Naive semantics to support automated database design

Research devoted to developing knowledge-based tools for database design has demonstrated that it is possible to encode a great deal of process knowledge about database design in a (knowledge-based) computer program. However, experience with these tools shows that the contribution of an expert human designer extends beyond his or her knowledge of database design techniques. The paper discusses the application of an approach, called Naive Semantics (NS), to simulate the contributions made to a design based on the designer's general knowledge. Naive semantics involves the use of an extensible store of generally understood knowledge about the world. The paper describes the types of information that could be included in a Naive Semantics knowledge base and how that knowledge might be applied to increase the effectiveness of automated database design systems. Results of various implementations of ontologies based on Naive Semantics are discussed     

A feature-based approach to structural design

Despite the continuing improvements in computeraided design (CAD) systems and improvements in geometric modeling, most CAD systems are used as advanced drafting and drawing management tools by structural designers. A computer model of a structural design usually is generated by creating a detailed geometric model of the primitive components of the design and then attaching attributes, such as physical properties and loading conditions, to the various geometric components to reveal the structural characteristics of those components. Thisbottom-up approach has been inherited from early drafting techniques and contrasts sharply with a structural designer's natural way of thinking and reasoning about the design. Geometric features, on the other hand, provide high-level abstractions of design information and can be tailored to a designer's specific engineering needs. In this paper the advantages of using feature-based techniques in structural CAD systems are discussed. These techniques provide better modeling primitives for users and superior data models for CAD systems for reasoning about the geometry, topology, and engineering properties of a structure.

DIS — Design integrated system

Analysis of the work of the chemical process designer has revealed that his activity - in essence, repeated synthesis such as analysis problem-solving - has its own structure so it may be regarded as a system. An attempt has been made to construct a modular computer programming system to support the process designer's work. The programming system's modules reflect nodal designing activity such as balancing, simulation, economic evaluation and optimization, and the necessary transfer of information from one design step to another is secured by integral communication between the modules. Particular attention has been paid to the development of a designer-machine interface to enable an easy dialogue with the programming system. Features of the Design Integrated System are shown by applying DIS to a simple but typical chemical process.     

Audioptimization: goal-based acoustic design

The authors present a new inverse, interactive approach to acoustic design that applies optimization techniques to an acoustic simulation system. For a new building, the system may suggest optimal configurations that would not otherwise be considered; for a hall with modifiable components or for a renovation project, it may assist in optimizing an existing configuration. Our system allows the designer to constrain changes to the environment and specify acoustic performance goals as a function of time. The constraints include the specification of a range of allowable materials as well as geometric modifications for surfaces in the hall. The designer also specifies goals for acoustic performance in space and time via high-level acoustic qualities such as decay time and sound level. Using this information, the system performs a constrained optimization of surface material and geometric parameters for a subset of elements in the environment. The system operates at varying accuracy levels, offering trade-offs between time and quality. Visualization tools facilitate an intuitive assessment of the complex time-dependent nature of sound, and they provide a means to express desired performance. By using optimization routines within an interactive application, our system reveals complex acoustic properties and steers the design process toward the designer's goals     

Direct talkback in computer supported tools for the conceptual stage of design

During the early stages of the design process, industrial designers are not working towards a clearly specified goal. They are exploring ranges of solutions, while at the same time adjusting and refining the definition of the design goals. In this phase, sketches and other visual material play a large role in supporting an internal dialogue in the designer. In this paper, we argue that this direct form of talkback is underemphasized in current computer-tools for the early stages of the design process.

We go on to show how direct talkback is implemented in a prototype of a designer's digital sketchbook, and share some of the results of using this prototype sketchbook for over a year in a designer's sketchbook. Finally, we discuss how some of the concepts, generated for the designer's digital sketchbook, can be generalised for broader applications.     

Optimal allocation in a multiresources graduated tariff communication environment

The shared expertise model for teaching interactive design assistants

The growing complexity of contemporary engineering designs requires the use of sophisticated computer-based design tools. Such tools increase productivity in drafting, configuration and calculations. However, the current generation of design tools plays a rather passive role in the entire design process. Recent progress in knowledge-based engineering design, machine learning and knowledge acquisition allows the development of knowledge-based design assistants which could behave as active partners to human designers, rather than as passive graphical or computational tools. This paper presents the shared expertise model (SEM) of interaction between a human designer and a knowledge-based design assistant, in which the design assistant behaves as an apprentice and a collaborator in the design process. The human designer and his computer-based assistant create designs together, with the assistant proposing routine or even innovative designs, and the human designer correcting and finalizing these design, as well as specifying creative designs. In this process, the assistant also learns from the human designer, constantly extending and improving its knowledge base, and becoming a better design assistant. This is achieved by employing apprenticeship multistrategy learning based on a plausible version space representation. Within the SEM framework, a human designer with limited programming capabilities can directly develop and maintain a personalized knowledge-based design assistant. The use of SEM leads to increased capabilities of the expert-assistant design team. In this paper, some of the main features of the SEM model, as well as its implementation with the Disciple toolkit, are illustrated within the domain of computer workstation configuration.

Intelligent approaches for generating assembly drawings from 3-D computer models of mechanical products

In order to reduce the time of mechanical product design and ensure the high quality of their assembly drawings, this paper develops an intelligent approach for generating assembly drawings automatically from three-dimensional (3-D) computer assembly models of mechanical products by simulating the experienced human designer's thinking mode with the aid of computer graphics and knowledge-based expert system. The key issues include the strategies and methods for selecting the necessary views in an assembly drawing, determining necessary sectional views in each view, eliminating the unreasonable projective overlap of the components in each view, and minimizing the numbers of both the views in an assembly drawing and the sectional views in each view. Based on the approach, corresponding software prototype was developed. Finally, it is demonstrated, from an example of the fixture in a modularized drilling machine, that its assembly drawing was generated successfully using this intelligent software prototype.
