PB通用排序条件窗口的实现

在使用PB开发的应用程序中,经常需要对数据窗口中的数据进行排序。为满足用户对数据进行灵活排序的要求,笔者设计了一个通用的排序条件窗口w-sort,使用此窗口为父窗口,所有继承自此窗口的子窗口只需为一个数组赋值即可实现排序功能,使用极为方便。图一所示的是此排序条件窗口的一个子窗门的实例。在此窗口中,“可供选择的行”一栏列出了可供生成排序条件的行,每一行对应待排序的数据窗口中的一个字段。“已选择的行”一栏列出了用户已选择的行。用户通过拖放或者双击某一行的方法选择或是取消一行。当按<确定>按钮时,此窗口将向调用它的窗口返回一个排序条件字符串;如果用户按<取消>按钮,则返回一个空

Case-based parametric design system for test turntable

This paper presents a case-based parametric design system for test turntable. The aim of this system is to realize automatic and intelligent design of turntable. Utilizing the parametric design method, a knowledge-base composed of parameterized 3D product models is first constructed. All the corresponding design specifications or parameters are then saved in a data-base. Taking advantages of the CBR methodology, a most similar case can be easily retrieved from the pre-built design knowledge-base and case-base when a new design task comes. Only with a few revisions, the modified design can mostly satisfy the new design requirements to fulfill a new design and can be further saved as a new case into the database. The design system is built as a module embedded in Pro/ENGINNER 3.0. It contains a turntable case-base, a design knowledge-base, a CAD software and a graphic user interface. Now this system is on a trial operation in a ship institute, the result shows that it can enhance the design efficiency and reduce the design time and cost.     

Erklärende Designtheorie

Design, design research, and design science have received increasing attention lately. This has led to a more scientific focus on design that then has made it timely to reconsider our definitions of the design theory concept. Many scholars in Information Systems assume a design theory requires a complex and elaborate structure. While this structure has appeal for its completeness and complexity, it has led scholars to criticize simplicity and elegance in design science theories that fail to demonstrate the “required” elements. Such criticisms lead to questions about whether design theory can be considered theory at all. Based on a study of notable design writing in architecture, finance, management, cognitive psychology, computer science as well as information systems and the philosophy of science, the authors demonstrate that design theory consists of two parts: a design practice theory and an explanatory design theory. An explanatory design theory provides a functional explanation as to why a solution has certain components in terms of the requirements stated in the design. For explanatory design theory, only two elements are essentially necessary for a complete design theory: requirements and solution components. The argument is logical as well as empirical; the authors give examples of design theory drawing from IS as well as other design-related fields show how design theory can be both simple and complete. The paper concludes with a proposal for explanatory design theory.     

Text analysis for constructing design representations

An emerging model in concurrent product design and manufacturing is the federation of workgroups across traditional functional ‘silos’. Along with the benefits of this concurrency comes the complexity of sharing and accessing design information. The primary challenge in sharing design information across functional workgroups lies in reducing the complex expressions of associations between design elements. Collaborative design systems have addressed this problem from the perspective of formalizing a shared ontology or product model. We share the perspective that the design model and ontology are an expression of the ‘meaning’ of the design and provide a means by which information sharing in design may be achieved. However, in many design cases, formalizing an ontology before the design begins, establishing the knowledge sharing agreements or mapping out the design hierarchy is potentially more expensive than the design itself. This paper introduces a technique for inducing a representation of the design based upon the syntactic patterns contained in the corpus of design documents. The association between the design and the representation for the design is captured by basing the representation on terminological patterns at the design text. In the first stage, we create a ‘dictionary’ of noun-phrases found in the text corpus based upon a measurement of the content carrying power of the phrase. In the second stage, we cluster the words to discover inter-term dependencies and build a Bayesian belief network which describes a conceptual hierarchy specific to the domain of the design. We integrate the design document learning system with an agent-based collaborative design system for fetching design information based on our ‘smart drawings’ paradigm.

Customer-driven product design and evaluation method for collaborative design environments

Product concept generation and evaluation in a product development environment has been identified as the two major activities needed for obtaining an optimal design scheme. Product conceptual design is of critical importance in design through customer involvement for the systematic and simultaneous consideration on the impact of design decisions on manufacturing and assembly leads to repeated and excessive changes in design and processes. This paper introduces a novel knowledge support approach for the organization and ranking of design feature knowledge towards an integrated product model that incorporates a feature-based representation scheme targeted to evaluate the impact of design on subsequent activities in the conceptual design phase, taking into account the presence of design information and user preferences. An uncertain linguistic multi-attribute decision-making evaluation model is proposed and discussed for obtaining an optimal design scheme during the evaluation and selection of product design alternatives in conceptual design. The focus of this paper is on the development of a knowledge-intensive support design scheme and a comprehensive systematic fuzzy evaluation methodology for product conceptual design generation, evaluation, and selection. A case study and the corresponding scenario of knowledge support for design alternatives generation, evaluation and selection are provided for illustration.
