“…The early Schemebuilder design workbench described in Bracewell et al (1993) and Sharpe et al (1993), has been enhanced so that schemes may be developed from first principles using a development of the function-means tree approach as described by Buur (1990). The process is facilitated by application of functionally classified working principles and bond graph based decomposition principles.…”

With increased pressures coming from global competition and requirements for greater innovation in product development, designers are hard pressed to deliver designs of higher quality and variety using a repertoire of technological options from different disciplines. This interdisciplinary product development approach has not only removed many of the traditional constraints to design but has now given designers a much wider freedom of choice as to the best solution to a design problem. The focus of this paper is a knowledge-based design environment called Schemebuilder, which is a comprehensive and integrated suite of software tools aimed at supporting the designer in the rapid development of product design models in the conceptual, through embodiment stages of design. Illustrated is the use of the software tools in the qualitative generation of alternative schemes, by application of stored working and decomposition principles in the development of a function-means tree-like information structure. With mechatronic product development as the main theme, this paper describes a closely integrated methodology that incorporates a bond graph approach to continuous-time energetic systems and high-level Petri nets for the rigorous description of discrete-time information systems. Additionally, a technique is suggested for the decomposition of free format statements of need into the rigorously defined design context and required functions, which form the starting point of the function-means development process.

“…Bond graphs [4][5][6][7] describe system energy variables through their bond elements by denoting effort variable flows in one direction and flow variable flows in the opposite direction which are decided by bond casual structure. It is, therefore, very easy to obtain the dynamic response of any energy variable from a bond graph simulation method.…”

Engineering design is a highly integrated and integrating process This two-part paper describes an integrated computer-based platform for the development from first principles of design solutions to appropriately defined need, and the choice and quantification of the best forms of embodiment This second paper (Part II) concentrates on the use of mathematical techniques based on sophisticated simulation and symbolic manipulation in the development and quantification of the conceptual schemes generated by the use of Artificial Intelligence The methods of selecting the best embodiments of the required functions are described, together with the means of determining the best size of component The use of function maps relating function to cost, weight, limits on strength, efficiency of operation, etc , are shown Finally, details are given of the use of automatically generated simulations of chosen embodied schemes These simulations are used to confirm expected performance and as part of the procedure for optimising the design

“…A generic representation (GR) across a wide variety of models that MLs could map into, and views could map out of, can make a difference. Graph data structures (GDS) can serve as GRs [12][13][14][15]. A GDS is simple, robust, scalable, and amenable to both relational and graph-theoretic algorithms.…”

We introduce the Concept→Model→Graph→View Cycle (CMGVC). The CMGVC facilitates coherent architecture analysis, reasoning, insight, and decision making based on conceptual models that are transformed into a generic, robust graph data structure (GDS). The GDS is then transformed into multiple views of the model, which inform stakeholders in various ways. This GDS-based approach decouples the view from the model and constitutes a powerful enhancement of model-based systems engineering (MBSE). The CMGVC applies the rigorous foundations of Category Theory, a mathematical framework of representations and transformations. We show that modeling languages are categories, drawing an analogy to programming languages. The CMGVC architecture is superior to direct transformations and language-coupled common representations. We demonstrate the CMGVC to transform a conceptual system architecture model built with the Object Process Modeling Language (OPM) into dual graphs and a stakeholder-informing matrix that stimulates system architecture insight.
