Software Integration

La représentation des données techniques, leur échange voire leur partage entre acteurs du processus de construction, tout au long du cycle de vie du bâtiment, constituent des objectifs importants pour tous les intervenants de l'acte de bâtir. L'avènement de logiciels de métiers sophistiqués a transformé dans une certaine mesure les pratiques professionnelles, l'ensemble des tâches depuis la conception jusqu'à la gestion de patrimoine ayant recours à l'informatique pour représenter et manipuler les informations sur les projets. Cependant, loin de faciliter la communication de ces données, les outils de CAO et les logiciels spécialisés ont le plus souvent mis en avant des solutions propriétaires incompatibles. La maquette électronique, à l'instar de ce que d'autres secteurs utilisent déjà (e.g. aéronautique, automobile), au plus grand bénéfice du maître d'ouvrage n'est pas encore une réalité dans le secteur du BTP. néanmoins, les travaux récents conduits dans le cadre de projets européens ou de normes internationales comme STEP laissent augurer l'avènement de solutions informatiques ouvertes qui feront de cette maquette une réalité.

This paper shows one possible way to enhance power system software integration by combining RESTful Web services (RESTful WS) and the IEC 61970 set of standards. We also discuss the differences between SOAP and RESTful Web services in the context of this research. We propose a Web service, which wraps the resource oriented power system data model defined in the IEC 61970-301 Common Information Model (CIM) and the generic query interface defined in IEC 61970-403 Generic Data Access (GDA). We will demonstrate that a RESTful WS atop of existing IEC 61970 standards can significantly loose the couplings between different software packages used in power system control centers. We have performed tests on real life power system data models (some used in CIM interoperability tests) to make the tests more realistic. The proposal depicted in this paper provides another powerful tool for creating truly distributed power system software solutions.

Various application domains require the integration of distributed real-time or near-real-time systems with non-real-time systems. Smart cities, smart homes, ambient intelligent systems, or network-centric defense systems are among these application domains. Data Distribution Service (DDS) is a communication mechanism based on Data-Centric Publish-Subscribe (DCPS) model. It is used for distributed systems with real-time operational constraints. Java Message Service (JMS) is a messaging standard for enterprise systems using Service Oriented Architecture (SOA) for non-real-time operations. JMS allows Java programs to exchange messages in a loosely coupled fashion. JMS also supports sending and receiving messages using a messaging queue and a publish-subscribe interface. In this article, we propose an architecture enabling the automated integration of distributed real-time and non-real-time systems. We test our proposed architecture using a distributed Command, Control, Communications, Computers, and Intelligence (C4I) system. The system has DDS-based real-time Combat Management System components deployed to naval warships, and SOA-based non-real-time Command and Control components used at headquarters. The proposed solution enables the exchange of data between these two systems efficiently. We compare the proposed solution with a similar study. Our solution is superior in terms of automation support, ease of implementation, scalability, and performance.

Software integration is a crucial aspect of collaborative software applications and systems. It enables a number of different software applications, created by different developers, using different programming languages, and even located at different places to work with each other collaboratively to achieve common goals. Nowadays, a number of techniques are available to enable software integration. Messaging is the most prominent technique in this respect. In this paper, two leading open-source messaging brokers, Apache ActiveMQ and Apache Apollo, have been experimentally compared with each other with regard to their messaging capabilities (message sending and receiving throughputs). Both brokers support exchanging messages between heterogeneous and distributed software applications using several messaging mechanisms including Java Message Service (henceforth JMS). A number of experimental test scenarios have been conducted to obtain the comparison results that indicate the one-to-one JMS messaging performance of each broker. Overall performance evaluation and analysis showed that Apache Apollo outperformed Apache ActiveMQ in all test scenarios regarding message sending throughputs. Whereas, Apache ActiveMQ outperformed Apache Apollo in most test scenarios regarding message receiving throughputs. Moreover, the evaluation methodology (test conditions, test scenarios, and test metrics) proposed in this paper has been carefully chosen to be adopted by software developers to evaluate other messaging brokers to determine the acceptable level of messaging capabilities in distributed environments of heterogeneous software applications.

Software integration has been a solution to the problem of connecting dissimilar systems for many years. Integration is still a challenging issue. EAI is defined as the process of integrating enterprise systems with existing applications. Since software integration research has yielded a variety of different concepts, we survey and discuss this terminology. EAI arises as an evolution of the CASE

Abstract The aim of this study is to investigate the benefits of pitch insulation and ceiling insulation for air-conditioned buildings in the tropical climate of Malaysia. These are performed via computer simulations using a whole-building thermal energy software ...

BIM stands for Building Information Model. The idea of BIM-based CAD is not new: it has always been foreseen as the ideal way to represent buildings digitally, but it has never been mainstream for commercial products until recently. The building industry has traditionally communicated building construction information through drawings with notes and specifications. CAD technology automated that process. However, cost

When initiating a training course, an instructor is faced with the complex task of retrieving the appropriate exercises and building the relevant sequence (a teaching module) to help the trainees gradually acquire a given skill, either as individuals or as a team. Retrieval of an exercise is a complex task because most of the useful selection criteria (e.g. the teaching goals) do not explicitly appear as part of the data set that makes up the exercise. Available exercise data mainly refer to parameter values that the simulation software will further manipulate in real- time. Furthermore, lack of information about the exercise complexity level makes it difficult to arrange exercises in a structured sequence. The availability of a set of training aids that will enable a population of instructors to characterize existing exercises and further extract structured teaching modules therefore represents a significant step forward compared to today's instructional environments.
