Morse ______________________________ Dr. Robert G. Wilhelm ______________________________ Dr. Jimmie A Miller ______________________________ Dr. M. Taghi Mostafavi ______________________________ Dr. Jing Xiao ii ©2017 Saeed Heysiattalab ALL RIGHTS RESERVED iii ABSTRACT SAEED HEYSIATTALAB. Data models to support metrology (Under the supervision of Dr. EDWARD P. MORSE) The Quality Information Framework (QIF) is a project initiated in 2010 by the Dimensional Metrology Standards Consortium (DMSC is an American Standards Developing Organization) to address metrology interoperability. Specifically, the QIF supports the exchange of metrology-relevant information throughout the product lifecycle from the design stage through manufacturing, inspection, maintenance, and recycling / end-of-life processing. The QIF standard is implemented through a set of XML schemas called "Application Schemas" along with common core "XML schema libraries". Of these schemas, QIF Measurement Resources and QIF Rules are the two application schemas on which this research is focused. QIF Measurement Resources is an application schema developed to provide standard representations of physical measuring tools and components, and can be used to support measurement planning, statistical studies, traceability, etc. The Resources schema was supported by the creation of a new hierarchy of metrology resources in support of the product lifecycle. The QIF Rules schema is under development to provide the language with which manufacturers can define how dimensional measurement equipment is selected for various tasks, and how this equipment is used during the measurement task.

ABSTRACT In the present climate of global competition, manufacturing organisations consider and seek strategies, means and tools to assist them to stay competitive. Computer Integrated Manufacturing (CIM) offers a number of potential opportunities for improving manufacturing systems. However, a number of researchers have reported the difficulties which arise during the analysis, design and implementation of CIM due to a lack of effective modelling methodologies and techniques and the complexity of the systems. The work reported in this thesis is related to the development of an integrated modelling method to support the analysis and design of advanced manufacturing systems. A survey of various modelling methods and techniques is carried out. The methods SSADM, IDEFO, IDEF1X, IDEF3, IDEF4, OOM, SADT, GRAI, PN, 10A MERISE, GIM and SIMULATION are reviewed.

  • The IDEF Family of Languages
    CHAPTER 10 The IDEF Family of Languages Christopher Menzel, Richard J. Mayer The purpose of this contribution is to serve as a clear introduction to the modeling languages of the three most widely used IDEF methods: IDEFO, IDEFIX, and IDEF3. Each language is presented in turn, beginning with a discussion of the underlying "ontology" the language purports to describe, followed by presentations of the syntax of the language - particularly the notion of a model for the language - and the semantical rules that determine how models are to be interpreted. The level of detail should be sufficient to enable the reader both to understand the intended areas of application of the languages and to read and construct simple models of each of the three types. 1 Introduction A modeling method comprises a specialized modeling language for represent­ ing a certain class of information, and a modeling methodology for collecting, maintaining, and using the information so represented. The focus of this paper will be on the languages of the three most widely used IDEF methods: The IDEFO business function modeling method, the IDEFIX data modeling method, and the IDEF3 process modeling method. Any usable modeling language has both a syntax and a semantics: a set of rules (often implicit) that determines the legitimate syntactic constructs of the language, and a set of rules (often implicit) the determines the meanings of those constructs. It is not the purpose of this paper is to serve as an exhaus­ tive reference manual for the three IDEF languages at issue. Nor will it dis­ cuss the methodologies that underlie the applications of the languages.

As part of thls endeavor. UHCL proposed a partnership with JSC to Jointly define and manage an integrated program of research in advanced data processing technology needed for JSC's main missions, including administrative, engineering and science responsi- bilities. JSC agreed and entered into a continuing cooperative agreement with UHCL beginning in May 1986, to Jointly plan and execute such research through RICIS. Additionally, under Cooperative Agreement NCC 9-16, computing and educaUonal facilities are shared by the two instituUons to conduct the research. The UHCL/RICIS mission is to conduct, coordinate, and disseminate research and professional level edueaUon in computing and information systems to serve the needs of the government, industry, community and academia. RICIS combines resources ofUHCLand Itsgateway affiliatestoresearch and develop materials, prototypes and publications on topics of mutual interest to its sponsors and researchers.

The language, named UEML, for Unified Enterprise Modelling Language, is not intended to replace existing languages but is intended to provide a uniform interface to enterprise modelling tools and a neutral format for exchange of enterprise models. It therefore builds on previous languages and provides constructs to cover function, information, resource and organization aspects of business entities. It is also aligned with results of CEN TC 310, ISO TC 184 and IFAC-IFIP GERAM efforts in the area of enterprise modelling and engineering. KEY-WORDS : Enterprise Modelling, Modelling languages, UEML 1. INTRODUCTION analysis. Models produced were mainly static. In the 80’s, specific methods have been proposed to model In today’s highly competitive global economy, many large manufacturing systems to support their design, business companies need to better understand and possibly with a link to simulation (e.g. IDEF suite of harness the way they operate. They must also frequently methods, GRAI method).

    EBEEC 2019 Economies of the Balkan and Eastern European Countries Volume 2019 Conference Paper Tools Used in Modeling of the Economic Processes Marian Pompiliu Cristescu Abstract The paper aims at identifying the economic process modeling languages, starting from the premise that the main beneficiaries of the resulting models are economists or decision-makers, respectively economic researchers. There are a large number of languages that have been developed with different objectives, but they have all been used to describe business processes. Languages have studied different aspects of business processes (dynamic, functional, organizational, informational) and may be more or less formal, depending on the intended use and audience. There is no easy way to classify these languages along a single dimension. However, the languages fall into four groups, clearly defined scientifically or professionally: traditional process modeling languages, object-oriented languages, dynamic process modeling Corresponding Author: languages, and the integration of languages. Economic processes are generally very Marian Pompiliu Cristescu complex and, therefore, different points can be formulated about their modeling.

The modeler is one of the primary influences in the development of the scope of the model. Together, the modeler and the project manager unfold the plan for reaching the objectives of Phase Zero. These objectives include: 1. Project definition – a general statement of “what” has to be done, “why” and “how” it will get done. 2. Source material – a plan for the physical compilation of source material, including the indexing and filing of it. 3. Author conventions – a fundamental declaration of the conventions (optional methods) by which the author chooses to make and manage the model. The products of these objectives, coupled with other descriptive and explanatory documents and information, become the products of the Phase Zero effort–the Phase Zero Kits. The purpose of these kits will be described more fully later in this section. 6.2 Project Definition 6.2.1 The Strategic Objective The first activity in the modeling project is to establish where the project is going, how, and, to some extent, why. In this process, the project manager will establish his authority and mandate for the project. Some rough guidelines establishing the scope of the project in terms of money, time, and breadth of effort will have been laid down, usually in a project manager’s authorizing documents.
