Towards Proper-Inconsistency In Weldability Prediction Using K-Nearest Neighbor Regression And Generalized Regression Neural Network With Mean Acceptable Error, Junheung Park, Kyoung-Yun Kim, Raj Sohmshetty Jan 2014

Towards Proper-Inconsistency In Weldability Prediction Using K-Nearest Neighbor Regression And Generalized Regression Neural Network With Mean Acceptable Error, Junheung Park, Kyoung-Yun Kim, Raj Sohmshetty

Center for e-Design Proceedings

A significant inconsistency problem exists in the quality of resistance spot welding, and yet it offers various advantages in production. These inconsistent welding data can be eliminated using anomaly detection or instance selection methods. However, in the weldability prediction problem, this inconsistency we refer to as proper-inconsistency, may not be eliminated since it can be used to extract additional information. In this research, we examine the effects of this inconsistency on prediction performance using two machine learning methods, k-Nearest Neighbors (kNN) regression and Generalized Regression Neural Network, in order to identify an approach towards tackling the proper-inconsistency problem in weldability ...


Harmonized Decision Modeling Process For Smart Grid Component Allocation, Seung Yup Kim, Kyoung-Yun Kim, Evrim Dalkiran Jan 2014

Harmonized Decision Modeling Process For Smart Grid Component Allocation, Seung Yup Kim, Kyoung-Yun Kim, Evrim Dalkiran

Center for e-Design Proceedings

This article presents a harmonized decision modeling framework for smart grid component allocation. The harmonized decision modeling process is intended to realize a decision support system for the smart grid system analysis. The traditional decision modeling processes have mainly stresses the economic feasibility of smart grid systems. However, the mathematical programming-based decision models for component allocation in smart grid systems are often designed without the enough consideration on the operational circumstances of component, and it reduces the utility of the solution. Our framework considers the operational circumstances of the system and the feasibility in terms of solving process for achieving ...


Evaluation Framework For Crowdsourced Design Concept Management, Jihoon Kim, Kyoung-Yun Kim, Ohbyung Kwon Jan 2014

Evaluation Framework For Crowdsourced Design Concept Management, Jihoon Kim, Kyoung-Yun Kim, Ohbyung Kwon

Center for e-Design Proceedings

Crowdsourced design concepts are reported to be more creative than internal ideas and the cost of idea sourcing from the crowds is less expensive than from the conventional sources. However, the crowdsourced design has not been well utilized especially for complex engineering systems. One of the reasons is that the crowdsourced data, information, and knowledge are not well managed and evaluated to generate the expected quality and feasibility. The aim of this paper is to present an evaluation framework for crowdsourced design concept management and to couple ideas and solutions with the purposes or objectives of new product development, more ...


An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis Jan 2013

An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis

Center for e-Design Proceedings

The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support such a process, we propose the development of an environment where sustainability considerations are explicitly introduced early into the design process. This explicitness is provided by integrating the requirements information of sustainability standards and regulations directly into the design process. The emergence of the semantic web provides an interoperable environment in which the context and meaning of knowledge about the relationships among various domains can be ...


Support Of Product Innovation With A Modular Framework For Knowledge Management: A Case Study, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden Jan 2011

Support Of Product Innovation With A Modular Framework For Knowledge Management: A Case Study, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Proceedings

This paper presents an e-Design framework for knowledge management through its application in an engineering design case study. The e-Design framework enables the implementation of integrated design information throughout the entire design process. It facilitates the ease of sharing real time information across multiple individual designers, departments, or organizations as would be required in large scale design efforts. Similarly, it allows for the ease of use of technical tools integral to the design process that small design departments depend upon. Thus, regardless of the scale, the efficiency of engineering design can be improved with the use of the e-Design framework ...


