- Collaborative engineering among designers with different preferences: Application of the preference set-based design to the design problem of an automotive front-side frame
Masato Inoue; Yoon-Eui Nahm; Kenji Tanaka; Haruo Ishikawa
The advancement of computer networks and information technologies has been rapidly changing the manufacturing environment of the industrial age to that of the current information era. The engineering philosophy has been shifted from concurrent engineering to collaborative engineering among the respective areas of expertise in a design space. Handling uncertainties in an initial design process is of great importance, particularly for collaborative engineering. For collaborative engineering, designers having different preferences in the different disciplines need to represent their own possible design solutions or design solution spaces, and they also need to understand the other designers' design solution spaces. We have proposed a preference set-based design method that enables a flexible and robust design under various sources of uncertainties, while capturing a designer's preference. In this study, the proposed method was applied to a real industrial multi-objective design problem (i.e. an automotive front-side frame design). This study discusses the suitability of our proposed approach for obtaining the multi-objective satisfactory solutions that reflect the different design preferences of different designers in their design solutions for collaborative engineering. © The Author(s) 2013., Dec. 2013, Concurrent Engineering Research and Applications, 21, 4, 252-267, English, 1063-293X, 84888608397 - Collaborative engineering among designers with different preferences: Application of the preference set-based design to the design problem of an automotive front-side frame

Masato Inoue; Kai Lindow; Rainer Stark; Kenji Tanaka; Yoon-Eui Nahm; Haruo Ishikawa
A satisfactory multiobjective design that incorporates physical performance as well as sustainability is necessary from a global environmental protection perspective. For obtaining sustainable lifecycles, decision making in the early phases of the design process, considering multiple sources of uncertainty, is important. Previously, we proposed a preference set-based design (PSD) by Inoue et al. (2010) [16] method, which enables a flexible and robust design under various sources of uncertainty while capturing the designer's preference based on his/her knowledge or experience. The present study focuses on a decision-making support for sustainable product creation in the early phases of the design process considering the various design uncertainties. We investigate different officially accepted sustainability indicators and identify the ones that are related to the product development process by considering the physical performance and sustainability of the products concurrently. Thereafter, the proposed method is applied to a multiobjective design problem. This paper discusses the applicability of PSD as a decision-making support method for sustainable development using the design of an alternator as an example. (C) 2012 Elsevier Ltd.

Masato Inoue; Yoon-Eui Nahm; Soshi Okawa; Haruo Ishikawa
Various computer-based simulation tools such as 3D-CAD systems and CAE are widely used to design products at the early phase of design. Designers must search the optimal solution that satisfies a number of performance requirements by repeating analysis and modification of the CAD models. They need to confirm the results of CAE analysis until they can obtain a better design solution. These works impose a heavy burden on designers and analysts. Therefore, design works can be more efficient if we can automate these iterative processes. Moreover, the early phase of design contains multiple sources of uncertainty in describing design, and nevertheless the decision-making process at this phase exerts a critical effect upon drawing a successful design. Therefore, handling the uncertainties in the early phase of design has great importance especially for concurrent engineering (CE). The previous series of our studies have proposed a preference set-based design (PSD) method that enables the flexible and robust design while incorporating designer's preference structure. In contrast to conventional optimization techniques, this method generates a ranged set of design solutions that satisfy sets of performance requirements. The combination of 3D-CAD and CAE with PSD method can be more powerful design support system. In this study, a system based on PSD method is implemented by combination of 3D-CAD and CAE, and a design example of a swing arm is demonstrated to show the effectiveness of the proposed system for obtaining the multi-objective satisfactory solutions reflecting the designers' intentions., SAGE PUBLICATIONS LTD, Mar. 2010, CONCURRENT ENGINEERING-RESEARCH AND APPLICATIONS, 18, 1, 41-53, English, 1063-293X, 1531-2003, WOS:000276165800004 - Design Support System by Combination of 3D-CAD and CAE with Preference Set-based Design Method

