This paper is a review of research in product development, which we define as the transformation of a market opportunity into a product available for sale. Our review is broad, encompassing work in the academic fields of marketing, operations management, and engineering design. The value of this breadth is in conveying the shape of the entire research landscape. We focus on product development projects within a single firm. We also devote our attention to the development of physical goods, although much of the work we describe applies to products of all kinds. We look inside the "black box" of product development at the fundamentaldecisions that are made by intention or default. In doing so, we adopt the perspective of product development as a deliberate business process involving hundreds of decisions, many of which can be usefully supported by knowledge and tools. We contrast this approach to prior reviews of the literature, which tend to examine the importance of environmental and contextual variables, such as market growth rate, the competitive environment, or the level of top-management support.

Product Development Decisions: A Review of the Literature

A prevalent and pervasive view of designing is that it can be modeled using variables and decisions made about what values should be taken by these variables. The activity of designing is carried out with the expectation that the designed artifact will operate in the natural world and the social world. These worlds impose constraints on the variables and their values; so, design could be described as a goal-oriented, constrained, decision- making activity. However, design distinguish- es itself from other similarly described activities not only by its domain but also by additional necessary features. Designing involves exploration, exploring what variables might be appropriate. The process of explo- ration involves both goal variables and deci- sion variables. In addition, designing involves learning: Part of the exploration activity is learning about emerging features as a design proceeds. Finally, design activity occurs within two contexts: the context within which the designer operates and the context produced by the developing design itself. The designer’s perception of what the context is affects the implication of the context on the design. The context shifts as the designer’s perceptions change. Design activity can be now characterized as a goal-oriented, con- strained, decision-making, exploration, and learning activity that operates within a con- text that depends on the designer’s percep- tion of the context.

Robust Optimization - A Comprehensive Survey

The increasing complexity of engineering systems has sparked increasing interest in multidisciplinary optimization (MDO). This paper presents a survey of recent publications in the field of aerospace where interest in MDO has been particularly intense. The two main challenges of MDO are computational expense and organizational complexity. Accordingly the survey is focused on various ways different researchers use to deal with these challenges. The survey is organized by a breakdown of MDO into its conceptual components. Accordingly, the survey includes sections on Mathematical Modeling, Design- oriented Analysis, Approximation Concepts, Optimization Procedures, System Sensitivity, and Human Interface. With the authors'' main expertise being in the structures area, the bulk of the references focus on the interaction of the structures discipline with other disciplines. In particular, two sections at the end focus on two such interactions that have recently been pursued with a particular vigor: Simultaneous Optimization of Structures and Aerodynamics, and Simultaneous Optimization of Structures Combined With Active Control.

Multidisciplinary Aerospace Design Optimization: Survey of Recent Developments

세계화가 과연 하나의 독립변수로 사용하기에 충분할 정도로 그 의미가 명확하게 규명된 과학적 개념인가의 여부는 학계의 지속적인 의문으로 남아 있다. 특히 최근에는 현저하게 드러나고 있는 각종 반세계화 현상을 바탕으로 세계화에 대한 반론이 거세지고 있으며 일부 세계화론 주창자들조차 ‘현실’로서 세계화 현상에 대한 회의적 시각을 표출하고 있어 그 의문은 더욱 커지고 있다. 이에 따라 세계화를 설명 변수로 삼는 모든 연구 영역에서 세계화의 의미와 세계화와 관련된 연구 성과를 반추해 볼 필요성도 커지고 있다. 본 연구의 목적은 세계화의 의미 분석을 바탕으로 세계화를 안보환경 변화의 독립변수로 삼는 연구의 동향을 분석하고 연구의 방향을 제시하는데 있다. 세계화는 그 설명적 가치와 규범적 판단을 둘러싸고 논란이 계속되고 있는 개념이다. 세계화는 세계화론자를 중심으로 발전되어 온 개념이지만 이들 사이에서도 개념에 대한 합의는 존재하지 않는다. 세계화는 가장 단순하게는 하나의 현상 혹은 사건으로 간주되기도 하지만, 세계화의 본질을 규명하려는 입장에서는 세계화의 원인과 영향에 대한 인과관계는 물론 사회관계 본질이나 권력관계 변화를 적시하는 개념으로 취급하여 왔다. 그러나 세계화를 개념화하려는 노력은 수많은 하부 현상을 단일 요소로 설명해야 하며, 역으로 개념 속에 혼재되어 있는 세계화의 원인, 결과, 설명 및 규범적 판단 요소를 단순화해야 한다는 과제를 안고 있다. 특히 원인과 결과가 혼재되어 있는 세계화 개념은 현상 분석을 위한 설명체제 구성에 가장 큰 장애요인이 되고 있다. 세계화와 안보와의 관계를 다루는 연구는 대체로 세계화에 관한 중도론적 입장에서 안보에 관한 낙관론을 피하고 새로운 위협을 제시하는데 초점을 맞추는데, 이러한 경향은 안보연구에서 세계화를 가장 단순한 수준에서 정의하는 데에서 비롯된다. 그러나 지나치게 단순한 세계화 개념을 적용하는 안보연구는 질적으로 새로운 현상인 세계화를 여전히 국가중심적 시각에서 다루고 모든 안보위협을 테러리즘의 문제로 축소하려는 환원주의의 문제를 야기한다. 이러한 문제를 극복하기 위해서는 세계화 개념의 불완전성을 염두에 둔 세계화 개념에 대한 접근과 일관된 세계화 개념 적용이 요구된다. 또한 세계화 현상으로부터 직접적인 안보 사안을 도출하는 노력에서 한 차원 더 나아가 안보연구의 새로운 방향을 제시해 줄 수 있는 안보환경 변화의 전체적 특성을 분석하는 포괄적 연구가 요구된다.

A general approach for robust optimal design

Tolerance analysis is receiving renewed emphasis as industry recognizes that tolerance management is a key element in their programs for improving quality, reducing overall costs, and retaining market share. The specification of tolerances is being elevated from a menial task to a legitimate engineering design function. New engineering models and sophisticated analysis tools are being developed to assist design engineers in specifying tolerances on the basis of performance requirements and manufacturing considerations. This paper presents an overview of tolerance analysis applications to design with emphasis on recent research that is advancing the state of the art. Major topics covered are (1) new models for tolerance accumulation in mechanical assemblies, including the Motorola Six Sigma model; (2) algorithms for allocating the specified assembly tolerance among the components of an assembly; (3) the development of 2-D and 3-D tolerance analysis models; (4) methods which account for non-normal statistical distributions and nonlinear effects; and (5) several strategies for improving designs through the application of modern analytical tools.

This paper describes the development of an automatic, two-dimensional, quadrilateral element mesh generator. The methodology is based on the looping algorithm developed in part by Dr M. L. C. Sluiter. Bezier curves are used to define the boundaries of the parts to be meshed. The required interaction by the user is reduced to specifying the boundary geometry, the preferred element size and the refinement coefficient. Transition elements are automatically generated between regions of varying element sizes. The ability to offset specified boundary curves insures well-conditioned elements along the boundary. Meshes for several sample geometries are presented to illustrate the versatility of the mesh generator.

This paper addresses three questions related to the rationale for global engineering education. These questions are, Why do engineering students need to have a new set of skills, which we will collectively refer to as “global competence?” What does it mean for students to have global competence? and, What are the most important attributes of global competence? In answer to the first question, we discuss the forces and events of the past 20 years which have driven the globalization of engineering. In answer to the second question, we present 13 dimensions of global competence. To answer the third question, we present survey results from engineering educators and leaders in industry regarding the relative importance of these dimensions. We then discuss some implications of the answers to these questions.
