We focus on dynamic model usability and utility, performed throughout system engineering. The dynamic model is designed in relation to the system use scenarios. We generate then automatically the static models (data model, component model) from the dynamic one. A dynamic functional modeling based method is proposed to generate automatically the static and the dynamic organic architecture of a system...
To overcome the current cybersecurity challenges of protecting our cyberspace and applications, we present an innovative cloud-based architecture to offer resilient Dynamic Data Driven Application Systems (DDDAS) as a cloud service that we refer to as resilient DDDAS as a Service (rDaaS). This architecture integrates Service Oriented Architecture (SOA) and DDDAS paradigms to offer the next generation...
The development of service computing technology has triggered the need for organizations to build a service computing system. This system is able to deliver IT services that can meet the challenges and needs of business services. An understanding of the service computing systems engineering life cycle is necessary to model and build the systems. This paper conducts the study of the service computing...
This work presents a preliminary proposal of a simple architecture for the development of heterogeneous applications, in order to allow the interoperability of applications in digital TV, mobile and web, for its incorporation in IoT. An MDA-based architecture is presented to develop applications based on a high-level abstraction, for which a brief review of MDA concepts and the state of the art is...
The use of services computing technology provides support to the development of modern services industries. Services computing utilizes and implements computing technology to develop IT services systems that are capable of supporting and developing services innovation. This condition motivates the organization to be able to present the services computing systems in the form of IT services systems...
Nowadays, cloud computing is hard to effectively sustain the implementation of the commercial model of Internet Service globalization. There is a growing trend to build an environment of cloud service, with the capacity to serve anytime and anywhere, by mutual cooperation between cloud service providers around the world. However, this tendency will raise a key issue which is how to provide a benign...
Recent developments in computing and networking are making it possible for a customer to benefit from the products of computing without the full investment in hardware, software, personnel and infrastructure. This is the main idea behind cloud computing. In this case, hardware, software and expert personnel can be centrally located and the “services” they provide are accessed over the network. This...
In the emerging cloud computing and services computing era, technology advancements enable the sharing of unlimited resources, the usage of services without ownership, and composition of services on demand. Besides these desired features of IT services provisioning, system reliability, data security, user's privacy are also highly concerned on the cloud. This paper aims to analyse the reengineering...
For the recent advances of Cloud Computing technologies, cloud applications have been popularity for their rich set of features. Therefore, their practical use for promoting business values can be expected. As such, cloud applications are recognized as a trend for the next generation of existing Web applications, and hence how to migrate these Web applications to the clouds becomes a desired field...
This study presents the Architecture Specific Model (ASM) defined by the MoWebA approach to improve the development of web applications for different architectures. MoWebA is a model-driven approach to web applications development. The article presents a general overview of MoWebA, including the methodological aspects related to its modeling and transformation processes, the process of defining the...
Time-critical aerospace applications demand more and more large engineering teams. It also includes manufacturing fragmentation across geographically-dispersed locations. The integration required is usually for tightly-coupled hardware-software components/subsystems. Early system verifications/validation based on remote integration can significantly reduce costs and risks since tests can be remotely...
A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, small embedded devices are used to monitor and manage the physical process. Because of these physical devices with limited resources, it is impossible to perform complex calculations and processing. In view of this situation, we apply Service-oriented Architecture (SOA) concepts to CPS, called a...
In the last few years, we witnessed a growing interest in interoperability and portability topics within the Cloud Computing area. In fact, most heterogeneous PaaS solutions have been developed with no standard APIs, and with different models and levels of service; in this scenario, vendor lock-in becomes an issue. Cloud4SOA project aims to design and develop a Reference Architecture that could solve...
Nowadays, QoS parameters are more and more integrated in composite web service architectures. The performance evaluation of the latter is becoming a challenging issue, as it demands to satisfy complex synchronization as well as different requirements. We investigate in this paper the use of Time Petri Nets (TPN) for modeling and analyzing the behavior of such architectures in the aim to compute the...
This work is based on two major areas, the Multiview Service Oriented Architecture and the combination between the computing cloud and MVSOA. Thus, it is suggested to extend firstly the service oriented architecture (SOA) into an architecture called MVSOA by adding two components, the Multiview service generator, whose role is to transform the classic service into Multiview service, and the data base,...
The large computational and storage capabilities of a cloud platform offer challenging opportunities to address advanced process control techniques and algorithms. This paper presents a cloud framework for a library of advanced control sequences and algorithms. This library can be used for online or offline model identification. The work presents the basic concepts of cloud computing and how they...
We present a novel technique for static slicing of SoaML Service Interface Diagram. In this technique, a Service Interface Diagram is converted into an intermediate representation which we have named as Service Interface Dependency Graph(SIDG). The SIDG identifies Service Call Dependency and Composite Dependency from Service Interface Diagram. Giving slicing criterion as input, our aglorithm traverses...
SmartLife ecosystems are emerging as intelligent user-centered systems that will shape future trends in technology and communication. Biological metaphors of living adaptable ecosystems provide the logical foundation for self-optimizing and self-healing run-time environments for intelligent adaptable business services and related information systems with service-oriented enterprise architectures....
Service selection is an important concept in service oriented architectures that enables the dynamic binding of services based on functional and non-functional requirements. The introduction of the concept of on-demand provisioned services significantly changes the nature of services and as a consequence the traditional service selection process does not fit anymore. Existing approaches for service...
Integration of hospital information systems (HIS) is an important area and one the basic requirements of hospitals since it increases quality of care and at the same time reduces costs of creating, upgrading, updating and keeping up with technology and healthcare industry standards and information technology. Cloud computing with features like multitenancy, massive scalability, elasticity, pay as...