YE Nahm; H Ishikawa
This work is motivated from set-based concurrent engineering (SBCE) paradigm. In contrast to the traditional design practice, SBCE considers a broader range of design possibilities (i.e., design space) from the outset, explicitly communicates and reasons about sets of design alternatives, and gradually narrows the sets to eliminate inferior alternatives until a final solution remains. Thus, the key to success of SBCE is the proper implementation of the space representation method to define the possible design region, the space mapping method to obtain the performance space achievable by the initial design space, and the space narrowing method to eliminate infeasible subspaces from the initial design space. This paper proposes a novel space-based design methodology for preliminary engineering design. The main characteristic features of our approach are to incorporate the designer's preference structure with degrees of desirability in specifying both design space and performance space, and to find a ranged set of design solutions that satisfy changing sets of performance requirements through set-to-set space mapping from design space to performance space and space narrowing to eliminate infeasible design subspaces. Central to the proposed design methodology is the integration of meta-modeling techniques, modified fuzzy arithmetic, design of experiment (DoE), robust design techniques, and uncertainty analysis. A preliminary parametric design example of a vehicle side impact beam is demonstrated to show the effectiveness of the proposed methodology and its availability in the large-scale multi-objective design synthesis problem., SPRINGER LONDON LTD, May 2006, INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY, 28, 11-12, 1056-1070, English, 0268-3768, 1433-3015, WOS:000236974600002 - Novel space-based design methodology for preliminary engineering design

Q. Wang; K. Ozaki; H. Ishikawa; S. Nakano; H. Ogiso
A depth-sensing indentation system was used to measure the residual stress in a stainless steel plate implanted by Fe2+ ions with an energy of 3 MeV at a dose of 3 × 1016 cm-2. Unlike other measurement methods, such as substrate curvature and X-ray diffraction techniques, depth-sensing indentation provides an accurate measurement of local residual surface stresses in the thin ion-implanted layer. Micromechanical analysis was carried out based on the premise that elastic unloading responses during indentation are fully independent of any pre-existing residual stresses at the indented surface. The correctness of this premise was verified by FEM simulation. It is found that the surface stress is proportional to the load shift induced by the surface stress. By using the energy method, a formula was derived for determining the surface stress by depth-sensing indentation studies. The residual surface stress induced by ion implantation was evaluated by using this formula. © 2005 Elsevier B.V.

Part II: its applications to concurrent engineering design
YE Nahm; H Ishikawa
Concurrent or collaborative engineering (CE) has inspired research in the area of design decomposition, which facilitates the concurrency of product lifecycle functions from the earlier stage of the product development process and reduces the complexity of a design problem. The decomposition-based design, on the other hand, necessitates various integration efforts for recombining the decomposed design problems. This is the second of a two-part paper proposing a multi-agent system (MAS) framework for integrated product design in a computer network-oriented CE environment. Part II discusses the applications of the proposed MAS framework to concurrent engineering design. The proposed framework realises the systematic and timely design integrations between multi-functional/cross-functional team members in a dynamic design environment, by enabling model integration, solution integration and tool integration. The proposed design agents make the problem-specific engineering models or heterogeneous design tools interoperable and network-accessible, and also provide the interaction spaces for communicating, integrating or coordinating the individual design solutions. Throughout the paper, the proposed system is illustrated with a successful implementation of a continuously variable transmission (CVT) design problem over the Internet ., SPRINGER LONDON LTD, Jan. 2006, INTERNATIONAL JOURNAL OF ADVANCED MANUFACTURING TECHNOLOGY, 27, 5-6, 431-444, English, 0268-3768, WOS:000233725700002 - 初期設計段階におけるセットベース多目的設計最適化（第3報） ドア構造設計問題への適用

During the past two decades, concurrent or collaborative engineering (CE) has presented new possibilities for successful product development. In addition, the advances in computer networks and information technology have brought engineering design context into a new era. As a promising approach to accommodate the radical pace of changes in the context of engineering design, agent technologies have been attracting public attention and are being used in an increasingly wide variety of applications. However, little attention has been paid to multi-agent system (MAS) frameworks for CE environments that enable systematic and timely design integrations in both hierarchical and heterarchical design topology.

