E-Service Composition: Models and Formalisms
نویسنده
چکیده
The emerging paradigm of electronic services promises to bring to distributed computation and services the flexibility that the web has brought to the sharing of documents. An understanding of fundamental properties of e-service composition is required in order to take full advantage of the paradigm. This paper examines proposals and standards for e-services from the perspectives of workflow, process models, and automata theory. Key areas for study are identified, including behavioral models of services and their compositions, techniques for verifying properties of compositions, and techniques for synthesizing compositions. A sampling of emerging results and techniques in each of these areas is presented.

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies
In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

متن کاملDefinition und Realisierung einer Plattform zur modellbasierten Komposition von Simulationsmodellen
Modular hierarchical modeling formalisms distinghuish clearly between simulation algorithms and model definitions and offer well-defined means to construct models flexibly. At the same time they are particularily aimed at a centralized development of models. In contrast, simulation-based integration approaches clearly separate interface descriptions from model implementations, but offer less su...
متن کاملAI planning - based semantic web service composition
Semantic web service composition constitutes the phases namely specification, matchmaking, planning, validation, discovery and execution. As web service composition is categorised as an AI planning problem, the objective of this paper is to propose a fluent calculus approach for the planning phase of the semantic web service composition. Among various methods to solve the AI planning problem, l...
متن کاملModeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism
In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...
