A TCPN based approach to model the coordination in virtual manufacturing organizations☆

The recent developments of communication technologies and network computing have enabled the occurrence of the advanced manufacturing strategy—agile manufacturing. The essence of the agile manufacturing strategy is to form a virtual manufacturing organization (VMO), which integrates the core competencies of member enterprises in order to respond to the global market and increasing customer requirements rapidly. In a VMO, the manufacturing processes are distributed. So modeling and coordination of these processes are very complex. In this paper, we present a Petri Net based approach to model these distributed manufacturing processes and interaction relations among them. A workflow based manufacturing process execution environment is also established to support the implementation of the distributed manufacturing processes.

SwinDeW-a p2p-based decentralized workflow management system

Workflow technology undoubtedly has been one of the most important domains of interest over the past decades, from both research and practice perspectives. However, problems such as potential poor performance, lack of reliability, limited scalability, insufficient user support, and unsatisfactory system openness are largely ignored. This research reveals that these problems are mainly caused by the mismatch between application nature, i.e., distributed, and system design, i.e., centralized management. Therefore, conventional approaches based on the client-server architecture have not addressed them properly so far. The authors abandon the dominating client-server architecture in supporting workflow because of its inherent limitations. Instead, the peer-to-peer infrastructure is used to provide genuinely decentralized workflow support, which removes the centralized data repository and control engine from the system. Consequently, both data and control are distributed so that workflow functions are fulfilled through the direct communication and coordination among the relevant peers. With the support of this approach, performance bottlenecks are likely to be eliminated while increased resilience to failure, enhanced scalability, and better user support are likely to be achieved. Moreover, this approach also provides a more open framework for service-oriented workflow over the Internet. This paper presents the authors' innovative decentralized workflow system design. The paper also covers the corresponding mechanisms for system functions and the Swinburne Decentralized Workflow prototype, which implements and demonstrates this design and functions.

Supporting virtual enterprise systems using agent coordination

Open environments like the Internet or corporate intranets enable a large number of interested enterprises to access, filter, process and present information on an as-needed basis. These environments support modern applications, such as virtual enterprises and interorganisational workflow management systems, which involve a number of heterogeneous resources, services and processes. However, any execution of a virtual enterprise system would yield to disjoining and error-prone behaviour without appropriate techniques to coordinate the various business processes. This paper reports on the design and implementation of a flexible agent-based framework for supporting the coordination of virtual enterprises and workflow management systems. The paper also shows how an agent coordination infrastructure, which is explained by social constraints, can impact on the engineering of highly dynamic virtual enterprises and workflow management systems by presenting a simple case study.     

Context-aware workflow management for virtual enterprises based on coordination of agents

Although virtual enterprises (VE) make it possible for small flexible enterprises to form a collaborative network to respond to business opportunities through dynamic coalition and sharing of the core competencies and resources, they also pose new challenges and issues. Creation of VE involves dynamically established partnerships between the partners and relies on a flexible coordination scheme. The dynamic organizations formed in VE present a challenge in the development of a new methodology to dynamically allocate re-sources and deliver the relevant information to the right people at the right time. A key issue is the development of an effective workflow management scheme for VE. Multi-agent systems (MAS) provide a flexible architecture to deal with changes based on dynamic organization and collaboration of autonomous agents. Despite the extensive studies and research results on MAS, development of a design methodology to support coordination and operations is critical to the success and adoption of VE. The objectives of this research are to propose a design methodology to facilitate coordination and development of context-aware workflow management systems and achieve effective resource allocation for VE based on MAS architecture. To achieve these objectives, a scheme for coordination of agents is proposed. Petri net models are used in the coordination scheme to describe workflows and capture resource activities in VE. The interactions between agents lead to a dynamic workflow model for VE. Based on the aforementioned model, we propose architecture to dynamically generate context-aware graphical user interface to guide the users and control resource allocation based on the state of VE. An order management example is used throughout this paper to illustrate the proposed design methodology.
