“…Research in this area has been mainly directed towards the definition of functions (Chandrasekaran and Josephson 2000), development of functional prototype schemes using function-behaviour-state (FBS) modelling (Umeda and Tomiyama 1997) and development of functional design methodologies using behaviour-driven function-environment-structure (B-FES) modelling framework Zhang, Tor, and Britton 2005). Recently, the assessment of materials at an early design stage has been in the spotlight, and more research has also been directed towards function-structure-material mapping in functional modelling (Deng and Zhu 2009). The 'input-output synthesis' approach has been used to develop a design language, called 'functional basis', where product function is characterised in a verb-object (function-flow) format to comprehensively describe the mechanical design space (Stone and Wood 2000;Hirtz et al 2002;Bohm, Stone, and Szykman 2005).…”

The systematic representation of design concepts is an important requirement for computational support during the conceptual design stage within the process of product development. Behavioural simulation of design concepts is used as a systematic representation framework, and behavioural representation is based on modelling and simulating the behaviour of a design artefact at the conceptual level to perform an overall function, leading to behaviour-based conceptual design. The behaviour-based conceptual design approach is critical for mechatronic systems since they require synergistic integration starting from the initial conceptual design phase. The present study is focused on behavioural representation and simulation of design concepts via discrete event system specification formalism and Petri Nets so as to contribute to systematic conceptual design in mechatronic systems. The paper introduces a representation framework for the behaviour-based conceptual design of mechatronic systems and its implementation on five selected case studies, among laboratory-level educational robots. In addition to Petri Net modelling and computer simulations, the implementation also includes physical simulations of the intended operational behaviours for educational robots on a distributed physical structure called the 'desktop design model'. In this paper, implementation on one of these case studies, namely the 'frog robot', is presented in detail.

“…It refers to that the output of a previous behavior is the driving input of a succeeding behavior. 7,8 Causal similarity is instanced as similarity in dependency of energy, materials and signals between connecting individual behaviors. Orderly function similarity: An orderly function similarity reflects that two behavioral processes have a same or similar order of functions delivered. For example, Figure 6 expresses the orderly function structure of the behavioral process, i.e.…”

“…Based on the FBS rationale, one of the authors of this paper and his partners introduced the environmental factor and established a ''function-environment-behaviorstructure'' (FEBS) model, for which a causal behavior process (CBP) was proposed. 7,8 In this paper, we shall further exploit behavior information in our study for design analysis and synthesis, including the research on a redesign framework and based on it an evaluation model for behavior similarity.…”

Functional adaptability makes a product not only multifunctional but also compact in structure and flexible in application. An adaptable-function mechanical product generally demonstrates various degrees of similarity in its behavioral processes for different adaptable functions. Evaluation of this similarity is an important aspect of research for the design of such products, especially for redesigning existing products towards functional adaptability. Until present there lacks research on the design and development of this specific kind of products, including the work on the similarity evaluation of their behavioral processes. To address this problem, this paper investigates the functional and structural characteristics of adaptable-function products first. Based on this, by applying the function-behavior-structure design rationale, a redesign framework of mechanical product for functional adaptability was proposed, and the similarity characteristic of behavioral process was investigated, both on that of the behavior structure and that of behavior characteristics. Furthermore, the paper applied a fuzzy mathematics method for the evaluation of behavioral process similarity, for which a fuzzy comprehensive evaluation model was constructed and the corresponding evaluation method was proposed. Finally, a mini-combined machine tool with adaptable-functions was taken as an example to analyze the behavioral processes and to illustrate the proposed similarity evaluation procedure. The results demonstrated the feasibility and effectiveness of the proposed methodologies.

Evaluating whether a newly configured product can satisfy the customers' individual requirements or not is crucially important for the modular configuration design. Product performance prediction at the end of the configuration process can estimate the performance parameter values through the soft computing method instead of practical test experiments, which enables fast and accurate evaluation of configuration schemes. In this article, we propose a novel prediction approach based on the integration of grey relational analysis and support vector machine through discovering the knowledge from the historical configuration information. The implementation process of the prediction is established, and the procedure in applying the prediction to the configuration design is presented. There are three key steps to achieve performance prediction. First, the module parameters that affect the performance need to be reduced using the grey relational analysis method and then a module parameter reduction is generated. Second, the relationship between the reduced module parameters and the performance parameter is mined from the limited existing product data. A support vector machine model used for regression prediction is constituted. Third, when the values of the module parameter reduction are determined, the performance value of a newly configured product can be predicted by means of the support vector machine model. This methodology can ensure the performance prediction executed in a short period of time with a high degree of precision, even under the small-sample conditions. A design case of the plate electrostatic precipitator is studied to illustrate and demonstrate the feasibility of the proposed method.
