Information Flow Model

Abstract The IFBMDA is an Information-Flow-Based model for Mechanical Design Automation. This paper first analyzes the mechanical design process from the views of design methodology and cognitive model. Then, two essential assumptions about mechanical design behavior are provided. Based on the analysis and fundamental assumptions, this paper thoroughly describes five submodels which constitute the automation model IFBMDA. They are Information Flow model, Knowledge Processing model, Non-monotonic Expansion Search model, Iterative Constraint Generation and Solution model and Design Process Stage model. Then, this paper also evaluates the model in both practical and theoretical aspects and shows that it is well-developed in both aspects. Finally, the perspective of further mechanical design automation research is outlined.

The Mathematical Model

Abstract As the complexity of mechanical design increases, due to larger size mathematical models, the need for rational design procedures also goes up. As shown elsewhere, dichromatic graphs have proven their value as tools for the algorithmic education of mechanical engineers. This paper analyzes the worth of such graphs as a means to achieve rational design solutions in complex industrial problems. The paper covers plant maintenance and research & development professional case studies. A real-life problem in electromechanical system reengineering is the first application example. Attention is also given in the paper on the partitioning of large problems, involving many variables and relations. The design of a planetary gear unit, with a three-digit number of elements in the mathematical model, is an example problem in this area. In addition, changes and extensions to the computational problem solving theory are included.

Growth And Change

This article explains the concept and various aspects of mechanical design automation (MDA). The use of computers for mechanical design is often referred to as MDA. Serious commercialization of computer graphics for design and drafting began in 1969 with the founding of Computervision and Application. The commercial market picked up significantly in 1975, when new 19-inch storage tube display terminals became readily available from Tektronix. These units could be used with minicomputers without custom interfaces, and they could display substantially larger drawings than the older, 11-inch units. The 1980s saw tremendous growth and change in mechanical design automation. While the predominant computer continued to be the 16-bit Digital PDP-11, there was growing interest in Digital’s 32-bit VAX 11 /780. Display products were starting their transition from Tektronix’s storage tube units to raster displays, with color raster just around the corner. The 1990s was a decade of constant movement for the MDA industry.

A quick look to the literature related to “Design” points out the fact that traditional fields are covered by a huge quantity of concepts and sub-topics dealing with various research fields. Some of these fields and related concepts are emerging and others are disappearing. The last two decades provided a large variations in the covered fields—probably because of the computers capacity and the knowledge sharing using the internet- We are convinced that is time now for a global understanding of the evolution of the related preoccupations in order to start a new phase that deals with the next guidelines issues in design. Many researchers and gurus have proposed evolution schemes from an epistemological point of view. However, we believe that we still need a pragmatic analysis of what have been done and what is going on now in the various publications that deals with design, conferences and journals. To do so, we present in this paper an approach that lies on the systematic analysis of the International Design Engineering Technical Conference (IDETC-ASME), the Design Conference, the Integrated Design and Manufacturing in Mechanical Engineering (IDMME) and the International Conference in Engineering Design (ICED). We also consider the major reviews and journals related to design such as Computer-Aided Design, Journal of mechanical design and many others. Our proposition, presents a global overview that shows the time-evolution of the topics, the density production, the emerging areas and concepts. We show then that some topics remain with a great interest and other are in a decreasing period. A specific study of what is going on within the Design Automation Conference is provided and an open discussion is started.
