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...
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...
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,...
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...
Enterprise architecture supports enterprise transformation through model-based holistic descriptions that capture and share the knowledge, concepts, and relationships representing the enterprise. Although enterprise architecture models portray the gap between the as-is and to-be enterprise, they disregard the underlying aspects that together enact enterprise transformation. This paper proposes an...
Requirements elicitation is a crucial activity and one of the first steps in software development process. A popular way to capture and describe requirements is through UML use case models. Transforming requirement specifications into software design models is a complex and error prone software development activity. Software design usually involves several models, each one representing a different...
In order to satisfy the increasing demand for electricity and to meet this demand with renewable energies, the present electrical grid has to adapt. The EU has already initiated measures to standardize and support a European Smart Grid development to facilitate communication amongst experts of different domains. Hence, this requires a mutual harmonization of terminologies as well as tools to strengthen...
The component-based business architecture integration of Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) systems is a popular research topic in the field of military operational research. Currently, the prevalent methodologies for business component integration tend to focus on software-level business component, and ignore enterprise concerns in business...
IT environments that consist of a very large number of rather small structures like microservices, Internet of Things (IoT) components, or mobility systems are emerging to support flexible and agile products and services in the age of digital transformation. Biological metaphors of living and adaptable ecosystems with service-oriented enterprise architectures provide the foundation for self-optimizing,...
Similar with definition of ‘service’, the term ‘service engineering’ (SE) can be broadly defined based on the context and the referring domain. This paper explores the evolutionary definition of SE, with later emphasis on IT/IS perspective. The paper begin with general definition of service and service engineering before elaborating IT perspectives on IT. A review on service orientation, Service Oriented...
Architectural component models represent high level designs and are frequently used as a central view of architectural descriptions of software systems. They play a crucial role in the whole development process and in achieving the desired software qualities. This paper presents an empirical study that examines the impact of hierarchies on the architecture-level software understand ability. In particular...
The construction of modern software projects with a multitude of quality requirements is a challenging and complex task particularly for large scale systems. Underestimating this complexity may result in project failures at worst or the delivery of poor quality products that are plagued with software defects at best. However, introducing scientific rigor at every step of the software development life...
Designing a software architecture requires a lot of effort. Functional and quality requirements need to be considered in relation to each other and balanced in order to define viable architectural abstractions that support them. Architects usually rely on their intuition and experience to create and choose between architecture alternatives. The viability of a decision can be checked by evaluating...
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...
In large organisations different stakeholders are usually responsible for the management of business processes. This paper addresses the situation where multiple stakeholders with different interests are handling parts of the same business processes. One technique to support this are process views where each stakeholder holds a personal view which can be executed or changed. In this paper we investigated...
Enterprise Architecture (EA) is a discipline designed to cope with the complexity of modern enterprises at the intersection of information technology and business operations. This article demonstrates how EA models can be enriched with the production function concept from microeconomics, enabling new and business relevant kinds of analysis. The approach is demonstrated through examples regarding growth...
Information Systems Development faces a lot of recurrent issues that must be addressed in every project. A lot of common requirements and features repeatedly appear on different projects challenging the development team. Exchanging solutions and the expertise gained over the evaluation of such solutions among projects can prevent the development teams from reinventing the wheel. The MDArte framework...
