Product design is often viewed as being a heterarchical and iterative process, possessing both systematic and chaotic qualities. However, a common denominator across all design activities is the access and utilization of information. In today's computer-aided design market, most of the available tools are narrowly focused on specific computational details for individual stages of design. Aids are needed to support information access and utilization during all stages of the design process. The application of human engineering and ergonomics data by designers is an increasingly challenging problem. Locating and understanding relevant information so that it can be applied to specific design issues is difficult given the abundance of existing and new data available. This is further complicated, in that the data are typically written to communicate research results to other human factors specialists. A new software product, Computer Aided Systems Human Engineering: Performance Visualization Subsystem (CASHE:PVS), is described which will assist the designer during the decision making process, maximizing creative and analytical abilities while minimizing costs due to design time and errors. The software contains several features to enhance the designer's ability to interpret and apply the human factors data available in the product. Phenomena descriptions in text, figures, and tables are combined with experiential information via simulations, animations, and audio. This provides the user a unique and rich understanding of human performance phenomena and how they relate to the design of new products.

Abstract The paper describes a belt design package which works from within a commercial Computer Aided Design and Drafting package (AutoCAD) environment and utilizes FORTRAN programs for design and selection of lowest weight components for the drive system. The components used in the process are available as stock items in U.S.A. The relevant information on these products is stored in commercial database management systems such as EXCEL and LOTUS 1-2-3. Output from the package consists of scaled drawing and tabular specifications.

Product Forms

The product form design activities involve a high degree of uncertainty and complexity and are therefore not easily formulated, coded and regularized. Consequently, very few of the computer-aided design approaches presented in the literature can support the conceptual form design tasks typically performed at the preliminary stages of a product’s development cycle. To enable designers to perform their design activities more objectively and efficiently, this paper combines the principles of fuzzy set theory, the shape-blending method and genetic algorithms to generate a knowledge-based approach for product form design based upon a database describing the relationships between different product forms and their corresponding perceptual image evaluations.

Aided Design

In converting task listings into multiple pages of documentation for job aids or training, the two major problems are deciding how much material should go on each page and how text and graphics should be laid out on the page. A questionnaire study was used to collect input from 14 human factors personnel in order to design algorithms for page splitting and page layout. From the rules or heuristics used for page splitting, an algorithm was devised that closely matched human page-splitting results. Layout of individual pages was automated with an algorithm based on the (significant) consensus among the subjects on questions of graphics positioning and label ordering. The two algorithms have been combined in a computer-aided design procedure that automatically pages task lists and lays out individual pages.

Hostile Environments

Although automation in manufacturing is by no means novel, only recently have such manifestations as increasing use of robots and CAD/CAM (Computer-Aided Design/Computer-Assisted Manufacturing) involved human factors scientists/practitioners. This panel session suggests how these can contribute to industrial productivity by examining and recommending suitable divisions of labor between automation and workers and ways to improve interactions between them. For the most part these considerations have been sadly lacking in both technical and popular discussions about industrial robots. Five panelist will approach them from two perspectives: actual human factors experience in industrial automation, including robotics, and applicable experience in closely related areas, such as the use of teleoperators in hostile environments (nuclear and battlefield).

Aided Design

The use in design, of knowledge and understanding of human thermal comfort, heat stress and cold stress, is often complex and time consuming. A computer based system (IBM-PC) was developed to allow human factors practitioners to assess and manipulate knowledge, data and simulations of human response to thermal environments, thus allowing computer aided design. A description of the system, its design and development and examples of its use are provided. The role of such systems in design and assessment should be considered by human factors practitioners.
