Office environments have recently adopted ubiquitous computing for collaboration and mobile communication to promote real-time enterprises. Ubiquitous offices, introduced by Weiser and adopted as emerging computational technology to support office works, have already affected the practice of companies and organizations. Within this context, this study deals with a work service model of the ubiquitous office environments by understanding human behaviors and works in their workspace. We propose a ubiquitous office model considering the correlation between ubiquitous computing technologies and work services in the office. Two attributes are emphasized, collaboration and mobility, as identifiers for categorizing the work types. The types of work services have variations in the amount of communication and the proportion of working outside of the office. The proposed work service model of the ubiquitous office includes territorial and non-territorial services to enable workers in and out of the office to interact with each other effectively. The findings in this paper would be a theoretical basis for embodying an intelligent office which supports office works efficiently. 展开更多

In the last five years, China has seen the technological development of intelligent mining and the application of the longwall automation technology developed by the Longwall Automation Steering Committee. This paper summarizes this great achievement, which occurred during the 12th Five-Year Plan (2011-2015), and which included the development of a set of intelligent equipment for hydraulic-powered supports, information transfers, dynamic decision-making, performance coordination, and the achievement of a high level of reliability despite difficult conditions. Within China, the intelligent system of a set of hydraulic-powered supports was completed, with our own intellectual property rights. An intelligent mining model was developed that permitted unmanned operation and single-person inspection on the work face. With these technologies, the number of miners on the work face can now be significantly reduced. Miners are only required to monitor mining machines on the roadway or at the surface control center, since intelligent mining can be applied to extract middle-thick or thick coal seams. As a result, miners' safety has been improved. Finally, this Darter discusses theprospects and challenges of intelligent mining over the next ten years. 展开更多

Buying work safety services from intermediaries is a new and important approach to improve the work safety in small and medium-sized enterprises(SMEs).The existing literature addresses the significance and effectiveness of the service model but it ignores the dynamic game relationship between relevant stakeholders when SMEs choose to purchase the services under bounded rationality.Therefore,this study aims to analyse this dynamic game relationship based on evolutionary game theory.Furthermore,dynamic simulations of the evolutionary game model are applied to determine the impact of major factors for three stakeholders(SMEs,governments,and safety service agents),examine stability strategies,and identify modes of equilibrium under different subsidy strategies.The results of simulation are as follows.First,the results explain that how the major factors(service price,the quality of service,government subsidy,etc.)affect the system dynamic force of buying work safety services.Second,when the subsidy strategy is static payment,the selection of the stakeholders fluctuates and is not optimal.Third,when the subsidy strategy is a dynamic payment,the evolutionary game process converges to a stable state,which indicates that an evolutionarily stable strategy exists under the dynamic subsidy strategy.Moreover,the stable state and equilibrium values are not affected by the different initial values.The results of this study offer a certain reference for the government to guide the implementation of the purchase of work safety or other services in SMEs. 展开更多
