In this paper, we study a passenger-taxi queueing systems in which nonzero matching time is considered. We assume that passengers and taxi drivers who arrive at a taxi station independently form two queues, and the waiting space for taxis is limited. We use a two-dimensional Markov process to model the system. By using matrix-analytic method, we give a sufficient condition that ensures the existence...
Semantic Web services (SWS) and business process management (BPM) technologies are gradually applied in many domains like electronic commerce and enterprise application integration, which has unavoidably led to the requirements and concerns for effectively recovering from kinds of failures, especially in complex, untamed and dynamic Web environments. Generally, Exception handling is considered to...
Semantic connection is reflect the correlations between services on business logics and is considered as one of most important elements for the automated discovery, composition, and execution of Web service. In order to explicit description the semantic connection of Web services and using it into semantic Web service research domain, we analysis the semantic link between input message and output...
Semantic Web Service technology provides a strong support for automation software development based on Web service. By analyzing the existing description models and methods of semantic Web service, a Semantic Web Service Description Model (WSDM4S) and its formal description based on SHOIN+(D) are proposed, which attempt to offer an effective model for description, publication, discovery, composition,...
In recent years, semantic Web service technology has gradually become the hot issue of academia and industry, for it can annotate Web service with semantic information to realize the automatic discovery, automatic composition and invocation. However, nowadays there is lack of ontology used to describe the semantic information of Web service directly, which results in the no basis and hard operation...
Complex service-oriented enterprise application needs compose Web services to satisfy user specific requirements. Several approaches have been proposed to fulfill this need. However, those approaches and their runtime infrastructure are weak in providing flexible features such as dynamism and adaptability, which are needed in mobile networks and wireless scenarios. A semantic programming language...
