Fuzzy holons for intelligent multi-scale design in cloud-based design for configurations

Cloud-based design for configurations can be referred to as a service-oriented networked design for configurations model. However, cloud-based models also pose challenges such as reliability, availability, capability, ability, adaptability of resources, and services across spatial boundaries. Multi-scale design can presumably stimulate greater intelligence in cloud-based models. Using the concepts of the fuzzy holon and the fuzzy attractor, this paper proposes the fuzzy holonic approach to address multi-scale design for configurations. A fuzzy design holon is defined through two basic holons: fuzzy function holon and fuzzy solution holon. A fuzzy attractor is defined as a fuzzy function holon or fuzzy function solution toward which a design tends to evolve. The proposed fuzzy holon model is driven by two conflicting drives: (a) completeness of fuzzy function holons and fuzzy solution holons, and (b) discrimination of fuzzy function holons and fuzzy solution holons. Through simulations, four possible states of behavior of fuzzy holon design are found: (a) the impossibility state characterized by the impossibility of fuzzy holon creation; (b) the creation and destruction state sometimes characterized by the creation of fuzzy holons and sometimes the destruction of fuzzy holons, (c) the development state characterized by a natural creation and development of fuzzy holons and (d) the failure state characterized by the interruption of the development of the fuzzy design holon and the destruction of already created fuzzy design holon. The model explains that design is not an orderly and well behaved phenomenon. It shows that fuzzy holon design is a discontinuous phenomenon.Keywords Intelligent design · Cloud-based design and manufacturing · Cloud-based design for configuration · Multi scale design · Fuzzy holon design

The agent paradigm can be quite straightforwardly applied to handle complex uncertain problems where global knowledge is inherently distributed and shared by a number of agents, aiming to achieve a consensual solution in a collaborative way. In this context, the use of fuzzy agents, which implement design activity by means of fuzzy logic, is highly recommended due to the uncertain nature of design activity and design problems. In this paper, fuzzy agents are proposed to seek consensus in product configuration. This research set out to take a holistic view of the design for configurations and to integrate the consensus seeking in product configuration. A formal model based on the fuzzy set theory is used to represent the consensus. To define measures for consensus evaluation the concepts of intra and inter consensus design coefficients are also used. Consensual configuration, defined as consensus nucleus of configurations, emerges as the part or the fragment of configurations which receives the maximum degree of consensus. In the world of agents, the proposed approach considers consensus as the overlapping of perspectives of fuzzy agents. Fuzzy agents, their interactions and organizations are formalized and modeled to support this holistic view of designs for configurations. A.-J. Fougères and E.

The effective modelling of configurable products must handle the complex problem of representation of the configurable products, learning new configurable products and analysis of their behaviour. However, currently in advanced CAD systems, there exists no systematic and effective method for designing configurations and integrating behavioural aspects and simulations. This paper proposes and develops a grammar-based design approach to support both the computer-aided design for configuration and computing in CAD systems. Two interrelated questions are taken into account: (1) What are the hypothesis, properties and features for product configuration? (2) How can the product based on configuration features be represented and how can the configuration representation method integrate the numerical computing in design? This approach, under the guide of the proposed formal modelling, is implemented in computers. A design case study illustrates the proposed approach.
