed market demand, and also in the contexts of higher levels of human capital and lower capital intensity. 相似文献
