This article presents a conceptual framework for systems integration in the area of computing systems. The framework identifies a hierarchical structure of concepts and methods that allows us to discuss the different elements of systems integration. The kernel of this approach is the concept of an integration architecture, specifying the general layout of the integration framework. Such an integration architecture is based on enabling technologies, like networking, and forms the basis for global integration activities. These global integration activities are targeted to preserve a common universe of discourse for the user of the integrated architecture and to agree upon a conceptual model of the application domain. Based on these prerequisites, two models for managing the process of systems integration, the post factor approach and the phased top-down approach, are discussed. 相似文献

Studies have indicated that when teachers believe technology uses are valuable, they are more likely to incorporate those uses into their practices. This hermeneutical phenomenology study investigated the value beliefs that underlie teachers’ uses of technology. To measure value beliefs, teachers’ uses (and reasons for those uses) of technology for teaching and learning were examined. Data were collected from eight award-winning teachers through an interview, observation, and electronic portfolio. Findings indicated that teachers used technology to address professional (e.g., creating customized classroom materials, improving classroom management by engaging students) and student needs (e.g., enhancing student comprehension, equipping students with technology skills), all of which related to the underlying value belief of promoting student learning. Based on these findings, professional development activities should emphasize the potential impact of specific technology uses on student learning. 相似文献

A design decomposition‐integration model, named COPE, is proposed in which Axiomatic Design Matrices (DM) map Functional Requirements to Design Parameters while Design Structure Matrices (DSM) provide structured representation of the system development context. In COPE, the DM and the DSM co‐evolve. Traversing between the two types of matrices allows for some control in the application of the system knowledge which surrounds the decision making process and the definition of the system architecture. It is argued that this approach describes better the design process of complex products which is constrained by the need to utilise existing manufacturing processes, to apply discrete technological innovations and to accommodate work‐share and supply chain agreements. Presented is an industrial case study which demonstrated the feasibility of the model. © 2004 Wiley Periodicals, Inc. Syst Eng 8: 29–40, 2005 相似文献

Abstract The course SDR: Sistemas de Representación(Systems of Representation), is the last stage of a line of work which has the objective of integrating information technologies in the education of architecture in a meaningful way. A distinctive mark of this pedagogic approach has been to look upon computer technology as an opportunity to rethink the methods, contents and goals of architecturaleducation,in thelight of contemporary culture. The course is structured in six themes, each one standing for a ‘system of representation’: ‘text’, ‘figure’, ‘object’, ‘image’, ‘space’ and ‘light’. Within every system, a variety of issues dealing with the concept of ‘representation’ are addressed in an interdisciplinary manner. It is a compulsory course lasting three semesters, in the second and third year of a five-year architectural program. It has been offered since the academic year 1999/2000. 相似文献

This article integrates an interoperability architecture, the OSCATM architecture, and a distributed transaction processing protocol, the X/Open® Distributed Transaction Processing model, into a unified model of large scale interoperability and distributed transaction processing. Applications supporting different business operations are often deployed in heterogeneous environments in which applications are stand alone islands and operations are fragmented. But in order to have integrated operations, a loosely coupled system of autonomous applications is required often bound together via a distributed transaction processing protocol. This article describes a model for this configuration. It will propose that the span of control of a transaction manager defines the transaction environment for a single application. Any two applications need not conform to the same supplier's transaction environment nor reside in the same environment. Interoperability must be provided among applications, since any one application cannot assume that any other application is under the control of the same transaction manager. Requirements are imposed upon the interactions of applications to support interoperability. The interface between transaction managers must be compatible with these requirements. Other distributed architecture standards must define the requirements for release independence, resource independence, accessibility transparency, location transparency, contract interfaces, and secure environment. 相似文献

