System design is an important phase of system engineering, determining system architecture to satisfy specific requirements. System design focuses on analyzing performance requirements, system modeling and prototyping, defining and optimizing system architecture, and studying system design tradeoffs and risks. Modern enterprise information systems (EIS) are distributed systems usually built on ...

In enterprise architecture, the goal is to integrate business resources and IT resources in order to improve an enterprise’s competitiveness. In an enterprise architecture project, the development team constructs a hierarchical model that represents the enterprise. Our goal is to develop a hierarchical object-oriented model that can serve as enterprise model. The state of the art in hierarchica...

The paradigm of Interoperability Service Utility (ISU) is considered as one of the grand challenges in research of Enterprise Interoperability. In this paper, we discuss on the relevance and impact of the current ISU research to the semantic interoperability in general and propose an original architecture for implementation of the Semantic Interoperability Service Utilities (S-ISU). The propose...

Enterprise Architecture (EA) management seeks to mutually align business and IT while fostering flexibility to react upon environment changes appropriately. Highly distributed data within the entire enterprise is collected to facilitate decision making processes during enterprise transformations. At the same time enterprise architects and EA stakeholders have new and arising questions hard to p...

Challenges that are hardly technical, have been reported to occur during enterprise architecture development. To address those caused by ineffective collaboration between architects and organisation stakeholders, we are developing a method referred to as Collaborative Evaluation of Enterprise Architecture Design Alternatives (CEADA). Our method aims at enabling effective execution of collaborat...

Due to the ISO9001:2000 requirement for modelling business processes and the need to share business process models in Enterprise Networks, many enterprises will be looking at sharing and reusing existing enterprise models. This article identifies measures to ensure that enterprise models are interpreted as intended, thereby controlling the quality of processes using and reusing enterprise model...

Enterprise architecture management requires an extensive amount of information which concern distinct domains like company strategy, business processes, and IT-systems. To support management with essential information enterprise architecture models are reckoned almost indispensable. However, the creation and maintenance of an encompassing enterprise architecture model has proven to be a challen...

Enterprise architecture is gaining acceptance as an approach to manage change and foster IT/business alignment by (1) propagating strategy and process changes to the software and infrastructure level, by (2) supporting consistent business transformation enabled by technology innovations, and by (3) decoupling business-oriented and technology-oriented architectures. Due to constant change in bus...

To satisfy new market requirements, manufacturing industry has shifted from mass production that takes advantage of the scale of production, to quality management that optimizes the internal enterprise functions, to e-manufacturing era that leverage intellectual capital via collaborative innovation. In the same time, the product itself is becoming the most important asset for sustainable busine...

It is generally accepted that security requirements have to be identified as early as possible to avoid later rework in the systems development process. However, in practice quite often security aspects are considered either at the later stages of development cycles (increments in agile projects) or addressed only when problems arise. One of the reasons for difficulties of early detection of se...
