摘要:

The engineering core curriculum typically represents those engineering science courses that are commonly taken by most engineering undergraduates. This project is intended to investigate whether improved learning is realized when students are taught engineering science Tram a design perspective. The design perspective requires that students understand how the ultimate product or service must achieve its engineering objective while satisfying certain economic goals

摘要:

This paper provides a comprehensive list of relevant books and articles pertaining to the subject area of “engineering design,” with specific focus on the methodology, education, economics, and management aspects of the design discipline. The purpose of this survey of engineering design literature is to provide a compendium of books and articles that may be instrumental in facilitating the process of sharing and disseminating design knowledge

摘要:

The traditional engineering design process ends too abruptly when economic or “nontechnic”factors must be considered. Leaving decisions about tradeoffs between cost and quality to marketing, accounting and management personnel has resulted in products that do not compete well in the usaional marketplace. Marketing personnel can determine customer preferences, but are poorly equipped to translate those preferences into product and manufacturing process specifications. Within a manufacturing company, engineers are the ones who possess the analytic capabilities required for true concurrent design decision making. This paper reviews our work on integrating decision analysis into the design process. We describe a method which will help engineers broaden the realm of their analysis to treat economic factors with the same respect they traditionally accord only to “technical” factors. Our approach is to integrate formal, mathematically rigorous methods for multiattribute utility decision-making witb conventional design analysis. We present a two-phased approach for preliminary design evaluation followed by fine-tuning for design optimization. An example of turnbuckle material selection and design illustrates the methodology

摘要:

Tolerance is an important aspect in comparing alternative designs and manufacturing processes. This paper presents a brief review of the previous work in the area of tolerance as it relates to manufacturing strategies and technologies. In addition, models for the economic selection of part tolerance that consider reworking are developed. The models can be helpful in augmenting some of the current artificial intelligence modules and expert systems to improve their performance.

摘要:

This paper presents a Real Tune Computer Aided Process Planning (RTCAPP) system which can serve as a support tool for economic decision making during design activities. The system is capable of providing the information about manufacturing implication of each added design feature to the designer during the design process of prismatic parts. A knowledge-based system using a bierarchical planning scheme and a multi-bank rule base is developed to generate near-optimal process plans in real time. The planning process is supported by an optimization module which uses dynamic programming to minimize manufacturing costs. The incremental planning mechanism utilizes as much of the existing plan information as is necessary to generate a new process plan, whenever the design is updated. The system serves as an effective concurrent engineering tool that can be used to provide real time feedback on the manufacturing cost consequences to the designer
