The paper presents the framework for agent-enabled dynamic web service composition. The core of the methodology is the new understanding of a web service as an agent capability having proper ontological description. It is demonstrated how diverse web services may be composed and mediated by dynamic coalitions of software agents collaboratively performing(More)
The paper presents our intermediate results in ontologizing a refined formal representation of environments, events, and happenings elaborated in PSI project. This ontology is used for agent-based modeling of engineering design systems and processes. Our formal approach is inspired by discrete event calculus (DEC). In difference to DEC based on discrete(More)
One way to make engineering design effective and efficient is to make its processes flexible – i.e. self-adjusting, self-configuring, and selfoptimizing at run time. The paper presents the descriptive part of the Dynamic Engineering Design Process (DEDP) modeling framework developed in PSI1 project. The project aims to build a software tool assisting(More)
Works on ontology versioning pay special attention to the logical analysis of ontology evolution. The paper considers extensible declarative approach to ontology change description. Metric temporal description logic with metric temporal modalities “future n” and “past n” and hybrid satisfaction operator @ is proposed as the logical basis for declarative(More)
Presented is the vision of the authors on how diverse web services may be composed, mediated by dynamic task coalitions of agents performing tasks for service requestors. The focus and the contribution of the paper is the proposal of the layered web service mediation architecture. Middle Agent Layer is introduced to conduct service request to task(More)
Researches today pay keen attention to the problems and the methods of virtual (as well as real) enterprise modelling. Growing interest to these problems may be explained by the expansion of distribution and virtualisation in manufacturing and other business processes (rapid growth of diverse “hows” for doing real business by virtual means electronic(More)
The paper presents PSI1 Meta-Ontology – an upper level lightweight descriptive model for the set of the Core ontologies of PSI Suite. While PSI Suite is an interlinked modular library of ontologies describing the domain of engineering design performance in microelectronics, PSI Meta-Ontology is more domain-independent. It is an upper-level model of stateful(More)
