Quantitative Analysis of Enterprise Architectures

Abstract

Abstract. Enterprise architecture is concerned with a description of all the relevant elements that make up an enterprise and how these elements inter-relate. It covers aspects ranging from the technical infrastructure, through software applications, to business processes and products. The relations between these layers play a central role. Also from a quantitative analysis perspective, the layers are interrelated: the higher layers impose a workload on the lower layers, while the performance characteristics of the lower layers directly influence the performance of the higher layers. This paper presents an approach for quantitative analysis of layered, service-based enterprise architecture models, which consists of two phases: a 'top-down' propagation of workload parameters, and a 'bottom-up' propagation of performance or cost measures. By means of an example we demonstrate the application of the approach, and show that a seamless integration with other performance analysis methods (e.g., queueing analysis) can be achieved.

A new Approach towards Cost and Benefit Enterprise Architecture Analysis

“…from the studies methods, the one presented by Yu and associates [7], incompletely and in elementary forms, the one introduced by Jacob and Jonkers [8], the one presented by KHayyami [3], the one provided by Razavi [2] and also the ones presented by researcher group of KTH university of sweden [9] 3. In Neimann [6], cost and benefit of enterprise efficiency are studied abstract .…”

Development of an approach to analysis and optimization of data flow diagrams

“…Согласно результатам исследования архитекту-ры предприятия [21], неравномерность загрузки эле-ментов бизнес-архитектуры (внешние сущности и ра-боты на диаграмме DFD) и архитектуры приложений и данных (накопители данных на диаграмме DFD) явля-ется причиной снижения производительности модели-руемой системы. Таким образом, выявление неравно-мерности в загрузке элементов позволяет определить «узкие места» моделируемой системы [22].…”

An Approach towards Enterprise Architecture Analysis using AHP and Fuzzy AHP

“…The analysis methods in the EA community including [2] [15], [16], [17], [18], [19], [20], [21], [22], [23], [24]. The main contributions of our approach which make it different from the approaches of group 2 are as below: a) In our approach, the criteria and sub-criteria of a quality attribute are given different weights according to the EA layers each of them belong to and also the importance of each EA layer in the enterprise.…”