Towards Industrial Implementation Of Emerging Semantic Technologies, Jay T. Brindel, Ian R. Grosse, Sundar Krishnamurty, John Altidor, Seth Trachtenberg, Paul Witherell Jan 2011

Towards Industrial Implementation Of Emerging Semantic Technologies, Jay T. Brindel, Ian R. Grosse, Sundar Krishnamurty, John Altidor, Seth Trachtenberg, Paul Witherell

Center for e-Design Proceedings

Every new design, project, or procedure within a company generates a considerable amount of new information and important knowledge. Furthermore, a tremendous amount of legacy knowledge already exists in companies in electronic and non-electronic formats, and techniques are needed for representing, structuring and reusing this knowledge. Many researchers have spent considerable time and effort developing semantic knowledge management systems, which in theory are presumed to address these problems. Despite significant research investments, little has been done to implement these systems within an industrial setting. In this paper we identify five main requirements to the development of an industry-ready application of ...


Semantic Relatedness Measures For Identifying Relationships In Product Development Processes, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden Aug 2009

Semantic Relatedness Measures For Identifying Relationships In Product Development Processes, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Proceedings

The Semantic Web, especially in relation to ontologies, provides a structured, formal framework for knowledge interoperability. This trait has been exploited by both the biomedical community in development of the Human Gene Ontology [1] and also by geographers in development of geospatial ontologies [2]. Using semantic relatedness techniques, researchers from both communities have been able to develop and integrate comprehensive knowledge bases. Beyond knowledge integration, semantic relatedness techniques have also been able to provide each community with a unique insight into relationships between concepts in their respective domains. In the engineering community, semantic relatedness techniques promise to provide similar insight ...


A Decision Support Ontology For Collaborative Decision Making In Engineering Design, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Jan 2009

A Decision Support Ontology For Collaborative Decision Making In Engineering Design, Justin A. Rockwell, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Proceedings

Complex products and increasing domain specialization have led to a collaborative design environment in which multiple partners are relied upon to successfully realize a product. In such an environment there is a need for computational frameworks that assist in communicating decision making knowledge. In this research a Decision Support Ontology (DSO) is developed to facilitate decision making within collaborative design. The structure of the information model developed reflects a priori knowledge of decision making and supports the communication of information independent of any specific decision method. Accordingly, the DSO includes decision-related information such as the design issue, alternatives, evaluation, criteria ...


Analyzing And Implementing A Feature Mapping Approach To Cad System Interoperability, John Altidor, Jack C. Wileden, Yiwen Yang, Leen Hanayneh, Yan Wang Jan 2009

Analyzing And Implementing A Feature Mapping Approach To Cad System Interoperability, John Altidor, Jack C. Wileden, Yiwen Yang, Leen Hanayneh, Yan Wang

Center for e-Design Proceedings

Interoperable information exchange between computer-aided design (CAD) systems is one of the major problems to enable information integration in a collaborative engineering environment. Although a significant amount of work has been done on the extension and standardization of CAD data formats as well as the cooperation of CAD systems in both academy and industry, these approaches are generally low-level and narrowly targeted. Lack of fundamental study of interoperability and generic solution to this problem is the major issue. Our intention of this research is to design a solution of CAD feature interoperability as generic as possible based on a theoretical ...


A Web-Based Environment For Documentation And Sharing Of Engineering Design Knowledge, Justin A. Rockwell, Paul Witherell, Rui Fernandes, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Jan 2008

A Web-Based Environment For Documentation And Sharing Of Engineering Design Knowledge, Justin A. Rockwell, Paul Witherell, Rui Fernandes, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Proceedings

This paper presents the foundation for a collaborative Web-based environment for improving communication by formally defining a platform for documentation and sharing of engineering design knowledge throughout the entire design process. In this work an ontological structure is utilized to concisely define a set of individual engineering concepts. This set of modular ontologies link together to create a flexible, yet consistent, product development knowledge-base. The resulting infrastructure uniquely enables the information stored within the knowledge-base to be readily inspectable and computable, thus allowing for design tools that reason on the information to assist designers and automate design processes. A case ...
