Impact on diabetes management of General Practice Management Plans, Team Care Arrangements and reviews

Objectives: To investigate whether General Practice Management Plans (GPMPs), Team Care Arrangements (TCAs) and reviews of these improve the management and outcomes of patients with diabetes when supported by cdmNet, a web‐based chronic disease management system; and to investigate adherence to the annual cycle of care (ACOC), as recommended in diabetes guidelines.

A-GATE: A System of Relay and Translation Gateways for Communication among Heterogeneous Agents in Ad Hoc Wireless Environments

The devices in an ad hoc network are expected to perform network functionalities by themselves due to the absence of proper networking infrastructure. Generally the routing is multi-hop as nodes may not be within the wireless transmission range of each other. This paper describes a system named A-GATE to support the high-level communication needs of agents in such a network. Agents are used to support the interoperability among devices and the system is capable of handling heterogeneity in agent platforms. A-GATE proposes a novel routing mechanism for locating the intended recipient of a message. The system aims to be self-organizing and self-configuring to suit the dynamic nature of ad hoc networks.

Goal-directed approach for process specification and service selection in customer life cycle management

Service selection is the first step in customer life cycle management where services are selected to meet a customer’s goals or objectives, personalised to the circumstances of the customer. The aim of this paper is twofold: (1) to develop concepts and algorithms for goal-directed service selection; and (2) to compare and reconcile our goal-directed approach with a service-oriented approach. The proposed goal-directed service selection algorithm is based on a goal-directed domain description that represents the customer objectives and the business processes. We use service component architectures with formalised contractual service process definitions as a software engineering approach to architectural design and realisation of service-oriented architectures (SOA). The comparison aims to understand the relationship between and benefits of a goal-directed approach and a service oriented approach . We use case studies from two complex customer care management domains to demonstrate the concepts. The implemented algorithms are tested in a health care case study.

Dynamically Refining the Task Models of Agents in a Multi-Agent System: A Less Communication Intensive Approach

Action selection of agents in a given environment is governed by the utility they gained from the resulting environment state. In a multi-agent system (MAS), the autonomy of agents can lead to a situation for multiple agents to perform similar or identical tasks if they independently try to maximize self utilities. Therefore, it is important to dynamically identify the autonomous capabilities of the agents in the MAS and modify them to avoid any task overlapping. This paper presents a less communication intensive corporation and coordination strategy for refining the task models of agents on the fly using a collective reasoning process.