复杂系统涌现与基于整体论的多智能体分析 总被引:1,自引:0,他引:1
研究复杂系统整体性,尤其整体性的涌现是现代科学技术研究的重要课题和难题。企图用多智能体的办法,甚至用自适应多智能体的办法来剖析系统的整体性,从系统方法学上来讲,显然是偏面的,不恰当的。本文从复杂系统整体性和涌现的基本概念出发,指出必须采用微观到宏观,再从宏观到微观相结合的整体论分析方法;提出了基于整体论的多智能体分析总体框架;通过系统整体性和涌现的区别与联系的探讨,又明确提出了在整体性分析中可采用数学、逻辑和实验(仿真)等三种不同的方法;最后,给出了适用于分析复杂系统整体性及其涌现的基于整体论的多智能体参考体系结构[1]。 相似文献

In a multidatabase system that consists of object databases, the same real-world entity can be stored as objects in different databases with incompatible object identifiers. How to identify and integrate these objects representing the same entities such that (a) object duplication in the query result can be avoided, (b) information for the entity can be gathered, and (c) the specialization of multiple classes can be built is an important issue to provide a well structured global object schema and a more informative query result. In this paper, we extend our results on probabilistic query processing and joining relations on incompatible keys to solve the problem. Various data and schema conflicts such as missing data, inconsistent data and domain mismatch which may exist in classes from different databases are considered in the process of identification.Recommended by: Amit Sheth 相似文献

In heterogeneous database systems,partial values have been used to resolve some schema integration problems. Performing operations on partial values may producemaybe tuples in the query result which cannot be compared. Thus, users have no way to distinguish which maybe tuple is the most possible answer. In this paper, the concept of partial values is generalized toprobabilistic partial values. We propose an approach to resolve the schema integration problems using probabilistic partial values and develop a full set of extended relational operators for manipulating relations containing probabilistic partial values. With this approach, the uncertain answer tuples of a query are associated with degrees of uncertainty (represented by probabilities). That provides users a comparison among maybe tuples and a better understanding on the query results. Besides, extended selection and join are generalized to -selection and -join, respectively, which can be used to filter out maybe tuples with low probabilities — those which have probabilities smaller than . 相似文献

A mathematically advanced method for improving the fidelity of cost estimation for an engineering system is presented. In this method historical cost records can be expanded either through the use of local metamodels or by using an engineering build‐up model. In either case, the expanded data set is analyzed using principal component analysis (PCA) in order to identify the physical parameters, and the principal components (PCs) which demonstrate the highest correlation to the cost. A set of predictor variables, composed of the physical parameters and of the multipliers of the principal components which demonstrate the highest correlation to the cost, is developed. This new set of predictor variables is regressed, using the Kriging method, thus creating a cost estimation model with a high level of predictive capability and fidelity. The new methodology is used for analyzing a set of cost data available in the literature, and the new cost model is compared to results from a neural network based analysis and to a cost regression model. Further, a case study addressing the fabrication of a submarine pressure hull is developed in order to illustrate the new method. The results from the final regression model are presented and compared to results from other cost regression methods. The technical characteristics of the new novel general method are presented and discussed. © 2011 Wiley Periodicals, Inc. Syst Eng 相似文献

The issue of information architecture (IA) for organizations has recently received considerable attention in IS development. However, as yet little research has been reported on modeling IA using a systematic approach. This paper describes an object-oriented method for modeling it. The proposed method extends the traditional concept of IS analysis into the context of contemporary information technology (IT), and is useful for planning IT-enabled business process reengineering for the organization. 相似文献

As systems continue to grow in scale and complexity, systems integration (SI) has become a key concern. This is especially the case in defense and aerospace. SI involves interfacing and enabling the interactions of component elements to collectively provide the functionality needed by the system to accomplish its goals. SI is part of the overall system development life cycle. SI increases in complexity when there are legacy systems that need to be integrated, and when humans are an integral part of the system. An added layer of complexity is introduced when the system has to exhibit resilience and adaptability in the face of contingencies in the operational environment. This paper addresses key perspectives and challenges in SI. Specifically, it presents the integration continuum, ranging from loose to tight integration. It presents a SI ontology that captures the key issues and concerns in a standard language. It also presents various categories of integration and their unique challenges. This paper is intended to clarify various types of integration and to stimulate new ways of thinking about SI. 相似文献
