Abstract
The healthcare organizations are facing a number of daunting challenges pushing systems to deal with requirements changes and benefit from modern technologies and telecom capabilities. Systems evolution through extension of the existing information technology infrastructure becomes one of the most challenging aspects of healthcare and the adaptation to changes is a must. The paper presents a change management framework for a citizen-centric healthcare service platform. A combination between Petri nets model to handle changes and reconfigurable Petri nets model to react to these changes are introduced to fulfill healthcare goals. Thanks to this management framework model, consistency and correctness of a healthcare processes in the presence of frequent changes can be checked and guaranteed.
Highlights
The traditional method of receiving healthcare required a patient to visit their doctor’s office, or a hospital; doctors, hospitals, and healthcare ecosystems are increasingly brought to the patient
Built upon Enterprise Service Bus (ESB) as an integration backbone [4], this paper presents a novel citizencentric healthcare service platform
This agent is in interaction with healthcare service platform to detect effective changes in the execution environment and map it into a Petri net model defined
Summary
The traditional method of receiving healthcare required a patient to visit their doctor’s office, or a hospital; doctors, hospitals, and healthcare ecosystems are increasingly brought to the patient. One of the much-touted potentials of this platform is the ability to construct healthcare composite Web services on demand, relieving telecom operators from the intricate details of how technologies work so they can focus on the business aspects. The proposed healthcare platform needs to achieve the plug-in/plug-out Web services with little overhead while guaranteeing properties. These properties can be classified either functional or non-functional. We use Petri nets to model handling and adaptive changes in healthcare platform. Petri nets can represent the safe an unsafe states of web services composition They represent changes between these states as transitions.
