Flexible widget layout with fuzzy constraint satisfaction
2008 IEEE Conference on Soft Computing in Industrial Applications, 2008We propose a new solution for the flexible widget layout (FWL) problem, formulating this problem as a fuzzy constraint satisfaction problem (FCSP) in the field of artificial intelligence. Widget layout performed by computers is one of the most important challenges for automatic generation of graphical user interfaces (GUIs). In the field of model-based

On Considering Constraints of Different Importance in Fuzzy Constraint Satisfaction Problems
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1998Several real-world applications (e.g., scheduling, configuration, …) can be formulated as Constraint Satisfaction Problems (CSP). In these cases, a set of variables have to be settled to a value with the requirement that they satisfy a set of constraints. Classical CSPs are defined only by means of crisp (Boolean) constraints.

A fuzzy constraint satisfaction system for design and manufacturing
Proceedings of IEEE 5th International Fuzzy Systems, 2002We present an interactive constraint satisfaction system for design and manufacturing that supports modeling using fuzzy linguistic variables, terms and operators, fuzzy variables, numbers and operators, and crisp variables, numbers and operators. Constraint propagation is omni-directional and is achieved through value propagation based upon a formal ...

A distributed fuzzy constraint satisfaction system with context-based reasoning
International Journal of Human-Computer Studies, 1998This paper presents a fuzzy constraint satisfaction system which can be used in a distributive environment and, through an example, identifies contexts which exist within the constraint satisfaction system. The fuzzy constraint satisfaction system utilizes value propagation on constraints through the use of formal logic and theorem proving.

Automated Negotiation Nased on Prioritised Fuzzy Constraint Satisfaction Problem
2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008Automated negotiation is one of the key issues in e-commerce. For the purpose of better expressing Agent's requirement and preference, easier dealing with issues inter-dependence and trade-off, this paper analyze fuzzy constraints' significances to e-commerce negotiation detailedly, then proposed a general automated negotiation model based on ...

Solving constraint satisfaction and optimization problems by a neuro-fuzzy approach
IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 1999The solution of constrained satisfaction and constrained optimization problems using a Hopfield model requires determination of the values of a certain number of coefficients linked to the surrounding conditions of the problem. It is quite difficult to determine these values, mainly because a heuristic search is necessary.

FUZZY LINEAR PROGRAMMING WITH GRADES OF SATISFACTION IN CONSTRAINTS
2009We present a new model and a new approach for solving fuzzy linear programming (FLP) problems with various utilities for the satisfaction of the fuzzy constraints. The model, constructed as a multi-objective linear programming problem, provides flexibility for the decision maker (DM), and allows for the assignment of distinct weights to the constraints

Fuzzy linear programming with grade of satisfaction in each constraint
Proceedings of 1995 IEEE International Conference on Fuzzy Systems. The International Joint Conference of the Fourth IEEE International Conference on Fuzzy Systems and The Second International Fuzzy Engineering Symposium, 2002The authors introduce and modify a method for fuzzy linear programming (FLP) in which each constraint has a different grade of satisfaction. The FLP problem dealt with in the paper has fuzzy coefficients in its constraints. The fuzzy constraints can be expressed by four feasibility indices introduced by Dubois (1987) derived from four ranking indices ...

A New Axiomatic Framework for Prioritized Fuzzy Constraint Satisfaction Problems
2000The paper introduces an axiomatic framework for prioritized fuzzy constraint satisfaction problems (PFCSPs), in which the notion of global satisfaction degree is based on three intuitive axioms. First, if a constraint with the highest priority in a PFCSP is completely violated by a variable assignment, the variable assignment cannot be a solution to ...