YE Nahm; H Ishikawa
The manufacturing industries are now experiencing fierce pressure of competition from every corner on this planet. In addition, the advancement in computer networks and information technologies has been gradually reshaping the manufacturing companies by shifting from the industrial age to the information era. Due to these elevated competitiveness and advanced computer technology, a number of new manufacturing and management strategies (e.g., CE or CIM) have emerged for the innovation of manufacturing enterprises. Although they have different definitions and scopes, there are several common issues: inter-enterprise functions integration; inter-enterprise resources integration; and collaboration. This paper proposes a new multi-agent system (MAS) architecture to support the inter-enterprise functions/resources integration and collaboration over the networked environment, including the hybrid agent architecture and hybrid network architecture. In contrast to the existing agent architectures, the proposed agent architecture enables agents to exhibit the hybrid (continuous and discrete) behavior and interactions. In addition, our network architecture is more suitable for building the large-scale distributed manufacturing systems that are prone to dynamic random changes of their environment. Based on the proposed MAS architecture, a collaborative product development environment is implemented as a starting point, and a multidisciplinary team-oriented design problem is illustrated to provide the vision of the proposed MAS architecture.

YE Nahm; H Ishikawa
The early phase of design intrinsically contains multiple sources of uncertainties in describing the design, and nevertheless the decision-making process at this phase exerts a critical effect upon drawing a successful design. Recently, set-based concurrent engineering (SBCE) has been attracting public attention as an emerging CE paradigm. Representing and communicating set-valued information are useful in handling engineering uncertainties and efficient for the collaboration between designers in the CE environment. Even if we can readily know that SBCE is efficient and powerful enough for large-scale design and management, the existing literature does not give the details of methods to achieve SBCE principles. We have developed a computer-based framework, called 'preference set-based design' (PSD), for implementing SBCE principles, which consists of set representation, propagation, modification, narrowing, and aggregation methods. This article focuses on the set representation and aggregation methods that play an important role in the CE environment. This article proposes new engineering quantities that can capture the designer's preference structure on both the continuous and the discrete sets. A new aggregation method is presented to aggregate the proposed engineering quantities. A comparative analysis with the existing representation and aggregation techniques is also provided., SAGE PUBLICATIONS LTD, Jun. 2005, CONCURRENT ENGINEERING-RESEARCH AND APPLICATIONS, 13, 2, 123-133, English, 1063-293X, WOS:000229154700004 - A hybrid multi-agent system architecture for enterprise integration using computer networks

This article focuses on the set representation and aggregation methods that play an important role in the CE environment. This article proposes new engineering quantities that can capture the designer's preference structure on both the continuous and the discrete sets. A new aggregation method is presented to aggregate the proposed engineering quantities. A comparative analysis with the existing representation and aggregation techniques is also provided., SAGE PUBLICATIONS LTD, Jun. 2005, CONCURRENT ENGINEERING-RESEARCH AND APPLICATIONS, 13, 2, 123-133, English, 1063-293X, WOS:000229154700004 - Set-Based Design Methodology and its Application to Design of Automobile Body

2005, International Society for Productivity Enhancement - Effects of substrate temperature during implantation on the mechanical properties of ion-implanted silicon
Q Wang; H Ishikawa; H Ogiso; S Nakano; J Akedo
Ion implantation causes changes in mechanical properties such as hardness and fracture toughness on the ion-implanted surface. The purpose of this study is to experimentally investigate the effects of substrate temperature during ion implantation on the hardness and fracture toughness of an ion-implanted silicon wafer. A silicon (10 0) wafer was implanted by 3 MeV ions of Au and Si at different substrate temperature of 100, 200 and 300 K, respectively. After ion implantation, Vickers indentation experiments were carried out on the ion-implanted surface of the silicon wafer at room temperature. The results of the Vickers indentation tests show a significant decrease of hardness and an increase of fracture toughness of the ion-implanted silicon with decreasing the substrate temperature during ion implantation. It was found that the lower the substrate temperature during implantation, the greater the effectiveness of ion implantation on the changes in mechanical properties of the ion-implanted silicon.

