SUBJECT: M.S. Thesis Presentation BY: Rakesh S. Kulkarni TIME: Tuesday, March 29, 2005, 8:00am LOCATION: MaRC Building, Room 201 TITLE: Infusion of Robustness into the Product Platform Constructal Theory Method COMMITTEE: Dr. Farrokh Mistree, Chair (ME) Dr. David Rosen, (ME) Dr. Janet Allen, (ME) SUMMARY Mass customization has emerged as a manufacturing paradigm for a number of enterprises to efficiently and effectively satisfy customers’ requirements for product variety. The competitive nature of today’s market makes it necessary for designers to have a methodology for designing customized products in such a dynamic environment. The Product Platform Constructal Theory Method (PPCTM), developed by Dr. Gabriel Hernandez, provides designers a methodical approach for synthesizing multiple modes of managing variety in the development of product platforms for customized products. Based on both hierarchical systems theory and constructal theory, the design of platforms for customizable products is represented as a problem of access in a geometric space. The use of the PPCTM results in a hierarchical organization of the modes of managing customization, as well as the specification of their range of application across the product platform. The focus in this thesis is to augment the PPCTM in order to develop an effective product platform design method that alleviates three of its major limitations: inability to deal with uncertain distributions of demand, changing design parameters and changing extents of marketplaces. The infusion of concepts of robustness helps to address the first two limitations making the product platforms unaffected by large variations in demand and design parameters. The compromise Decision Support Problem is proposed to address the third limitation of changing extents of marketplaces by strategically designing product platforms that give expected favorable results even after market expansions. The result of this work is an augmented PPCTM that facilitates the synthesis of multiple modes for managing product variety in the presence of a dynamic environment. The augmented method is used to design a line of customizable pressure vessels and hand exercisers.

TITLE: MANAGING UNCERTAINTY IN ENGINEERING DESIGN USING IMPRECISE PROBABILITIES AND PRINCIPLES OF INFORMATION ECONOMICS. SUMMARY: The engineering design community recognizes that an essential part of the design process is decision-making. Each decision consists of two main phases—problem formulation and problem solution. Existing literature focuses on problem solution using precisely known probabilities. Problem formulation has received considerably less attention. The objective of this thesis is to investigate methods for managing uncertainty during the formulation phase of engineering design decisions, focusing on situations in which probabilities are not precisely known. The existence of such situations has been recognized in the decision theory community but has not been addressed substantially in engineering design problems. The thesis seeks to identify the fundamental characteristics of uncertainty in the context of engineering design, and hypothesizes that subjective, imprecise probabilities are more general and appropriate than currently used representations. Many methods of uncertainty representation are rigorous and internally consistent, but the applicability of the starting axioms must be evaluated. Further, the thesis will develop a method for comparing the practical value of alternative problem formulations and uncertainty representations, taking into account not only the mathematical expressiveness of the formalism, but also the cost of the computations. This is an information management problem to which principles of information economics will be applied for determining an appropriate cost-benefit tradeoff. Finally, the thesis will evaluate decision policies for problems with imprecisely known probabilities.

Jason Aughenbaugh's Ph.D. Defense: Managing Uncertainty in Engineering Design using Imprecise Probabilities and Principles of Information Economics   MaRC 201, 2006-05-16 10:00:00 - 2006-05-16 11:00:00

The engineering design community recognizes decision making as an essential part of the design process. Because decisions are generally made under uncertainty, engineers need appropriate methods for modeling and managing uncertainty. Two important characteristics of uncertainty in the context of engineering design are imprecision and irreducible uncertainty. In order to model both of these characteristics, it is valuable to use probabilities that are most generally imprecise and subjective. These imprecise probabilities generalize traditional, precise probabilities; when the available information is extensive, imprecise probabilities reduce to precise probabilities. An approach for comparing the practical value of different uncertainty models is developed. The approach examines the value of a model using the principles of information economics: value equals benefits minus costs. The benefits of a model are measured in terms of the quality of the product that results from the design process. Costs are measured not only in terms of direct design costs, but also the costs of creating and using the model. Using this approach, the practical value of using an uncertainty model that explicitly recognizes both imprecision and irreducible uncertainty is demonstrated in the context of a high-risk engineering design example in which the decision-maker has few statistical samples to support the decision. It is also shown that a particular imprecise probability model called probability bounds analysis generalizes sensitivity analysis, a process of identifying whether a particular decision is robust given the decision maker’s lack of complete information. An approach for bounding the value of future statistical data samples while collecting information to support design decisions is developed, and specific policies for making decisions in the presence of imprecise information are examined in the context of engineering.

Michael Muir's M.S. Thesis Presentation: Life Cycle Assessment for Strategic Product Design and Management   MRDC 4211, 2006-08-17 10:00:00 - 2006-08-17 11:00:00

With the advent of digital imaging technology, the options available in consumer imaging have increased tremendously. Though many options have emerged, their relative environmental impacts are not clear cut. Simplistically, one might think the use of a digital camera has lesser environmental burden than a film camera because the image produced with the digital camera avoids chemicals in film developing. However, digital cameras require electronics and computers that need electricity, whose production is a contributor to greenhouse gasses like CO2. Assessment of the environmental impacts of the options can provide feedback to decision makers and insights that may reduce environmental impact through product system design. One tool that has been used to relate environmental impacts to products or services is Life Cycle Assessment (LCA). LCA, which has been standardized by the International Standards Organization in ISO14000, is used here to evaluate both film and digital imaging systems. Product and service business models are explored with ten different imaging scenarios. Four impact categories (energy use, greenhouse emission, water use and waste generation) across four life cycle phases (upstream, distribution, use, and end of life) are explored. LCA is also evaluated as a tool to facilitate strategic environmental performance issues with new and established business activities. Sensitivity analysis is performed to evaluate the impact of assumptions made in the assessment. Results indicate that the lowest impact scenarios are Digital Capture to LCD Display for Greenhouse Emissions and Energy Use and Film Capture to Wholesale Print for Water Use and Waste Generation. Highest impacts were seen for Greenhouse Emissions in the Film Capture to Retail Print scenario. In the Energy Use and Water Use category, the Digital Capture to CRT Computer Display was the highest scenario. For Waste Generation, the Digital Capture to Inkjet Print was the highest scenario.

Propagation of Imprecise Probabilities through Black Box Models   Love 210, 2006-03-30 09:00:00 - 2006-03-30 10:00:00

From the decision-based design perspective, decision making is the critical element of the design process. All practical decision making occurs under some degree of uncertainty. Subjective expected utility theory is a well-established method for decision making under uncertainty; however, it assumes that the DM can express his or her beliefs as precise probability distributions. For many reasons, both practical and theoretical, it can be beneficial to relax this assumption of precision. One possible means for avoiding this assumption is the use of imprecise probabilities. Imprecise probabilities are more expressive of uncertainty than precise probabilities, but they are also more computationally cumbersome. Probability Bounds Analysis (PBA) is a compromise between the expressivity of imprecise probabilities and the computational ease of modeling beliefs with precise probabilities. In order for PBA to be implemented in engineering design, it is necessary to develop appropriate computational methods for propagating probability boxes (p-boxes) through black box engineering models. This thesis examines the range of applicability of current methods for p-box propagation and proposes three alternative methods. These methods are applied towards the solution of three successively complex numerical examples.
