Abstract
In order to effectively reuse the design knowledge of product family life cycle development and support holistic and rapid individual product design, this article presents a new meta-model-based systemic customization design method for complex product systems within a product-pedigree. The proposed method aims to synthetically analyze the common and adaptive customer demands and product features of a product-pedigree of complex product systems and to quickly respond to the changing demands based on knowledge accumulation in the field of customization design. The key to implement such a method is (1) to construct a product-pedigree-oriented product meta-model with a four-layered architecture where it is possible to achieve a high degree of abstraction of product and (2) to develop a special technique for configuring the meta-model of the complex product systems. We have tested the proposed method with the rapid design of product-pedigree of a high-speed train’s bogies as an illustrative example. In this work, a rapid customization design prototype system has been developed and applied to the design of a high-speed train’s bogie to illustrate how to construct a product meta-model and how to conduct configuration design on different layers and variant design for generating new products.
Highlights
Complex product systems (CoPS) are high-tech integrated products, systems, or facilities including machinery, computer, electronic, material, and network communication fields, for example, aerospace system, ship, weapon and equipment, automobile, high-speed train, and other high-end equipment; they have the following characteristics: high cost, large scale, technically complex, single-piece or small-batch customization, and technology intensive.[1]
The typical customization design method is based on module combination and parametric design supported by a massive feature library, which is centered on twodimensional (2D) drawings or three-dimensional (3D) models, so it is difficult to integrate with design processes, standards, and experiences to form a normative innovative R&D paradigm.[4]
Based on the product-pedigree and meta-model, we propose a rapid customization design technology for CoPS based on configuration design and variants
Summary
Complex product systems (CoPS) are high-tech integrated products, systems, or facilities including machinery, computer, electronic, material, and network communication fields, for example, aerospace system, ship, weapon and equipment, automobile, high-speed train, and other high-end equipment; they have the following characteristics: high cost, large scale, technically complex, single-piece or small-batch customization, and technology intensive.[1]. The typical customization design method is based on module combination and parametric design supported by a massive feature library, which is centered on twodimensional (2D) drawings or three-dimensional (3D) models, so it is difficult to integrate with design processes, standards, and experiences to form a normative innovative R&D paradigm.[4] Product model is regarded as a basis for realizing knowledge reuse and sharing, which plays a core role in customization design.[5] Generally, designing a CoPS needs a long-term development process in a complex evolutionary way and products form a huge product spectrum. There are many common and adaptive technologies of CoPS and massive and constantly evolving knowledge, so it is difficult to develop a reasonable product model to support the customization design. We propose a meta-model-based systemic customization design method of CoPS to solve the above problems. 2. We propose a product-pedigree-oriented product meta-model construction technology of CoPS. 3. Based on the product-pedigree and meta-model, we propose a rapid customization design technology for CoPS based on configuration design and variants.
