indicator Design for passenger car using fuzzy Axiomatic Design principles
Expert Systems With Applications, 2010Co-Authors: Selcuk Cebi, Cengiz KahramanAbstract:The performance of a human-machine system is related to interaction between human and machine. The main aim of the indicators used in a human machine system is to satisfy the interaction. This paper focuses on the Design of indicator panel for passenger cars based on the Axiomatic Design principles. In this study, Axiomatic Design principles proposed by Suh are used under fuzzy environment. Both independence axiom and information axiom are utilized. The independence axiom is used for the following goals; (1) obtaining a Design map, (2) determining Design parameters and their importance, and (3) calculating the functional independency of the proposed Design. In the scope of this paper, to calculate the functional independence, new formulas are presented under fuzzy environment differing from classical Axiomatic Design principles. Then, information axiom is used to determine the best Design among the Designs that satisfy independence axiom and put forward to suitable Design characteristics. Furthermore the importances of functional requirements for the indicator panel Design are determined by using fuzzy analytic hierarchy process in the presented study.

Determining Design Characteristics of Automobile Seats Based On Fuzzy Axiomatic Design Principles
International Journal of Computational Intelligence Systems, 2010Co-Authors: Selcuk Cebi, Cengiz KahramanAbstract:The performance of a product depends on if it is created in terms of expected functional requirements. A product is Designed to satisfy some certain tasks. In this study, the Design of an automobile seat is handled. Automobile seat Design procedure is based on experience and trial-and-error method, rather than structured and scientific methods. Axiomatic Design is a Design theory providing a systematic approach to engineering Design. We propose a new product development algorithm based on Axiomatic Design principles. The independence axiom of Axiomatic Design is extended to fuzzy environment. Then, an automobile seat Design process is taken into consideration by the proposed algorithm. The Design characteristics of an automobile seat and their priorities are determined. Moreover, the Design dimensions of an automobile seat are defined for Turkish drivers.

extension of Axiomatic Design principles under fuzzy environment
Expert Systems With Applications, 2010Co-Authors: Selcuk Cebi, Cengiz KahramanAbstract:Axiomatic Design gives a Design map to Designers in order to establish a scientific basis, which improves Design activities. In the classical Axiomatic Design (AD) approach, the relationships between functional requirements (FRs) and Design parameters (DPs) are defined in crisp numbers notably ''0'' or ''1''. This definition restricts relevant Designers due to the incomplete information or uncertainty in various circumstances. This study debates the adaptation of the current AD principles into fuzzy sets theory. Those transformations are expressed by the developed formulas to prove the independence degree of the Design in quantitative manner. A numerical study illustrates the logic of the proposed ideas clearly. Consequently, the proposed methodology provides a genuine link to explain the correspondences among FRs and DPs in linguistic form.

Axiomatic Design principles under fuzzy environment
2008 3rd International Conference on Intelligent System and Knowledge Engineering, 2008Co-Authors: Selcuk Cebi, C. KahrmanAbstract:Axiomatic Design gives a Design map to Designers in order to establish a scientific basic for Design and to improve Design activities. In the Axiomatic Approach, the relationship between functional requirements and Design parameters has been defined by 0 or 1. This definition, sometimes, restrict Designers under the situation that there are incomplete information or uncertainty. In this study, the use of the Axiomatic Design principles is discussed under fuzzy environment. New formulas are presented to calculate independence of the Design. Moreover, the usability of the methodology is given by a numerical example in this study. Proposed methodology provides the Designers to explain the relationship between FRs and DPs in linguistic form.

improving the requirements process in Axiomatic Design theory
Cirp Annals-manufacturing Technology, 2013Co-Authors: Mary Kathryn ThompsonAbstract:Abstract This paper introduces a model to integrate the traditional requirements process into Axiomatic Design Theory and proposes a method to structure the requirements process. The method includes a requirements classification system to ensure that all requirements information can be included in the Axiomatic Design process, a stakeholder classification system to reduce the chances of excluding one or more key stakeholders, and a table to visualize the mapping between the stakeholders and their requirements.

a classification of procedural errors in the definition of functional requirements in Axiomatic Design theory
7th International Conference on Axiomatic Design (ICAD 2013), 2013Co-Authors: Mary Kathryn ThompsonAbstract:The definition of functional requirements is one of the most critical and difficult steps in the Axiomatic Design process. This paper presents five classes of procedural errors made by both novice and expert Designers during the definition of functional requirements in Axiomatic Design Theory. Each category is described in detail, the linguistic markers for the errors are identified, examples from the literature are provided, and strategies for avoiding these errors are suggested. The implications of these errors for Design practitioners, educators, and researchers are considered. The paper ends with a discussion about the nature of requirements and future requirements research topics in Axiomatic Design Theory.

