Web service composition problem was considered as a planning problem by previous research. However, many factors constantly affect the QoS and results of invocation of web services, thus the environment of web services is dynamic. As result, web service composition problem should be considered as an uncertain planning problem. This paper uses Markov property to deal with the uncertain planning problem...
How we manage Web services depends on how we understand their variable parts and invariable parts. Studying them separately could make Web service research much easier and make our software architecture much more loose-coupled. We summarize two variable parts that affect Web service compositions: uncertain invocation results and uncertain quality of services. These uncertain factors affect success...
Traditional method to assesse the equipment support operational skill is by locale examining and examinant experience, it is presented of evaluation method based on traininging process data and k means clustering, and a calculating case is validated. The case shows the arithmetic is used to support operational skill evaluation, whose indexes are quite comprehensive. Historical data of daily traininging,...
The cable stayed bridge is one of the main types of long span bridge with greater crossover capability and a good economical benefit. Introduced the structural analysis theory of cable stayed bridge construction control, summarized the simulation analysis methods of cable stayed bridge construction control, and described their own characteristic. The structure simulation analysis and calculation during...
Morphological analysis is an important process in the design of cable-membrane structure. This article describes the analysis method of cable-membrane structure, a detailed analysis and discussion of the non-linear finite element method for form-finding method and obtain the concrete steps to use ANSYS software to achieve the form-finding analysis. Finally, through the combination of a pre-tensioned...
