Decoding the architectural theory

Starting from the illustration of the definition and concept of the architectural theory, the author established his unique understanding about the framework of the architectural theory and the innovation of the architectural theory underlined by Chinese characteristics.

Case Study of Service Oriented Enterprise Architecture Framework

Many organizations have now adopted Service Oriented Architecture （SOA） as an architectural style to help them with architecture, design and implementation of their core services and systems. Most of these organizations are challenged in integrating SOA style with their overall Enterprise Architecture work. This framework links an SOA style with the Enterprise Architecture （EA） methodologies to help organizations organize their SOA effort as a key part of their Enterprise Architecture. The case study demonstrates the implementation of architecture goal with organization vision in service oriented organizational structure using services that align Business with Technology. The framework is validated and has reserved the privileges of SOA and EA.

An approach to measuring business-IT alignment maturity via DoDAF2.0

Measuring the business-IT alignment(BITA)of an organization determines its alignment level,provides directions for further improvements,and consequently promotes the organizational performances.Due to the capabilities of enterprise architecture(EA)in interrelating different business/IT viewpoints and elements,the development of EA is superior to support BITA measurement.Extant BITA measurement literature is sparse when it concerns EA.The literature tends to explain how EA viewpoints or models correlate with BITA,without discussing where to collect and integrate EA data.To address this gap,this paper attempts to propose a specific BITA measurement process through associating a BITA maturity model with a famous EA framework:DoD Architectural Framework 2.0(DoDAF2.0).The BITA metrics in the maturity model are connected to the meta-models and models of DoDAF2.0.An illustrative ArchiSurance case is conducted to explain the measurement process.Systematically,this paper explores the process of BITA measurement from the viewpoint of EA,which helps to collect the measurement data in an organized way and analyzes the BITA level in the phase of architecture development.

ARCHITECTURE AND ITS IMPLEMENTATION FOR ROBOTS TO NAVIGATE IN UNKNOWN INDOOR ENVIRONMENTS

It is discussed with the design and implementation of an architecture for a mobile robot to navigate in dynamic and anknown indoor environments. The architecture is based on the framework of Open Robot Control Software at KTH （OROCOS@KTH）, which is also discussed and evaluated to navigate indoor efficiently, a new algorithm named door-like-exit detection is proposed which employs 2D feature oft. door and extracts key points of pathway from the raw data of a laser scanner. As a hybrid architecture, it is decomposed into several basic components which can be classified as either deliberative or reactive. Each component can concurrently execute and communicate with another. It is expansible and transferable and its components are reusable.

EAFoC： Enterprise Architecture Framework Based on Commonality

The recent rapid development in information systems （ISs） has resulted in a critical need for integration and interoperability between heterogeneous ISs in various domains, using specific commonalities. However, stovepipe systems have been caused due to inconsistencies in planning IS architecture among stakeholders. So far, there has been no research on an enterprise architecture framework （EAF） that can satisfy with the coefficient factors of system architecture （SA） and enterprise architecture （EA）. This paper proposes a new EAF that can resolve the problems inherent in existing legacy EAFs and their features. EAFoC （Enterprise Architecture Framework based on Commonality） is based on commonality that can be satisfied as the coefficient factors in both SA and EA within a common information technology （IT） domain. Thus, it should be possible to integrate an established heterogeneous framework for each stakeholder＇s view. Consequently, the most important contribution of this paper is to establish the appropriate EAFoC for the development of consistent IS architecture, smooth communication among stakeholders, systematic integration management of diversified and complicated new IT technologies, interoperability among heterogeneous ISs, and reusability based on commonality with other platforms.

ADVANCES IN DECISION ANALYSIS AND SYSTEMS ENGINEERING FOR MANAGING LARGE-SCALE ENTERPRISES IN A VOLATILE WORLD: INTEGRATING BENEFITS, OPPORTUNITIES, COSTS AND RISKS (BOCR) WITH THE BUSINESS MOTIVATION MODEL (BMM)

Over the past few decades, innovations in Information and Communication Technologies （ICT） have led to a significant increase in the complexity of enterprise information systems. This has led to new challenges for enterprise architects, systems engineers, business managers and other decision makers who must cope with the complexity of business plans and processes （particularly automated engineering processes）. In order to better manage this complexity, the Business Rule Group （BRG） has put forth the Business Motivation Model （BMM）. The original BMM uses a SWOT （Strength, Weakness, Opportunity, and Threat） decision analysis approach. However, the SWOT framework contains significant limitations with respect to decision making and ICT risks, hampering the decision making ability of enterprise architects, business managers, engineers, and other decision makers. The AHP （Analytic Hierarchy Process） and ANP （Analytic Network Process） are among the most widely used decision making tools： they commonly implement a Benefit - Opportunity - Cost - Risk （BOCR） analysis to improve the effectiveness of business decision making. A new approach is put forth that replaces the original SWOT assessment with an ANP-based BOCR analysis. As well, the original BMM is modified and applied in a Component Architecture Framework （CAF）.