The Application of Axiomatic Design Theory and Conflict Techniques for the Design of Intersections: Part 1
2009Co-Authors: Mary Kathryn Thompson, Oh Hoon Kwon, Min Ju ParkAbstract:Today the Design and analysis of traffic intersections is most commonly done using traditional traffic conflict techniques. In this paper, we compare and combine traditional traffic conflict techniques and Axiomatic Design theory. Both the conflict techniques and Axiomatic Design theory are applied to a generic 4-way intersection. Strategies to improve the intersection including separation of space and separation of time are considered. The limitations and implications of conflict techniques, Axiomatic Design theory, and the two strategies are addressed. Finally, the future implications of this work are discussed.

teaching Axiomatic Design in the freshman year a case study at kaist
International Conference on Auditory Display, 2009Co-Authors: Mary Kathryn ThompsonAbstract:Axiomatic Design theory was once considered the domain of engineering doctoral candidates and industry experts in search of an improved understanding of Design. However, an innovative freshman Design course at KAIST is using Axiomatic Design Theory, along with traditional product Design and TRIZ, to improve the students’ ability to think independently, consciously, rationally, and synthetically. This paper discusses the basic format, goals, and philosophy for ED100: Introduction to Design and Communication. Finally, the successes, challenges, and the future implications of the course are also discussed.

The Faucet Reloaded: Improving Axiomatic Design by Example
MATEC Web of Conferences, 2017Co-Authors: Joseph Timothy Foley, Erik Puik, David S. CochranAbstract:Axiomatic Design Theory and Complexity Theory have made large impacts in the research of Design methodologies, but a major obstacle to widespread use is the challenge of teaching it. A standard example used for educating students on the importance of coupling in Functional Requirements involves the difference between a two-valve and a lever-type faucet. Unfortunately, this simplistic example has its limitations in implementation due to imbalances in pressure and temperature variation. Strangely enough, these limitations turn out to be inspirations for expanding the example to make it better for teaching Axiomatic Design and Complexity Theory. In this work, we update the faucet example to map it to real-world application. Secondly, the concepts of ‘Information in Design’ and ‘Complexity in Axiomatic Design’ are explained from a perspective that increases understanding and acceptation by students and learning professionals. Lastly, we highlight other illustrative examples in manufacturing including the Manufacturing System Design Decomposition.

Using Axiomatic Design to support the development of a balanced scorecard
International Journal of Business Performance Management, 2001Co-Authors: David S. Cochran, James Duda Campinas, Carlos Eduardo D´araujo Vilaça Lobo, Paulo Corrêa LimaAbstract:This paper shows how the principles of Axiomatic Design can be used to develop a balanced scorecard. To develop a balanced scorecard, companies usually use cause-effect diagrams to link the strategic plan with the enterprise scorecard, and the performance of every worker to the enterprise's overall performance. Using Axiomatic Design to make these links and develop performance measures is proposed. A brief example is presented to show how this method avoids highly coupled Designs, provides guidance in terms of how the objectives can be achieved, and facilitates the tracking and linking of measures across various levels of the scorecard hierarchy.

reviewing triz from the perspective of Axiomatic Design
Journal of Engineering Design, 2000Co-Authors: David S. CochranAbstract:TRIZ is a Russian acronym for the Theory of Inventive Problem Solving, which is a little-known algorithmic system for solving engineering problems. It has been developed by Altshuller and colleagues for over 50 years in the former Soviet Union (he started his work on an algorithm for the solution of inventive problems in 1946). Axiomatic Design has been developed by Suh and colleagues at Massachusetts Institute of Technology in the USA for about 20 years (their first paper was published in 1978; Suh et al. (1978)). Both theories have lately gained popularity due to the need for a science-based Design methodology. Interestingly, many concepts of the two Design theories seem to be in coincidence, even though they have been developed quite independently for a long time. In this paper, several concepts of TRIZ are reviewed from the standpoint of Axiomatic Design. The concept of ideality, the concept of conflicts (or contradictions) and the Sufield model of TRIZ are studied and explained using the Axiomatic De...

