The inhalable particulate matter (PM10) samples in environmental air was collected in 2008 during heating period and non-heating period at four sampling sites in the urban of Lucheng ciy. Applying 'nested chemical mass balance' and related environmental air particulate data in Lucheng city, the author successfully analyzed the contributions and ratios of individual sources to urban raised dust, the...
A Service supply chain occurs when a service provider outsources part of the service to a supplier. In service supply chains, as supplier offers service directly to final customers, it's hard for service provider to monitor or measure supplier's work. For this reason, the service provider has to offer an incentive mechanism to the supplier. This paper studies the optimal incentive mechanism in the...
Firstly, this article introduce foreign theoretical research of risk management in the subway tunnel project from four aspects that evaluation theory, management model, accident statistics, risk analysis. Secondly, the paper analyze foreign practice research of risk management in the subway tunnel project from four aspects that computer simulation, information platform, standards, government regulations...
The incentive problem in supply chain with asymmetric information is one of the important research contents. The existing supply chain research results are obtained under the condition that the amount of the principal's information is given, in fact, the amount of the principal's information is optional. Based on this understanding and the previous research results, this paper constructs a new monitoring...
The credit risk measurement of the Small and Medium Enterprises (SMEs) is a big problem in resolving their financing difficulties. In this paper, by improving the precision of parameters, we use the improved KMV model to identify the credit risk of listed SMEs in China. The model effectiveness test indicates that the KMV model after adjusting parameters is sensitive to the changes of credit risk,...
The paper analyze the Solow's efficiency wage model, Shapiro and Stiglitz's monitoring and shirking model, Salop's turnover costs model, Akerlof's adverse selection and gift exchange model, point out the defects of these models, suggest we should pay attention to the hypothetical condition and the limitation of these model; At last the paper discusses the developing directions of these models.
Logistics Finance is currently a new thing in china, which can promote capital flows during logistics finance business processes, it uses various financial products and services in the supply chain, and then improves efficiency of fund in supply chain. Logistics and finance combine into an innovative service, that is logistics finance which mission uses service, knowledge of supply chain and information...
Recently, both networking and high-performance computing technologies have dramatically advanced. As a result, scientists can access large-scale data captured by scientific measurement devices with ease. Also, recent high-performance computing technologies such as the Grid and cloud computing have allowed scientists to use huge computational power harnessed on the Internet for their analysis of scientific...
Realizing integrated financial management in supply chain is an inevitable trend. The features which integrated financial system in supply chain should have are expounded. Conception reengineering, process reengineering and organizational reengineering is premise to realize integrated financial management in supply chain. A framework of integrated financial system in supply chain is presented, which...
On the basis of multiple costumer projects restricted each other in the requirements and resources for the software organizations with complex business workflows, presents an organizational lever requirement management process oriented to multi-projects and the information support system. In the process solutions are framed against the requirements from various customers by consultation and service...
To promote the information technology development of the enterprise, achieve information integration and data share between different fieldbuses, by means of analyzing communication bus of industrial control system, the principle of the fieldbus protocol conversion is discussed. According to the basic construction of network, a scheme of fieldbus conversion is designed to accomplish the communication...
With the use of the advantages of computer and network technology, design and development of athletes information management systems achieve the basic information, evaluation, statistics of athletes, monitor and evaluate on the athletic ability of elite athletes and achieve information management of athletes automation scientific and management man-machine integration, and provide management of scientific...
In wireless sensor network studies the main objective is minimizing the energy consumption so that the lifetime is maximized under the limited battery capacity constraints. In most event-driven surveillance applications, the end-to-end delay should also be minimized. In this paper we present a new EDO-MAC (energy and delay optimization Media Access Control) which reaches a good balance between energy...
Due to the perfect management of hospital information system, the hospital staff could draw a better heal scheme for patients with the whole information when they take care of them. And hospital information in the medical environment has also played a key to the role to make patient have a convenient and efficient medical environment. These are the strong protection for the hospital flinty competition...
The requirements of transforming the centralized and one-way flow of control and information by energy service providers to the decentralized and two-way flow structure enabling plug-and-play are rapidly increasing. The importance of reliable, high-quality electrical power continues to grow as society enters into a new era of economics driven by digitally-based technologies. Enabling the digital economy...
As monitor plays a critical role in self-healing loop as the basis of self-healing, this paper proposes a comprehensive monitor model for self-healing systems on the basis of building model for general applications and organically combining monitor methods for different attributes of files. The monitor model can improve the performance of self-healing by reducing the grain size of monitor and recovery...
As the complexity of systems is rapidly growing, the designers are moving towards use system level design Languages (SLDL) such as SystemC and SpecC. In this paper we use SystemC and SpecC languages for modeling and simulation of wireless sensor networks (WSN). First we start on simple ECO model and add modular sections as increases as the complexity. In the next step, we add data encryption using...
Workflow Management System is a software system that runs on one or more work flow engines that used to define, implement and manage the workflow, interacts with workflow executors, facilitates the workflow instancepsilas execution and monitors the state during the workflow execution. Mobile Agent system supporting workflow management can make the distributed workflow in OA System more simple and...
