Building Flexible and Cooperative Applications Based on e-Services
نویسندگان
چکیده
Designing and controlling cooperative applications composed from e-Services poses new and complex research problems. In the present paper, a model for specifying cooperative applications based on e-Services is proposed, which allows representing both statical and dynamic aspects of cooperating e-Services, and orchestration specifications in a dynamically evolving distributed environment. The characteristics of a run-time architecture for supporting flexible application executions are discussed. Substitution of e-Services with other ones with similar characteristics both at design-time and at run-time is discussed. Orchestration is performed without the need of centralized control on the flow of activities, thus allowing peer-to-peer interaction between cooperating organizations.

متن کاملManipulation Control of a Flexible Space Free Flying Robot Using Fuzzy Tuning Approach
Cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. During such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. Therefore, to design and dev...
متن کاملSupporting Trusted Data Exchanges in Cooperative Information Systems
In cooperative processes and in e-services, an evaluation of the quality of exchanged data is essential for building mutual trust among cooperating organizations and correctly performing cooperative activities. Several quality dimensions, related to the intrinsic nature of data and to the context of the cooperative process where data are used, must be taken into consideration. In addition, in o...
متن کاملGenerating Versioning Facilities for a Design-Data Repository Supporting Cooperative Applications
Nowadays the complexity of design processes, no matter which design domain (CAD, software engineering , etc.) they belong to, requires system support by means of so-called repositories. Repositories help managing design artifacts by offering adequate storage and manipulation services. Some of the most important features of a repository are version management and activity management. Versioning ...