YE Nahm; H Ishikawa
Concurrent engineering (CE) has been widely accepted as an effective engineering practice for decreasing product development time, improving quality, decreasing manufacturing costs, and improving customer satisfaction. Since CE philosophy is intended to consider all elements of product life cycle from the outset, CE approach increases the complexity of design problem and makes it more difficult to manage. In addition, the advances in computer networks and information technology have brought engineering design into a new era. Although a considerable number of studies have been made on design decomposition (e.g., product and process (or perspective) decomposition) as a means to reduce the complexity of a large scale design problem, relatively little attention has been given to the computational framework for dynamic and systematic design integration in a computer network-oriented design environment. This paper describes an integrated product and process modeling (IPPM) framework for collaborative product design through the Internet. Here, the hierarchical and heterarchical dependencies between the decomposed smaller design problems are addressed. An agent-based approach is proposed for the computer support of hierarchical and heterarchical design topologies. In our framework, a smaller design problem is dynamically modeled in terms of interacting and pluggable design agents that represent a specific aspect of the design problem and provide the interoperability between heterogeneous design agents or software applications, and the results of these smaller problems are recursively integrated to formulate solutions to the larger problems in a systematic manner. Finally, the proposed framework forms a global design network through which a number of design possibilities are explored., SAGE PUBLICATIONS LTD, Mar. 2004, CONCURRENT ENGINEERING-RESEARCH AND APPLICATIONS, 12, 1, 5-23, English, 1063-293X, WOS:000220660200001 - A MAS Framework for Models, Solutions and Tools Integration in Computer Network-Oriented CE Environment

YUKI Hironobu; ISHIKAWA Haruo; TADA Shin-ichirou; NAKANO Shizuka
This paper describes the application of neural network for nano-indentation testing to evaluate mechanical properties of multi-layered thin films. The properties of films are evaluated from a set of load-depth curves which is obtained by indentation using spherical indenters having different radii. In this study, finite element simulation of indentation is conducted to provide learning data of the network. Two multi-layered networks are independently used to identify the properties of films. By using the first network, the ranges of estimation are roughly estimated, and the appropriate properties can be determined by the second network. It is demonstrated that Young's moduli of 4-layered films can be successfully determined by the proposed method. It is also shown that both of Young's modulus and thickness can be identified 2-layered films., The Japan Society of Mechanical Engineers, 2002, Transactions of the Japan Society of Mechanical Engineers Series B, 68, 666, 237-243, Japanese, 0387-5008, 110002370068, AN0018742X - 3次元CADシステムにおける設計意図に基づく形状モデリング

A method to determine the distribution of stresses and displacements in an infinite, linear, elastic, multi-layered medium subjected to static axisymmetric loading is presented in this work. By using axisymmetric governing equations, Hankel's transform and matrix analysis, the methodology gives a clearly arranged way to calculate the stresses and displacements in the medium. A numerical method for Hankel's transform is employed to perform the calculation. Two representative examples are studied.

This research focuses on the development of an intelligent CAD (ICAD) system called ConCAD for implementing concurrent engineering design. The functional requirements for future ICAD system are reviewed and discussed from literature survey, and a unified system architecture is proposed, and also a new data structure for representing solid model is employed.

