Knowledge Intensive Collaborative Decision Support for Design Process

September 1, 2003
Author(s)
XuanFang Zha, Ram D. Sriram, W F. Lu
Engineering design is essentially a collaborative decision making process that requires rigorous evaluation, comparison and selection of design alternatives and optimization from a global perspective on the basis of different classes of design criteria

Process Specification Language for Project Information Exchange

August 1, 2003
Author(s)
Michael Gruninger, Ram D. Sriram, J. Cheng, K Law
There are many project scheduling and management programs employed in the construction industry. Standards-based translation is one way to achieve interoperability. This study discusses the applicability of the Process Specification Language (PSL) for

A Product Information Modeling Framework For Product Lifecycle Management

June 1, 2003
Author(s)
Steven J. Fenves, Ram D. Sriram, Sudarsan Rachuri, Fujun Wang
We describe a framework for representing products based on the NIST Core Product Model (CPM) and its extensions, the Open Assembly Model (OAM), the Design-Analysis Integration model (DAIM), and the Product Family Evolution Model (PFEM). These are abstract

Functional Tolerancing of a Gearbox

June 1, 2003
Author(s)
H Wang, Utpal Roy, Sudarsan Rachuri, Ram D. Sriram, Kevin W. Lyons
This paper proposes a scheme for the tolerance specification that uses the features? function information and mating condition attributes in the assembly to derive an appropriate tolerance specification as per the design intents. The proposed mirror method

Tolerance Synthesis Scheme

June 1, 2003
Author(s)
Utpal Roy, N Pramanik, Sudarsan Rachuri, Ram D. Sriram, Kevin W. Lyons
The objective of this report is to identify representations and issues for the generic assembly information model and its use in a proactive tolerance synthesis scheme. It is proposed to use the small displacement torsors (the screw parameters) as a

Towards Modeling the Evolution of Product Families

June 1, 2003
Author(s)
Fujun Wang, Steven J. Fenves, Sudarsan Rachuri, Ram D. Sriram
A strategy successfully used by manufacturing companies is to develop product families so as to offer a variety of products with reduced development costs. This paper introduces our initial research on the representation of the evolution of product

A Decomposition-Based Approach to Layered Manufacturing

June 1, 2002
Author(s)
I Llinkin, R Janardan, J J. Majhi, J Schwerdt, Miles E. Smid, Ram D. Sriram
This paper introduces a new approach for improving the performance and versatility of Layered Manufacturing (LM), which is an emerging technology that makes it possible to build physical prototypes of 3D parts directly from their computer models using a
