A Standards and Technology Roadmap for Scalable Distributed Manufacturing Systems

June 19, 2018
Author(s)
Thomas D. Hedberg Jr., Moneer Helu, Timothy A. Sprock
The increasing decentralization of manufacturing has contributed to the growing interest in scalable distributed manufacturing systems (DMSs). The emerging body of work from smart manufacturing, Industrie 4.0, Industrial Internet of Things (IIoT), and

Manufacturing and Contract Service Networks: Composition, Optimization and Tradeoff Analysis based on a Reusable Repository of Performance Models

January 15, 2018
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, Mohomad O. Nachawati, William Z. Bernstein, Daniel A. Menasce
In this paper we report on the development of a software framework and system for composition, optimization and trade-off analysis of manufacturing and contract service networks based on a reusable repository of performance models. Performance models

Extending and Evaluating the Model-based Product Definition

December 22, 2017
Author(s)
Nathan W. Hartman, Jesse Zahner, Thomas D. Hedberg Jr., Allison Barnard Feeney
Industrial practice is in a state of transition, away from the use of drawings towards the use of annotated 3D CAD models as a means of communication. Working as a representation of an object or a system, a model-based product definition (MBD) is used to

Business Process Context for Message Standards

September 7, 2017
Author(s)
Nenad Ivezic, Miroslav Ljubicic, Marija Jankovic, Boonserm Kulvatunyou, Scott Nieman, Garret Minakawa
Despite unrelenting increase in complexity of message standards for enterprise systems integrations, there are no effective means to address this complexity issue in practice. We describe an effort to address the issue by advancing message standards

Using DITA to Create Security Configuration Checklists

July 31, 2017
Author(s)
Joshua Lubell
Many software tools use security configuration checklists expressed in the Extensible Configuration Checklist Description Format (XCCDF) to monitor computers and other information technology products for compliance with security policies. But XCCDF syntax

A Semantic Product Modeling Framework and Its Application for Behavior Evaluation

January 9, 2012
Author(s)
Jae H. Lee, Steven J. Fenves, Conrad E. Bock, Sudarsan Rachuri, Hyo-Won Suh, Xenia Fiorentini, Ram D. Sriram
Supporting different stakeholder viewpoints across the product’s entire lifecycle requires semantic richness to represent product related information and thus enable multi-view engineering simulations. This paper proposes a multi-level product modeling

Ontological Product Modeling for Collaborative Design

July 22, 2010
Author(s)
Conrad E. Bock, XuanFang Zha, Hyo-won Suh, Jae H. Lee
This paper shows how to combine ontological and model-based techniques in languages that facilitate collaborative design exploration. The proposed approach uses ontology to capture alternative designs and incremental refinements that meet requirements and

Ontological Product Modeling for Collaborative Design

October 30, 2009
Author(s)
Conrad E. Bock, XuanFang Zha, Hyo W. Suh, Jae H. Lee
This paper presents a product modeling language for collaborative design that has the benefits of ontology and expanded capabilities in conventional product modeling. The proposed approach uses ontology to increase flexibility and accuracy in combining

SysML and UML 2 Support for Activity Modeling

June 1, 2005
Author(s)
Conrad E. Bock
This article describes activity modeling as specified by the Systems Modeling Language (SysML) and the finalization of the Unified Modeling Language version 2 (UML 2). It reviews and updates an earlier proposed alignment between Enhanced Functional Flow

PSL: A Semantic Domain for Flow Models

May 1, 2005
Author(s)
Conrad Bock, Michael Gruninger
Flow models underlie popular programming languages and many graphical behavior specification tools. However, their semantics is typically ambiguous, causing miscommunication between modelers and unexpected implementation results. This article introduces a

Systems Engineering in the Product Lifecycle

May 1, 2005
Author(s)
Conrad E. Bock
This article introduces basic elements of systems engineering that are useful in managing the product lifecycle, as expressed in an extension to the Unified Modeling Language. Models are described for product requirements in textual and computable form

UML 2 Activity and Action Models, Part 6: Structured Activities

April 1, 2005
Author(s)
Conrad E. Bock
This is the sixth in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model [1]. The first article gives an overview of activities and actions [2], while the next four cover

UML 2 Composition Model

October 1, 2004
Author(s)
Conrad E. Bock
The composition model in the Unified Modeling Language, version 2, is a major upgrade to the familiar black diamond composition of earlier versions. It supports connections between parts at the same level of decomposition, in addition to the usual part

UML 2 Activity and Action Models, Part 5: Partitions

April 1, 2004
Author(s)
Conrad E. Bock
This is the fifth in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model. The first article gives an overview of activities and actions, while the next three cover actions

UML 2 Activity and Action Models, Part 3: Control Nodes

January 1, 2004
Author(s)
Conrad E. Bock
This is the third in a series introducing the activity model in the Unified Modeling Language, version 2 (UML 2), and how it integrates with the action model. The previous article addressed the execution characteristics of actions in general, and
