Primary care, the backbone of the nation’s healthcare system, is at the risk of collapse. Patients are dissatisfied due to poor access to care, and physicians are unhappy and burning out with an enormous amount of tasks. To improve the primary care access, many healthcare organizations have introduced electronic visits (or e-visits) to provide patient-physician communications through securing messages...
This paper presents a method for deadlock-freeness scenarios detection in Web services composition. This method considers the Petri nets theory and is based on the analysis of Linear Logic proof trees. To detect the deadlock-freeness scenarios, a Linear Logic proof tree is built for each different scenario of the modules from which the composed system is built. These proof trees are analysed and some...
Change Impact analysis and propagation have widely been studied in Software engineering research, but most studies are related to monolithic software applications, and very few studies have focused on distributed environments. Newer technologies like SOA, BPM and Cloud demand different perspectives and newer tools and techniques to support impact analysis and propagation in distributed environments...
Business Process Modelling (BPM) is a way to support business processes by using several techniques, methods, models, and systems to design, control and analyse business processes, where many resources are used: humans, technologies, organizations, applications etc. The current existing literature describes several BPM techniques; however, these techniques are often hard for IT people to understand...
This paper analyzes the connotations and characteristics of WSVE, puts forward the integration framework and process of virtual enterprise based on WEB service with target on the change of enterprise demands so as to shorten the time for the identification and organization of virtual enterprise, find out suitable partners among large number of available potential partners, strengthen the autonomy...
The present generation business world does not work as a standalone system but requires the collaboration of various enterprises to achieve a desired goal. These enterprises are designed on the paradigm of web services and the maintenance of these web services is an implicit requirement. The maintenance of the services include extending the existing service, reusing the available services and remodel...
This paper, aiming at enterprise integration between virtual enterprises, presents a concept of web service-based virtual enterprise (WSVE) and integrated framework and model for WSVE. This paper proposes a modeling structure for WSVE, including target view, organization view, function view, resource view and process view, and for process view which integrates all other views, presents a value timed...
Constructing Web service workflow faces huge challenges in the volatile, heterogeneous, distributed environment: it is necessary to consider the dynamic changes in web services, but also take into account the rapid method of modeling workflow. Comparing workflow modeling and artificial intelligence planning process, if the Web service as a planned action (or activity), then the modern AI planning...
As the consensus of using web services as an alternative to traditional deployment models has been growing during the last years, also new techniques to face the new arisen problems have been developed. In this work, we present the design of a conference management system by using a composition of web services as deployment model. We bring our attention about the management of contributions observing...
In the distributed cross-organization business process, each organization only knows its private orchestration and partial public choreography, It doesn't have any information about the global process. If one organization has to change, it is difficult to compute the impact imposed on other organizations. In this paper, we propose a method to get the global services dependency matrix automatically...
We discuss a learning model that enables the creation of optimal learning strategies that suit learnerspsila needs. A customized learning content is delivered to learners as managed sequences of learning activities which form a hierarchical structure that can be modeled by means of Petri Nets. Learning content customization is a dynamic process supported by a set of standards-based data models. The...
In web service environment, B2B applications are usually built by composting pre-existing individual services, which are executed across multiple loosely-coupled autonomous organizations. The transactional challenges raised by the composition of services are twofold: relaxed atomicity and relaxed isolation. The relaxed atomicity of composite services can be verified at design stage. However, when...
Software as a service (SaaS) provides software application vendors a Web based delivery model to serve big amount of clients with multi-tenancy based infrastructure and application sharing architecture so as to get great benefit from the economy of scale. Though SaaS application is usually developed with highly standardized software functionalities to serve as many clients as possible, many clients...
Enterprises today face an increasing need to easily access and process knowledge they produce as well as automate their business processes. This need may be fulfilled by taking advantage of the Semantic Web and Semantic Web services technologies and implementing the concept of Semantic Business Process Management. In order to fulfil this vision, an enterprise and the specified part of the knowledge...
Several vulnerability analysis techniques in web-based applications detect and report on different types of vulnerabilities. However, no single technique provides a generic technology-independent handling of Web-based vulnerabilities. In this paper we present our experience with and experimental exemplification of using the application vulnerability description language (AVDL) to realize a unified...
Process modeling and rule modeling languages are both used to document organizational policies and procedures. However, little work has been done to understand their synergies and overlap. Understanding the relationship between the two modeling types would allow organizations to maximize synergies and reduce their modeling effort. In this paper we use the well-established Bunge-Wand-Weber (BWW) representation...
The consolidation of existing modeling, simulation, and analysis (MS&A) environments into a single object-oriented environment under the Air Force Integrated Collaborative Environment (AF-ICE) program has created a need for a framework to support cross domain interoperability for a heterogeneous mix of platforms and tools. The integrated information framework (I2F) was established to provide the...
The next generation Internet will be highly diversified in both underlying networking technologies and supported networking applications. The diversified Internet architecture requires effective collaboration among heterogeneous network domains to support various application requirements. One of the challenges to achieve this objective lies in enabling network domain collaboration and network-application...