This paper presents the development of an integrated programming environment, so called ANetCoDE, for implementing ConCAD system. ANetCoDE is a hybrid agent-oriented programming environment to support the implementation of design agents that can harmonize the deliberative characteristics with the reactive characteristics of agents. The representation techniques for design agents are proposed to be able to accommodate their internal state to the continuously changed design states. With the ANetCoDE, the design agents supporting multidisciplinary design activities are effectively designed and run well in a dynamic design environment., The Japan Society of Mechanical Engineers, 2001, 日本機械学会第10回設計工学・システム部門講演会講演論文集, 2001, 00-34, 154-157, English, 1348-0286, 110002481131, AA11901475 - 設計支援のため三次元CADシステムに関する考察

1998, Materials Science Research International, 4, 3, 171-178 - Analysis of an internal central crack with bridging fibers in a finite orthotropic plate
M Ji; H Ishikawa
An elastic analysis of an internal central crack with bridging fibers in a finite orthotropic elastic plate is carried out. A model of pull-out of fiber is applied to the bridging fibers of the crack. The boundary collocation method (BCM) is presented for analyzing the distributions of stress and displacement of the finite orthotropic plate with the internal central crack under the loading conditions of an applied uniform tension stress and the traction forces on crack surfaces yielded by the fiber pull-out model. For the crack tip stress intensity, besides the usual factor F for finite correction, the other two new parameters, the bridging influence factor B-K and the finite bridging correction factor F-b, are defined. Finally, for an example problem, the present numerical results are compared with those obtained by FEM for the same finite orthotropic plate and those obtained by the solution for infinite orthotropic plate.

M Ji; H Ishikawa; M Anahara; Y Yasui
The degree of the enhancement of the fracture resistance of an orthogonal three-dimensional composite of cabon fiber reinforced epoxy is experimentally determined using a DCB testing method. By analyzing the load-displacement curve and the energy change caused by the breaking of the bridging fiber yarn, the mechanism of the enhancement of the bridging fiber for the fracture resistance is considered. It was found that the greater the number of bridging yarns in the crack, the greater is the amount of deformation energy per cracking area necessary for crack propagation. An estimation method for the mode I fracture toughness of the material is presented., JAPAN SOC MECHANICAL ENGINEERS, Jan. 1997, JSME INTERNATIONAL JOURNAL SERIES A-SOLID MECHANICS AND MATERIAL ENGINEERING, 40, 1, 37-43, English, 1340-8046, WOS:A1997WK04300006 - The estimation of fracture resistance of orthogonal three-dimensional fiber-reinforced composite by DCB testing

JI Ming; ISHIKAWA Haruo
An analysis of a crack with bridging fibers in an orthotropic elastic infinite plate is carried out. Based on Lekhnitskii's anisotropic elastic theory, the distributions of the stress and the displacement of the orthotropic elastic infinite plate with a crack are analyzed under a uniform remote tension stress. As well as utilizing the model of fiber pull-out, the relationship between the traction force at a bridging fiber and the crack opening displacement is established. The stress intensity factor KI and the strain energy release rate GI of the crack are obtained by linear elastic fracture mechanics, and the influence factor BK of the bridging for the stress intensity is defined. Finally, in order to discuss the effectiveness of the present method, an example problem, the finite element method solution of which was given, is numerically solved., The Japan Society of Mechanical Engineers, 1996, Transactions of the Japan Society of Mechanical Engineers Series B, 62, 593, 26-31, Japanese, 0387-5008, 110002372563, AN0018742X - The Estimation of Fracture Resistance of Orthogonal Three-Dimensional Fiber-Reinforced Composite by DCB Testing

TAKAHASHI Hideo; ISHIKAWA Haruo
Sometimes, holes at the bottom land of gears are made for lubrication of gear systems, such as gears in manual transmission where a needle bearing is used between the gear and shaft. In the present study, a pair of spur gears with holes at the bottom land is analyzed by a three-dimensional finite-element method. The distributions of the tooth root stress and the tangential stress at the periphery of holes are obtained. The effects of the addendum modification coefficient, tooth width, number of holes and hole position along the tooth width on the distributions are investigated under the loading condition of a concentrated force and two kinds of gearing with uniform and partial contacts. Some of the numerical results are experimentally confirmed by the stress measurment., The Japan Society of Mechanical Engineers, 1995, Transactions of the Japan Society of Mechanical Engineers.
