TL;DR: In this article, the theoretical foundations of the traditional modeling approaches are questioned using phenomenology and hermeneutics as philosophical base, exposing the difference between the remodelling of some existing models, the modelling of physical objects and the modeling of psychical, intentional objects.

TL;DR: An approach based on an intermediate topological level with a dynamic space ordering (dso) heuristic for space layout planning is presented, and the enumeration time has been reduced.

TL;DR: A new fuzzy controller based on the SIRMs (Single Input Rule Modules) dynamically connected fuzzy inference model stabilizes series-type double inverted pendulum systems of different parameter values in about 10.0 s for a wide range of the initial angles.

TL;DR: A structured method for developing a conceptual data model by starting from a functional model expressed in a natural language, and developing an augmented transition network (ATN) parser to develop conceptual dependency diagrams from natural language descriptions.

TL;DR: The ease with which the knowledge is acquired and maintained using RDR, the use of a dynamic design ontology and the automatic generation of conceptual models using FCA allows for the continual evolution of the KBS in keeping with the notion that knowledge is continually evolving and ‘made-up’ to fit the situation.

TL;DR: An object model where classes are used to capture design standards and requirements relevant to designed objects is defined where the semantics of the resulting object model are defined and the axioms that define its consistency are formulated.

TL;DR: A stochastic optimization model is developed and a Monte Carlo and genetic algorithm based method is presented to solve the problem of building optimally coordinated bidding strategies for competitive suppliers in energy and spinning reserve markets.

TL;DR: The augmented-type network is proposed that includes several basic modules intelligently affiliated according to traffic characteristics on the freeway that indicates very encouraging achievements when the proposed neural network model is employed to govern the freeway traffic operations.

TL;DR: A Fuzzy–Rough Estimator of Algae Populations (FuREAP), a hybrid system involving FuzzY Set and Rough Set theories that estimates the size of algae populations given certain water characteristics, is proposed.

TL;DR: A knowledge-level model of an individual designer as an agent is described, in which reflective reasoning about elements of situatedness, and reasoning from the point of view of other participants, are explicitly modelled.

TL;DR: A classifier system, implementing an instance-based reinforcement-learning scheme, is used for the sensory-motor control of an eight-legged mobile robot and for the synthesis of the robot gaits, and the proposed self-organized system is tested.

TL;DR: A concept of novel self-reconfigurable robotic system made of homogeneous autonomous robotic modules which can metamorphose into arbitrary configuration according to the surrounding environment or desired specification is presented.

TL;DR: The Bernstein basis function (BBF) network described in this paper is a novel neural network approach to performing functional approximation tasks such as curve and surface fitting and a simulation study and real world experiment are presented to show the effectiveness.

TL;DR: A new approach is needed to represent and maintain vague geometric information and such an approach is presented in this paper.

TL;DR: A new time-series predication method based on pattern analysis that has advantages over existing methods in some applications is proposed and carried out.

TL;DR: It is illustrated how software engineers developing engineering design systems can introduce patterns into the conceptual modeling techniques that were developed in the database community and integrate them with techniques that are emerging in the object-oriented analysis and engineering design community to raise the level of abstraction used to communicate software specifications and to build applications.

TL;DR: A neural-fuzzy model, which is characterized by its ability to suggest the appropriate change of process parameters in a relatively complex parameter-based control situation involving multiple parameters, is presented.

TL;DR: A method by which human dynamic interactions with the externally provided tasks can be simulated and applied to the analysis of the high-tech aircraft accident that occurred in Columbia in 1995, which is a well-known accident caused by the discoordination between the human and the automated aircraft.

TL;DR: A novel application of Taguchi method to systematically tune the weights of a radial basis function (RBF) network, which is widely used for modelling vaguely defined but smooth nonlinear functions, is presented.

TL;DR: A number of conceptual issues in component-assembly modelling are presented and their possible solutions are presented.
