Agent-based service composition has provided a promising computing paradigm for the automatic web service composition. In this paper, a formal service agent model is proposed, which integrates the web service and software agent technologies into one cohesive entity. Based on the service agent model, a distributed planning algorithm for web service composition called DPAWSC is presented. DPAWSC formalizes...
The topic of agent-based service composition has been experiencing much attention. In this paper, a service agent model is proposed, which integrates the Web service and software agent technologies into a cohesive entity. Based on the service agent model, a distributed agent coalition algorithm for autonomic Web service composition named as DACA is proposed. DACA is fully distributed, which is based...
An agent-based Web service workflow model is presented in this paper to facilitate the autonomic Web service composition, which contains three layers. The top is the user layer which represents the service requirements as goal workflow, the bottom service layer denotes the distributed Web services, and the middle is the agent layer. Each service agent in the agent layer abstracts the features of a...
In order to survive in today's competition intensive market, the enterprises should streamline their business processes and improve them constantly. In the paper, the way to design cooperative agents for business process management is introduced. In this method, as the first step, business process models are identified and designed. By decomposing the process model, the agent model can be generated...
To improve the efficiency of Web service integration, an agent-based Web service workflow (ABWSWF) model is proposed. ABWSWF model contains three layers. The top is the user layer which represents the service requirements as goals, the bottom service layer denotes the distributed Web services, and the middle is the agent layer. Each service agent in the agent layer abstracts the features of a group...
With the improvement of the traffic complexity extent, the solution of traffic problems becomes more and more difficult in the reality, so traffic simulation is an effective method for analyzing the traffic states and problems. As the simulation area becomes larger and more complicate, which requires large computing and storage resources, it can't be resolved by the traditional computing technology...
Grid computing is becoming a mainstream technology for large-scale distributed resource sharing and system integration. Workflow management is also emerging as one of the most important grid services. Web service composition has been one of the hottest research topics. Grid environment is very dynamic, and the services are shared among many users, it is impossible to optimize the workflow from the...
Traffic congestion has become a major concern for many cities throughout the world. Simulations provide useful tools for engineer to plan traffic systems and government to make decisions. The microscopic traffic simulation approach defines the behavior of each interactive object in the traffic network, such as a vehicle and a traffic light through an individual model so that we can observe the detail...
