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

Componentization in the Systems Modeling Language

November 20, 2013
Author(s)
Conrad E. Bock
This paper describes new capabilities in the Systems Modeling Language that reduce the complexity of specifying systems through componentization, and increase the range of systems that can be specified. Modelers can identify portions of components

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

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
