Book Description
The ASTM E3012 Standard Guide for Characterizing Environmental Aspects of Manufacturing Processes provides guidelines for formally characterizing manufacturing processes. However, the difficulty that has arisen in the early use of the standard illustrates the need for intuitive tools for helping modeling experts to conform to the specified information model. The Unit Manufacturing Process (UMP) Builder was developed at the National Institute of Standards and Technology (NIST) to provide a visual interface for helping modeling experts to conform to the specified ASTM information model. The UMP Builder, a browser-based tool, integrates symbolic mathematical and guided textual inputs, helping to consistently record manufacturing process models for environmental sustainability into a repository. The Builder also serves as a curator by providing capabilities to explore and visualize models recorded in the Builder repository. The UMP Builder is adapted from of an open source tool called the Configurable Data Curation System (CDCS) developed at NIST. The CDCS was originally developed to capture, share, and transform materials data, allowing users to upload an XML schema and create instances of that schema. In the UMP Builder, the schema used for creating the models is frozen. The schema follows the guidelines from the ASTM E3012 standard. The Builder also provides unique features that are specific in order to facilitate the modelling of UMPs. This user s guide aims to provide guidelines to use the UMP Builder. To obtain more information (especially on the architecture), please refer to the CDCS documentation.

Book Description
Manufacturing industry drives economic activity and growth around the world, but manufacturing activities consume large amounts of material, energy, and labor resources. Therefore, the impacts of manufacturing need to be accounted for and reduced. Direct benefits of manufacturing are products and income, which, in turn, influence the lives of people in the local community and the consumers purchasing the manufactured products. The design process for products and requisite manufacturing facilities should incorporate environmental and social criteria in addition to economic criteria to more comprehensively assess sustainability performance. Sustainability assessments for manufactured products and manufacturing facilities can be carried out by assessing the incremental elements of manufacturing industry, which are unit manufacturing processes (UMPs). A challenge in the research area is that current methods for UMP assessment are ad hoc and the methods do not incorporate the system as a whole. The purpose of this research is to enable sustainable manufacturing decision making by 1) unifying an assessment methodology for UMPs, 2) developing an information modeling framework for characterizing UMPs and workpieces, and 3) demonstrating UMP composability (connectivity) modeling for use in sustainability assessments. The methodology is developed through literature review, and unifies 23 different UMP manufacturing assessment methods by analyzing each for overlapping and unique steps in the approaches. Thus, a nine-step assessment methodology emerged, which has multiple applications in industry, including process and facility assessment and improvement. A next step for MPF modeling is to link UMP models by modeling the workpiece state, but supporting tools were need to identifying how to correctly model the interactions between the UMP and the workpiece. The information modeling framework developed herein provides the theoretical background for how UMP models interact by linking the function of the UMP to the effect on the workpiece and by identifying the calculation variables necessary to assess UMPs. The information modeling framework developed for composing UMP models is demonstrated through the energy analysis of a metal component. The component is manufactured by recrystallization annealing, reducing (milling), through hardening, and recovery annealing (tempering). Models are composed (connected) by utilizing knowledge of how UMPs impart transformation to the workpiece and the information embedded in the workpiece that is transported to subsequent UMPs. Workpiece information includes the geometry and properties of the current state and future states. Previous work reported in literature has focused on geometry modeling (e.g. CAD, CAM), while this work focuses on property modeling. This research develops an overarching detailed approach to manufacturing sustainability assessments through in-depth analysis of UMPs. The result of using this UMP approach will provide guidance toward a more sustainable future.

Book Description
Manufacturing, reduced to its simplest form, involves the sequencing of product forms through a number of different processes. Each individual step, known as an unit manufacturing process, can be viewed as the fundamental building block of a nation's manufacturing capability. A committee of the National Research Council has prepared a report to help define national priorities for research in unit processes. It contains an organizing framework for unit process families, criteria for determining the criticality of a process or manufacturing technology, examples of research opportunities, and a prioritized list of enabling technologies that can lead to the manufacture of products of superior quality at competitive costs. The study was performed under the sponsorship of the National Science Foundation and the Defense Department's Manufacturing Technology Program.

Book Description
This book elevates alarm management from a fragmented collection of procedures, metrics, experiences, and trial-and-error, to the level of a technology discipline. It provides a complete treatment of best practices in alarm management. The technology and approaches found here provide the opportunity to completely understand the what, the why, and the how of successful alarm systems. No modern industrial enterprise, particularly in such areas as chemical processing, can operate without a secure and reliable infrastructure of alarms and controls-they are an integral part of all production management and control systems. Improving alarm management is an effective way to provide operators with high-value support and guidance to successfully manage industrial plant operations. Readers will find: Recommendations and guidelines are developed from fundamental concepts to provide powerful technical tools and workable approaches; Alarms are treated as indicators of abnormal situations, not simply sensor readings that might be out of position; Alarm improvement is intimately linked to infrastructure management, including the vital role of plant maintenance to alarm management, the need to manage operators' charter to continue to operate during abnormal situations vs. cease operation, and the importance of situation awareness without undue reliance upon alarms. The ability to appreciate technical issues is important, but this book requires no previous specific technical, educational, or experiential background. The style and content are very accessible to a broad industrial audience from board operator to plant manager. All critical tasks are explained with workflow processes, examples, and insight into what it all means. Alternatives are offered everywhere to enable users to tailor-make solutions to their particular sites.
