A multi-INT semantic reasoning framework for intelligence analysis support

Lockheed Martin Corp. has funded research to generate a framework and methodology for developing semantic reasoning applications to support the discipline oflntelligence Analysis. This chapter outlines that framework, discusses how it may be used to advance the information sharing and integrated analytic needs of the Intelligence Community, and suggests a system I software architecture for such applications

The Critical Need for Software Architecture Practices in Software Development Process

Software architecture is the master plan of every reliable software system. It is the building block of any kind of software system which greatly determines the success of the system. This paper argues that every system needs a good architecture and that requires the use of good architecture engineering practices in a software development process. The paper recognized software architecture practice as a discipline pervading all phases of software development and then identifies some of the pertinent areas where architectural practice can be used based on a framework. In addition a model showing how software architecture fits into the phases of a generic software development process lifecycle was presented. The model is to enable software developers and acquirers to use effective software architecture practices during software development in order to exert significantly greater control over software product qualities.

Software architecture analysis tool : software architecture metrics collection

The Software Engineering discipline lacks the ability to evaluate software architectures. Here we describe a tool for software architecture analysis that is based on metrics. Metrics can be used to detect possible problems and bottlenecks in software architectures. Even though metrics do not give a complete evaluation of software architectures it is a useful analysis method. The Software Architecture Analysis tool can be applied to XMI output generated by a UML modelling tool. We have done this using Rational Rose

A domain specific software model for interior architectural education and practice

Cataloged from PDF version of article.Interior architectural education and practice employ various general-purpose software packages. This study problematizes that as none of these packages is developed specifically for interior architectural design process and purposes, both interior architecture education and market seek ways to fulfill their specific needs. It is argued that currently interior architecture does not fully benefit from digital opportunities. A specific software package for interior architecture will enable the discipline to put forth its assets and manifest its existence. Consequently, this study proposes a domain specific model for interior architectural software. Initially, general-purpose and domain specific computer aided architectural design (CAAD) software used in interior architecture are determined. Then, selected software packages are analyzed according to Szalapaj's Ill set of features: 'drawing'. 'transformation', 'view', 'rendering' and 'other'. Based on these analyses. domain specific requirements for interior architecture are obtained. Consequently, questionnaires and interviews are performed with interior architectural students and professionals in order to determine the user needs. Finally, based on the findings, a software model for interior architecture is proposed. (C) 2011 Elsevier B.V. All rights reserved

Computer-Aided Warehouse Engineering (CAWE): Leveraging MDA and ADM for the Development of Data Warehouses

During the last decade, data warehousing has reached a high maturity and is a well-accepted technology in decision support systems. Nevertheless, development and maintenance are still tedious tasks since the systems grow over time and complex architectures have been established. The paper at hand adopts the concepts of Model Driven Architecture (MDA) and Architecture Driven Modernization (ADM) taken from the software engineering discipline to the data warehousing discipline. We show the works already available, outline further research directions and give hints for implementation of Computer-Aided Warehouse Engineering systems

Domain specific software design for decision aiding

McDonnell Aircraft Company (MCAIR) is involved in many large multi-discipline design and development efforts of tactical aircraft. These involve a number of design disciplines that must be coordinated to produce an integrated design and a successful product. Our interpretation of a domain specific software design (DSSD) is that of a representation or framework that is specialized to support a limited problem domain. A DSSD is an abstract software design that is shaped by the problem characteristics. This parallels the theme of object-oriented analysis and design of letting the problem model directly drive the design. The DSSD concept extends the notion of software reusability to include representations or frameworks. It supports the entire software life cycle and specifically leads to improved prototyping capability, supports system integration, and promotes reuse of software designs and supporting frameworks. The example presented in this paper is the task network architecture or design which was developed for the MCAIR Pilot's Associate program. The task network concept supported both module development and system integration within the domain of operator decision aiding. It is presented as an instance where a software design exhibited many of the attributes associated with DSSD concept

Rapid Prototyping of Domain-Specific Architecture Languages

International audienceSoftware architecture has become a sensitive discipline, which consists in concretizing the user requirements into a set of artifacts that can be used to model and reason about the software to be developed. However, the architect often relies on its own knowledge to map domain-specific requirements onto generic software abstractions. Most of the time, this leads to the definition of repetitive tasks and architecture fragments, which can be particularly error prone. We therefore believe that architects need a more flexible approach to cope with the definition of domain-specific architectures by leveraging general purpose architecture description languages. This paper introduces the FraSCAla framework as an architectural framework that can be used to rapidly prototype and experiment domain-specific ADLs in order to catalyze the definition and to improve the reliability of software architectures. We demonstrate the merits of this approach on two case studies that illustrate component-based architectures exhibiting various categories of architectural patterns

A Generic Software Architecture For Prognostics

Prognostics is a systems engineering discipline focused on predicting end-of-life of components and systems. As a relatively new and emerging technology, there are few fielded implementations of prognostics, due in part to practitioners perceiving a large hurdle in developing the models, algorithms, architecture, and integration pieces. As a result, no open software frameworks for applying prognostics currently exist. This paper introduces the Generic Software Architecture for Prognostics (GSAP), an open-source, cross-platform, object-oriented software framework and support library for creating prognostics applications. GSAP was designed to make prognostics more accessible and enable faster adoption and implementation by industry, by reducing the effort and investment required to develop, test, and deploy prognostics. This paper describes the requirements, design, and testing of GSAP. Additionally, a detailed case study involving battery prognostics demonstrates its use
