Over the last 25 years we have been able to automate the capture and delivery of product engineering decisions to an ever increasing extent, and in the last 15 years, we have begun to be able to automate some of the engineering activities themselves. In a similar way, we have been able to automate the capture and delivery of software engineering decisions for over 20 years, and we have automated the software engineering activities themselves. With this in mind, researchers at the National Institute of Standards and Technology (NIST) have undertaken a project-Automated Methods for Integrating Systems (AMIS)-to investigate whether we now have the technology to automate some of the manufacturing software integration processes. The objectives of the project are; to identify integration activities that may benefit from automation; to identify methods and technologies that may be brought to bear on automation of those activities; to characterize a set of common manufacturing integration problems that may be wholly or partly solved by automated means; to compare the cost of the automation with the cost of the point solutions, that is, to determine whether engineering for automated integration is easier, better, and/or more feasible than ad hoc engineering of the integrated system themselves.

There are significant issues regarding Large Scale System integration that are not being addressed in other forums such as current research portfolios or vendor user groups. Unfortunately, the issues in the area of large-scale system integration often fall into a netherworld; not research, not facilities, not procurement, not operations, not user services. Taken together, these issues along with the impact of sub-optimal integration technology means the time required to deploy, integrate and stabilize large scale system may consume up to 20 percent of the useful life of such systems. Improving the state of the art for large scale systems integration has potential to increase the scientific productivity of these systems. Sites have significant expertise, but there are no easy ways to leverage this expertise among them . Many issues inhibit the sharing of information, including available time and effort, as well as issues with sharing proprietary information. Vendors also benefit in the long run from the solutions to issues detected during site testing and integration. There is a great deal of enthusiasm for making large scale system integration a full-fledged partner along with the other major thrusts supported by funding agencies in the definition, design, and use of a petascale systems. Integration technology and issues should have a full seat at the table as petascale and exascale initiatives and programs are planned. The workshop attendees identified a wide range of issues and suggested paths forward. Pursuing these with funding opportunities and innovation offers the opportunity to dramatically improve the state of large scale system integration.

This thesis studies and analyzes the current Peruvian Air Force informationsystems with the view to implement an integrated network design for the existing computer based systems. The focus of this thesis is on examining the issues and factors that need to be taken into consideration for the integration design. The objective is to provide a feasible alternative for integration under the constraints of available resources and the limitations inherent to its environment. We believe that the implementation of the recommendations of this thesis will have a substantial impact on the information systems of the Peruvian Air Force, allowing new applications to be developed including a Decision Support System on the up-to-date data. It will also permit the resolution of many current problems related to data redundancy, inconsistency, and non-current data.

This report is an update of one issued in 1977 which predicted that the predicted death of analog circuitry (also called linear) would not occur; in fact, the patient appeared remarkably healthy. The report proved correct. We have the same situation again today: the same predictions and counter-prediction. Each year brings significant advances in the field of analog integrated circuitry. Many of the traditional arguments against analog circuitry are no longer valid. This report attempts to summarize what is available now, and what can (and cannot) be done with analog integrated circuits. It defines analog and makes some comparisons with digital. The most common types of analog integrated circuits are then listed and discussed. Lastly, some design and trouble-shooting hints are given, and the state-of-the-art is discussed. (Author)

This document presents a System Requirements Specification for an Integrated Corridor Management System (ICMS) in the I-15 Corridor in San Diego, California. The ICMS will consist of two major subsystems: the existing Intermodal Transportation Management Subsystem and a new, as-yet-undeveloped subsystem to be known as the Decision Support Subsystem. In addition, the ICMS will include organic functions such as Collect and Process Data, Access/Store Historical Data, System Management, and Lifecycle Support. Several existing and planned regional systems will be connected with the ICMS some of these will be upgrades to Intermodal Transportation Management System (IMTMS), some will be new systems. Section 2 provides an overview description of the I-15 ICMS , which includes the ICMS Context, ICMS Description, ICMS User Characteristics, System Constraints and Assumptions, and Dependencies. Section 3 includes a requirements framework, definitions of the I-15 ICMS components and key terms, action verb description, user needs developed in the I-15 Concept of Operations, an overview mind map of the IMCS requirements, and an indexed listing of the system requirements organized according to the ICMS's 17 functional areas. Appendix A provides Definitions, Acronyms, and Abbreviations Appendix B provides Requirements Management Metadata (for future requirements management activity). Appendix C includes U.S. Department of Transportation Comments on the Draft System Requirements Specification for the San Diego ICM Pioneer Site with SANDAG Responses.

The NASA Glenn (then Lewis) Research Center (GRC) led several expendable launch vehicle (ELV) projects from 1963 to 1998, most notably the Centaur upper stage. These major, comprehensive projects included system management, system development, integration (both payload and stage), and launch operations. The integration role that GRC pioneered was truly unique and highly successful. Its philosophy, scope, and content were not just invaluable to the missions and vehicles it supported, but also had significant Agency-wide benefits. An overview of the NASA Lewis Research Center (now the NASA Glenn Research Center) philosophy on ELV integration is provided, focusing on Atlas/Centaur, Titan/Centaur, and Shuttle/Centaur vehicles and programs. The necessity of having a stable, highly technically competent in-house staff is discussed. Significant depth of technical penetration of contractor work is another critical component. Functioning as a cohesive team was more than a concept: GRC senior management, NASA Headquarters, contractors, payload users, and all staff worked together. The scope, content, and history of launch vehicle integration at GRC are broadly discussed. Payload integration is compared to stage development integration in terms of engineering and organization. Finally, the transition from buying launch vehicles to buying launch services is discussed, and thoughts on future possibilities of employing the successful GRC experience in integrating ELV systems like Centaur are explored.

This document presents an analysis of Integrated Vehicle Based Safety Systems (IVBSS) for transit buses. The study took a three-pronged approach. The first was an analysis of the available IVBSS products, possible future products and the technologies. The second was a benefit-cost analysis of transit IVBSS. The third assessed the receptiveness among transit operators to use IVBSS products and the willingness of manufacturers to develop them. This study used the National Transit Database and crash data from 6 U.S. transit operators. The data show that there is an average of 1.5 collisions per transit bus and related annual costs of over $4,000. Of the technologies evaluated, only side object detection systems showed the potential to be cost effective. In general, transit agencies are receptive to in-vehicle safety devices when there is evidence of their effectiveness. Several vendors currently offer products while others are awaiting commitments from the U.S. DOT or coordinated transit industry interest before developing their products. It is recommended that the U.S. DOT pursue operational tests of the side object detection system and other stronger-performing systems in order to validate the findings of this study.