Axiomatic Design of Manufacturing Systems
1996Co-Authors: David S. Cochran, Vicente A. ReynalAbstract:Abstract This paper introduces the use of Axiomatic Design in the Design of manufacturing systems. The twoprimary functional requirements of any manufacturing system are developed. These functional requirementsare used to analyze the Design of four manufacturing systems in terms of system performance. The purposeof this work is to provide a new foundation for describing, determining and rationalizing the Design of anynew manufacturing system. Introduction The motivation for the application of Axiomatic Design to describe the Design ofmanufacturing systems is threefold. The first reason is that a revolution has occurred interms of the Design and operation of manufacturing systems. This change is marked bymany of the methods spawned by the Toyota Production System and subsequently, thecharacterizations of lean and agile manufacturing. Academia and industry have notdefined the fundamental Design principles that characterize the changes that haveoccurred. Industrial and business publications have largely enumerated characteristics ofsystems. These characterizations are often portrayed by buzz or catch words. To be ableto advance manufacturing system Design and new manufacturing paradigms, the Designprinciples must be understood.The second reason is that a methodology must be used to systematically relate the desiredDesign outcomes (known as functional requirements in Axiomatic Design terminology) tothe Design principles and Design parameters that are used to achieve the desired result.Since systems embody a complex arrangement of physical elements characterized bymeasurable parameters with corresponding inputs and outputs [Black, 1990] and sincelarge systems must meet the time-variant nature of changing functional requirements, thecorresponding Design parameters of a system must be adaptable over time [Suh,1995].The message is the need to be able to systematically propagate the functionalrequirements of system to the various facets of a system’s Design. Specifically, withinmanufacturing systems we define the interactions that occur within the following facets orlevels within a system: production system level, manufacturing system, sub-system or

Independence Measure (IM) Using Independence Priority Number (IPN) in Axiomatic Design Framework
Volume 15: Advances in Multidisciplinary Engineering, 2015Co-Authors: Sung-hee DoAbstract:Axiomatic Design is becoming a preferred system Design process tool for insuring the quality and efficiency of Design processes for products and services. One aspect of Axiomatic Design is modeling and analyzing the functional independence of proposed solutions. Axiomatic Design provides for comparing and ranking solutions by three categories of functional coupling: Uncoupled, Decoupled and Coupled (1). However, given two potential solutions within the same functional coupling category, Axiomatic Design technology cannot further rank these solutions without additional information. This paper proposes that the degree of functional coupling can be assessed to provide further discrimination between solutions within the same coupling category. Using complexity concepts, this paper proposes two additional metrics, the Independence Priority Number (IPN) and the Independence Measure (IM) to further rank the potential robustness of alternative solutions using the Independence Axiom of the Axiomatic Design process. With IPN and IM metrics, Design professionals can better assess the functional robustness of their proposal at the earliest phase of Design, conceptual Design synthesis.Copyright © 2015 by ASME

Axiomatic Design approach for marine Design problems
Marine Structures, 2002Co-Authors: Young-soon Yang, Beom Seon Jang, Sung-hee Do, Yun-seog Yeun, Yu-suk SongAbstract:The Axiomatic Design approach proposed by N.P. Suh consists of the Independence Axiom and the Information Axiom. The Independence Axiom assists a Designer in generating good Design alternatives by considering the relationships between the functions and the physical product using a hierarchical mapping procedure. The Information Axiom, which is related to the probability of achieving the given functional requirements, can be used as a criterion for the selection of the best solution among the proposed alternatives in the conceptual or preliminary Design stage.\nIn the early stages of marine Design, especially ship Design, there exists a lot of uncertainty because of the size and complexity of a marine vehicle. This uncertainty often leads to a probabilistic approach rather than a deterministic approach. Ship Designs are often routine, requiring small modifications of an existing, successful Design. The availability of Axiomatic Design in this marine Design field has been investigated through four examples: a conceptual thruster Design, a foil-strut optimization problem, a main engine selection problem, and a barge Design problem. By these examples, the possibility of the application of Design Axioms in marine Design has been illustrated.

Axiomatic Design of software systems
CIRP Annals, 2000Co-Authors: Sung-hee DoAbstract:Abstract Software is playing an increasingly important role in manufacturing. Many manufacturing firms have problems with software development. Software engineering is still labor- intensive and prone to errors. Industrial firms are under pressure to shorten the lead-time required in introducing new software, increase the reliability of their software, and increase their market share. Software must be Designed correctly from the beginning to end. With this end in mind, Axiomatic Design theory has been applied to software Design. This paper presents how the combination of Axiomatic Design has been combined with the object-oriented programming method to create a large software system.
