A procedure has been developed to optimize designs of metal-clad post-frame buildings using an expert system. The novel part of the study is the development of a procedure that extends the solution of an engineering problem from a conventional algorithmic Computer Aided Design (CAD) program to be used by the knowledge base of an expert system. The expert system then uses this information to opt...

The current society can be associated with such terms as information and technology winners, expert systems, and ‘know-how’. While members’ active participation has been seen as important, neither the shift from information usage to information technology (IT) usage is fully understood, nor is the source of innovation. In this paper, a framework for studying grassroot innovating conditions is d...

This paper presents a VV&A solution to effectively address VV&A problems arising during the development of complex simulation systems. First, a VV&A process is presented along with the development of a computer support tool, HITVICE, which helps to organize and manage the different VV&A activities. Second, the optimal design method for VV&A schemes is presented to produce an optimal scheme, acc...

As intelligent tutoring system (ITS) issues are investigated and intelligent tutoring systems are developed, evaluation methodology becomes important. Basic researchers, system developers, and educators working with ITS all have motives for becoming involved in ITS evaluation. In formative evaluation, researchers examine a system under development, to identify problems and guide modifications. ...

Knowledge is receiving recognition as a strategic force in organizations. Correspondingly, one form of knowledge capture and maintenance organizations are tempted to use is expert system design by end users. The article discusses difficulties associated with end user development, both in terms of design quality and knowledge content. An analysis of 25 expert systems written by non-professional ...

Instruction may be seen as the intentional creation of conditions around learning so as to facilitate the achievement of determined goals. Normally, instruction is based upon certain educational strategies. It is well accepted that these strategies should be founded in a theoretical framework. However, the adoption of epistemological perspectives for the instructional design is not enough. It w...

EADOCS (Expert Assisted Design Of Composite Sandwich panels) is a multi-level and hybrid expert system for innovative conceptual design. The objectives for conceptual design support are to assess the feasibility and optimality of alternative solutions and to find the best concept for further detailed design. Case-based reasoning is applied to generate conceptual designs and to refine their stru...

This paper examines the need to provide a common interface to expert systems, simulation tools and CAD systems for architectural design. We observe that a large amount of information is duplicated in describing buildings to several different tools. We describe a frame based representation for building designs, and an interfacing mechanism to move information between various tools. We also exami...

It is widely recognized that today’s demands in mechanical power transmission systems, (MPTS), are characterized on the world wide basis by an increasing variety of system combinations . This calls for the development and use of computer programs for designing such systems quickly and accuratelly . An important reason for using computer aided design, (CAD) of integrated in the design of MPTS is...

Ultrasonic machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. This paper addresses the concept and development of an expert system (ES) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...
