As more commercial services are offered and provided on-line, tools to analyse their socio-economic impact are also needed. For instance, new services such as Spotify, Uber and AirBnB have been able to disrupt different sectors because they rely on combining new business models together with information and communication technology (ICT). For (traditional) enterprises, however, launching that kind...
Automatic localization of services at the time of logical modeling is a difficult task. This is because of the complexity of models and the scattered nature of enterprise architecture information in organizations, systems as well as actors and applications. However, all information about logical services is described in the eLEL and in the aspects of the business architecture of the Praxeme methodology...
This paper briefly introduces the Command Query Responsibility Segregation (CQRS) and discusses the performance of the architecture. The pattern is separated from the business by modifying the behavior of modifying (adding, deleting, modifying the system state) and querying (without modifying the system state), making the logic clearer and easier to target different parts Optimization, and finally...
The increasing complexity of modern Large-Scale systems and System-of-Systems (SoSs) makes their design and development extremely challenging. To face this difficulty new Modeling and Simulation techniques, methods, and tools are emerging and some of them take advantage of distributed simulation environments. In this context, the IEEE 1516-2010 - High Level Architecture (HLA) is a well-known and accepted...
Earlier research has identified network analysis techniques, methods, and models used to analyze structural aspects of an enterprise architecture (EA) modeled as a network or graph. However, there is still no common set of conceptual elements for such research that could allow one to identify the information requirements needed to perform this type of analysis. In the present research, we organize...
Digitization fosters the development of IT environments with many rather small structures, like Internet of Things (IoT), Microservices, or mobility systems. They are needed to support flexible and agile digitized products and services. The goal is to create service-oriented enterprise architectures (EA) that are self-optimizing and resilient. The present research paper investigates methods for decision-making...
Despite the great benefits of cloud computing on businesses, some organizations have had to withdraw from its service due to incomplete compliance to conditions from standards, bodies, or Service Level Agreements which have led to their being penalized. A structured and efficient model is helpful to aid small and medium scale enterprises (SMSEs) utilize cloud services safely and ascertain their fitting...
Research data repositories are necessary infrastructures that ensure the data generated for research are accessible, stable, reliable, and reusable. Based on years of accumulated data work experience, the Computer Network Information Center of the Chinese Academy of Sciences has built a multi-disciplinary data repository ScienceDB for research users and teams using its big data storage, analysis and...
Collaboration in business environments is an ongoing trend that is enabled by and based on cloud computing. It supports flexible and ad-hoc reconfiguration and integration of different services, which are provided and used via the internet, and implemented within business processes. This is an important competitive advantage for the participating stakeholders. However, trust, policy compliance, and...
Looking at the end-to-end processing, typical software-intensive systems are built as a system-of-systems where each sub-system specializes according to both the business and technology perspective. One challenge is the integration of all systems into a single system — crossing technological and organizational boundaries as well as functional domains. To facilitate the successful integration we propose...
The paper proposes a methodology for the development of a marketing decision support system using Big Data technology and data mining techniques. The approach was inspired by the CRISP-DM methodology, which is not oriented towards Big Data projects. Therefore, we have modified this methodology with respect to the purpose and technological requirements of the project. The proposed methodology was tested...
System specifications can be modeled using various types of notations and diagrams regarding applications of the particular model. In this paper, we present an overview of the existing solutions, focusing on UML, BPMN and DMN models and the diagrams provided by these notations. We perform a comparison of these approaches and provide examples of representing system requirements in these notations.
This paper presents a new approach for identifying unknown and/or unwanted states within a system of systems (SoS) architecture using a graphical representation of the event-based modeling language, Monterey Phoenix. The paper demonstrates how the graphical modeling tool can create a single model that contains a mix of human, system, and environmental events, all of which contain event attributes...
Cloud based technology heavily changed the way how Enterprise Resource Planning (ERP) systems are handled through the whole lifecycle. The previous release-by-release driven by main version change (from pre-alpha to gold release) was developed into a continuous release management. Business processes although remained the same, but how can be determined, which part of the software needs to remain untouched,...
Microservices architectures are a departure from traditional Service Oriented Architecture (SOA). Influenced by Domain Driven Design (DDD), microservices architectures aim to help business analysts and enterprise architects develop scalable applications that embody flexibility for new functionalities as businesses develop, such as scenarios in the Internet of Things (IoT) domain. This article compares...
Teaching software architecture to undergraduate students is particularly hard because they typically have no experience with medium or large systems with competing stakeholders. A particularly hard case is ATAM (Architecture Trade-off Analysis Method), which allows the evaluation of architectural designs and quality attributes by competing stakeholders. This article describes ATAM-RPG, a role-playing...
The rapid development of intelligent terminals and mobile Internet industry has brought many challenges and opportunities to the mobile network. Mobile Network Open Services can provide users and developers with the open resources consisted of network infrastructure, network data and diversified services, so as to build an open, flexible, collaborative Internet ecosystem. The ability to open the mobile...
Industry 4.0 is opening new avenues for reconfigurable and information-centric integration of enterprise functions and control systems. Most of the current approaches (e.g., ISA-95) view enterprise architectures in a pre-defined, monolithic, and hierarchical sense. To enable more innovative, personalized, and efficient manufacturing processes, however, such ‘tree-like’ architectures must turn into...
This publication presents a novel concept for autonomous and decentralised M2M application service provision. The functional architecture of the approach is introduced as well as a detailed description of the system structure and process for application creation. Furthermore, this publication describes details about the proposed process for decentralised M2M application service management and formal...
Energy interconnection (EI) is a logical consequence when ideas of open source and distributed scheme from the information field are introduced into the energy field. EI is essentially a typical cyber-physical system. This paper studies the new capabilities in sensing, computation, communication and control by analyzing its characteristics and demand. Firstly, we analyze the system architecture of...
