In distance education, communications among students, educators, and administrators have been one of the most important problems. The distance education programs in The Open University of Hong Kong (OUHK) span not only Hong Kong but also many cities over a large area in China. To improve and monitor the quality of communications among students, tutors, and staff, we propose a communications management infrastructure based on an alert mechanism. Requests and messages in these systems (referred to as alerts) have to be delivered and handled timely to provide ubiquitous distance education communication support and management. We also propose using this platform for the integration of partners in China with the OUHK offices. Presently, most systems cannot address urgency and alerts are often handled in an ad-hoc manner. In this paper, we propose a sophisticated alert management system (AMS) for ubiquitous communications management in distance education under various requirements. We develop a model for managing alerts, in which alerts are associated with communication tasks and a set of parameters are captured for message routing and urgency management. The AMS matches the specialties of the educators and staff who receive an alert, based on the alert specification. We then propose a routing mechanism that is initiated when the alert message is not acknowledged or handled within the deadline, so that the alert can be re-routed if necessary. Monitoring is

Abstract. E-service/process composition requires allocating suitable resources to a set of services that constitute a composite service/process. The problem is complicated due to undetermined constraints of each component service and unpredictable solutions by service providers. It needs the ability to rapidly identify the suitable solutions or resources as well as effectively to coordinate them under various constraints. Thus, an agent-mediated coordination framework for e-service/process composition is proposed. Each agent works as a broker for each service type, posting service request, searching suitable solutions and refining service constraints for achieving coherence among solutions to each service. Based on the framework, a prototype of multi-agent supported e-supply chain composition is implemented. The experimental results indicate the significant effectiveness of this approach. 1
Dynamic Supply Chain Integration through Intelligent Agents
"... The success of supply chains depends on the match between the requirements and offerings that deliver the services.

The success of supply chains depends on the match between the requirements and offerings that deliver the services. It can be ensured by separating requirements from the means of realization as well as dynamically assigning available resources to requests. To achieve this, we need coordinate the flow of information among the services and link their business processes under various constraints. Existing approaches to this problem have relied on complete information of services and resources, and have failed to adequately address the dynamics and uncertainties of the operating environments. The problem is complicated as a result of undetermined requirements of decomposed individual services and unpredictable solutions contributed by service providers. This paper examines an agent-mediated coordination approach to dynamic supply chain integration. Each agent works as a broker for each service involved in the chain, exploring service requests as well as identifying suitable resources for achieving compatibility and coherence among the decisions of individual services. Based on the approach, a prototype has been implemented with simulated experiments highlighting the effectiveness of the approach. 1.

The contemporary workplace is characterized by all kinds of (synchronous and asynchronous) human interactions both within and across organizations like meetings, discussions, consultations, conversations etc. Although such interactions are an essential part of a modern organization’s business processes, current research on business processes focuses mainly on the sequence of activities or tasks within a process (i.e. workflows), and not on human interactions. This research presents an application of an interaction-centric process modeling language named TALL for collaboration processes (CPs). For the illustration and evaluation of the language, a case study of a real-life CP is presented. The case study concerns the collaborative work of a Dutch municipality in relation to young persons who drop out from school. Shortcomings of existing workflow-based languages in the modeling of CPs are elicited. In the case study, the language is shown to address these shortcomings. The main strengths of TALL are (1) the visualization of human interactions, their roles and agents, and their relationships in a process-oriented tree diagram, and (2) the explicit recognition and specification of the local behaviors of the agents who are assigned to play the roles in a given interaction. Evaluation results are discussed. These results comprise practical insights, and contributions to theory and language development.
