RISExploring the Effectiveness of Using Graveyard Data When Generating Design Alternatives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this paper is to demonstrate that unique alternative designs can be efficiently found by searching the discarded data (or graveyard) from a multiobjective genetic algorithm (MOGA). Motivation for using ...
Exploring Product Solution Differences Due to Choice Model Selection in the Presence of Noncompensatory Decisions With Conjunctive Screening Rules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research in market-based product design has often used compensatory preference models that assume an additive part-worth rule. These additive models have a simple, usable form and their parameters can be estimated using ...
Studying Dynamic Change Probabilities and Their Role in Change Propagation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Long-lived systems are likely to experience many independent modifications during their lifecycles. Prior literature provides tools for predicting how a change in a fixed system is likely to propagate, but these tools do ...
Design for the Marketing Mix: The Past, Present, and Future of Market-Driven Engineering Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The four Ps of the marketing mix (Product, Price, Place, and Promotion) serve as a framework for characterizing the marketing decisions made during the product development process. In this paper, we describe how the last ...
Assessing Lifecycle Value Using Object-Based Modeling by Incorporating Excess and Changeability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prior research suggests that excess (purposeful inclusion of margin beyond what is required for known system uncertainties) can limit change propagation and reduce system modifications. Reducing change costs increases ...
Toward Quantifiable Evidence of Excess’ Value Using Personal Gaming Desktops
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex systems may operate in scenarios where the current requirements were “unknown” at the time of their original design. Such “unknown” requirements might be outside the probability distribution expected during the ...
Performance and Design Comparison of a Bulk Thermoelectric Cooler With a Hybrid Architecture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper compares the economic viability and performance outcomes of two different thermoelectric device architectures to determine the advantages and appropriate use of each configuration. Hybrid thermoelectric coolers ...
Multi Objective Design Optimization of a Variable Geometry Spray Fuel Injector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper explores the simulationbased design optimization of a variable geometry spray (VGS) fuel injector. A multiobjective genetic algorithm (MOGA) is interfaced with commercial computational fluid dynamics (CFD) ...
A Model for Quantifying System Evolvability Based on Excess and Capacity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important factor in system longevity is servicephase evolvability, which is defined as the ability of a system to physically transform from one configuration to a more desirable configuration while in service. These ...
Evaluation of System Evolvability Based on Usable Excess
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex, largescale engineered systems are an integral part of modern society. The cost of these systems is often high, while their ability to react to emergent requirements can be low. This paper proposes evolvability, ...
