 pdf fileSystem Engineering Process Overview
Introduction This document provides a high level look at the Systems Engineering Process for ITS projects. More detailed information of the System Engineering process is available through FHWA’s publication, “System Engineering for Intelligent Transportation Systems”. The systems engineering should be viewed as an extension to the traditional project development process that is already established in the department. As the NDDOT gains experience with ITS projects and the systems engineering approach, we will find that we can weave the systems engineering processes and best practices into our overall project development process.

 pdf fileNASA Systems Engineering Handbook
This handbook was written to bring the fundamental concepts and techniques of systems engineering to NASA personnel in a way that recognizes the nature of NASA systems and the NASA environment. The authors readily acknowledge that this goal will not be easily realized. One reason is that not everyone agrees on what systems engineering is, nor on how to do it. There are legitimate differences of opinion on basic definitions, content, and techniques. Systems engineering itself is a broad subject, with many different aspects. This initial handbook does not (and cannot)

 pdf fileA Life Cycle Cost Summary
SUMMARY: Life cycle costs (LCC) are cradle to grave costs summarized as an economics model of evaluating alternatives for equipment and projects. Engineering details drive LCC cost numbers for the economic calculations. The economics of proposals drives the scenario selection process. Good engineering proposals without economic justification are often uneconomical. Good engineering with good economics provide business successes. The LCC economic model provides better assessment of long-term cost effectiveness of projects than can be obtained with only first costs decisions. Keywords: life cycle cost, net present value, lowest long term cost of ownership, economics

 pdf fileEngineering Technology Overview Career
Engineering technologists use the principles and theories of science, engineering, and mathematics to solve technical problems in research and development, manufacturing, sales, construction, inspection, and maintenance. Their work is more limited in scope and more practically oriented than that of scientists and engineers. Many engineering technologists assist engineers and scientists, especially in research and development. Others work in quality control -- inspecting products and processes, conducting tests, or collecting data. In manufacturing, they may assist in product design, development, or production. Although many workers who repair or maintain various types of electrical, electronic, or mechanical equipment are called technologists, these workers are covered in the Handbook section on installation, maintenance, and repair occupations.

 pdf filePower Technologies Energy Data Book
1.1 - Introduction About the Power Technologies Energy Data Book (PTEDB), Fourth Edition. In 2002, the EnergyAnalysis Office of the National Renewable EnergyLaboratory(NREL) developed the first version of the Power Technologies Energy Data Book for the Office of Power Technologies of the U.S. Department of Energy (DOE). The main purpose of the data book is to compile, in one central document, a comprehensive set of data about power technologies from diverse sources. The need for policy makers and analysts to be well-informed about power technologies suggests the need for a publication that includes a diverse, yet focused, set of data about power technologies.

 pdf fileRCM GUIDE RELIABILITY-CENTERED MAINTENANCE GUIDE
Reliability-Centered Maintenance (RCM) and variations thereof are employed by thousands of public and private organizations world-wide to address a host of reliability issues in order to improve Overall Equipment Effectiveness (OEE) while controlling the Life-Cycle Cost (LCC) inherent with Asset Management and Facility Stewardship.

 pdf fileTHE COMPLIMENTARY ROLES OF RELIABILITY-CENTERED MAINTENANCE AND CONDITION MONITORING
Condition Monitoring (CM) technologies, such as vibration analysis, infra-red thermal imaging, and ultra-sonic flaw detection along with many others have been widely used for detecting eminent equipment failures in various industries. Some applications have been more successful than others. While CM technologies are founded in sound scientific practice and usually display proven track records, their application must be administered through best business practice and value added efforts. The Reliability Centered Maintenance (RCM) methodology lends itself fully to the application of the correct maintenance procedure being conducted at the correct time and by the correct person(s). The reader will discover how the RCM analysis not only advises the administration of the correct technology, but also the acceptable interval for the inspection. Also discussed, are the economic considerations of the CM technologies as part of the RCM analysis, allowing the user to investigate the level of expertise required to produce acceptable results for a given technology.

 pdf fileFail Safe and Safe Life Designs And Factor of Safety
Fail-Safe and Safe-Life Designs Aerospace engineers, for designs involving fatigue loading, developed safe-life and failsafe philosophies. The concept of fail-safe designs is extended here to include all designs that mitigate the harm caused by failure.

 pdf fileBuilding Commissioning Guidelines
Building owners spend more on complex building systems than ever before, yet many find they are not getting the performance they expect. A 1994 study of 60 commercial buildings found that more than half suffered from control problems. In addition, 40% had problems with heating, ventilation and air-conditioning (HVAC) equipment and one-third had sensors that were not operating properly.1 An astonishing 15% of the buildings studied were actually missing specified equipment. And approximately one-quarter of them had energy management control systems, economizers, and/or variable speed drives that did not run properly. Problems also frequently occur on the envelope, structural and electrical systems of many new buildings.

 pdf fileModel Systems Engineering Documents for Adaptive Signal Control Technology ASCT Systems
The purpose of this document is to guide the user through the process of developing systems engineering documents for assessment and selection of adaptive signal control technology (ASCT) systems. This document provides a structure within which you can examine your current operation (or the operation you expect to have within the near future), assess whether or not adaptive control is likely to address your issues, and then decide what type of adaptive control will be right for you. Templates are provided for the development of the systems engineering documents that are appropriate for your situation. There are instructions on how to select appropriate answers to questions, how to select statements from the examples that are provided, and what additional information you need to gather and include in the documents. This may lead you to prepare a set of requirements and a specification against which vendors may propose a solution; or it may lead you to identify one system that is particularly suitable for your needs. It may also lead you to the realization that you are not yet prepared or capable of operating an ASCT system.
