The key idea is to establish an automatic design system which can transform the user’s language needs into the product features in real-time. A rifle was taken as a research instance and soldiers were chosen as evaluation customers. The theory of fuzzy set and semantic difference are adopted to evaluate the relationship between user’s needs and product features as well as their alternatives. FAHP (fuzzy analytic hierarchy process) is utilized to judge the user’s satisfactory forms. This method can also be applied to other product form designs.展开更多

The relationships am ong the models and methods are shown in Fig.1. Fig.1 Relationships among optimization methods for MCThe methods for MC relate to both of product and process, also customized quanti ty and deepness. The methods for MC are integrated by the work in the paper, whi ch can help to understand and use MC better. The optimization and standardization of product is the key for MC. Increasing op timization breadth in product family can help to decrease the customization quan tity in every section of production process. Increasing optimization deepness in products family can help to move the CODCP backward in production process. At the same time, the optimization and standardization of product is the key to reduce cost of customized product. The optimization of the integration of pr oduct and process is the key to reduce lead time of customized product.展开更多

Product d escription had an important effect on realizing networked customization. From th is point of view, this paper firstly analyzed four requirements of adaptability, stability, conciseness and definitude that product description methods for netw orked customization must satisfy. According to these requirements, the paper com mented on current methods of product description, pointing out their advantages and disadvantages. As none of current methods could satisfy the four requirement s simultaneously, they were not fully applicable to networked customization. The n a plug-in based product description method was brought forward and discussed in detail. In this method, product description for networked customization w as abstracted as three component parts of basic description, basic feature and c ustomization feature. These parts had different characteristics. Basic descripti on was applicable to all products types. Basic feature was stable as concerning specific product type. Variants of certain product type all possessed identi cal basic features. Customization features were variable. Different combinations of customization features would give birth to different product variants. Apply ing object-oriented method, three standard product description plug-ins could be got by encapsulating these component parts. As "basic feature" and "customiza tion feature" plug-in had similar structures, they could be further abstracted as "feature" plug-in. When describing a type of product, a "basic description" plug-in would be instantiated firstly. Then according to product’s specific ch aracteristics, necessary number of "basic feature" and "customization feature" p lug-ins would be instantiated and appended, such as "color", "material", etc. E ach "basic feature" plug-in related to an instantiated "feature value" plug-in , while each "customization feature" plug-in related to one or multiple instant iated "feature value" plug-ins. Finally, "associate" and "exclude" relation ship should be specified among associated "customization feature" plug-ins. Thr ough appending and combining various plug-ins, this method was capable of descr ibing any type of product while meeting the four requirements simultaneously. Th is paper also gave an example to clarify the application of plug-in based produ ct description method. This example firstly described a kind of customizable TV provided by certain company. Then it showed how to describe an individual co nfiguration of this customizable TV in XML. Furthermore, suppose a consumer want ed to search for relevant information of a TV with game function, this example explained how to utilize XML query language to benefit consumer’s searching for product information. From analysis, we could draw the conclusion that plug -in based product description method was superior to current description method s and fully adapted to networked customization environment.展开更多

The foundations of MC production are standardization, seriation and normality of production, guiding thought of Concurrent Engineering (CE), ap plication of CAD/CAM technology and etc. And design methods of MC products are d esign for product family, modular design, parameterization CAD, variant design, design for manufacturing (DFM) and design by customers. Design for product famil y is a method that first to design a basic form of the product, and then to with draw variant parameters to become a variable product model, makes a family or a series of product design at the same time. Modular design is that based on produ ct function analysis of different function or the same function but different sp ecification within a certain scope, divides and designs out a series of function modular, and through selection and combination of the modular can make up diffe rent products. Parameterization CAD is a CAD method that has function of dimensi on drive. Variant design is a method that under circumstance of keeping principl e constant and construction similar or likeness, properly adjusts part of constr uction and design parameters to adapt design demands. DFM demands the designer t o consider problems that will appear in manufacture in the stage of design, and to avoid them through optimal design. And design by customers is guiding custome rs to design within the scope of production capacity of enterprise and optional items that enterprise has designed to satisfy their requirements of form, functi on and price. Among them modular design, parameterization CAD and variant design are key technology of design methods of MC products. And design by customers is a main characteristic of design of customization product, and an effective sale means also.展开更多

This WMADF allows designers to develop web -based computer aided programs in a systematic way during the collaborative mec hanical system design and analysis process. This system is based on an emerg ing web-based Content Management System (CMS) called eXtended Object Oriented P ortal System (XOOPS). Due to the Open Source Status of the XOOPS CMS, programs d eveloped with this framework can be further customized to satisfy the demands of the user. To introduce the use of this framework, this paper exams three differ ent types of mechanical design and analysis problems. First, a repetitive design consideration and calculation process is transferred into WMADF programs to gai n efficiency for wired collaborative team. Second, the considered product solid model is created directly through the use of XOOPS program and Microsoft Compone nt Object Model (COM) instances. To the end of the paper, an example linked with ANSYS is used to indicate the possible application of this framework.展开更多
