Manufacturing shop floor dynamics such as tool breakage or machine breakdown will disrupt the execution of planned production schedules. To deal with such disruptions, a multi-agent system (MAS) based approach has been considered as a means to perform a local rescheduling of affected manufacturing activities by dynamically allocating resources while guided by the objective of minimizing the impact...
With an increasing complexity of business processes, self-healing capability is becoming an important issue in order to support robust service flow execution. In this paper, a dynamic self-healing mechanism is proposed, which can dynamically identify suitable alternatives and replace faulty services such that a service flow can be performed successfully despite of unexpected exceptions. This mechanism...
Globalization leads to an efficient new business paradigm generally known as collaborative virtual enterprise (CVE) which demands flexible service orchestration and robust workflow execution. As two major service orchestration strategies, OWL-S and BPEL have their own strength and deficiencies. To meet the challenge in CVE, in this paper, we propose a workflow execution system (WES) that takes advantage...
Self-healing in workflow is becoming prominent because of the increasing software complexity. In order to support robust workflow execution, in this paper, we propose a self-healing mechanism to replace the faulty service dynamically. It is based on our previous research work -workflow execution system (WES). The OWLS2BPEL Mapper in WES is further enhanced to embed the self-healing mechanism into...
Collaborative virtual enterprise (CVE) is a new paradigm for industry and it imposes significant challenges on effective operation. In this paper, we formalized a top-down methodology for designing and developing service-oriented CVE with rich semantic support. This methodology facilitates automatic execution of virtual business process via service composition. The semantic notion is emphasized as...
Determining the service composition strategy suitable for service-oriented applications is an essential design issue. As a first step towards understanding service composition, in this paper, we present a comparison study with two different service composition strategies. One is driven by industrial application - BPEL, the other is inspired by the booming research development in semantic web - OWL-S...
Collaborative virtual enterprise (CVE) is a new paradigm for industry and it imposes significant challenges on effective operation. In this paper, we address the dynamic integration by leveraging the emerging Semantic Web services technologies. An integration architecture is introduced first for constructing a semantic-rich service-oriented CVE. A semantic-driven services composer based on the forward-chaining...
This paper proposes a technique for analysis and testing BPEL-based Web service composition using high-level Petri nets. To illustrate how these compositions are verified, the relationships between BPEL-based Web service composition and high-level Petri nets is constructed. By analyzing the structure of Web service composition based on BPEL, the corresponding HPN is constructed. The dynamism and occurrence...
