Existing electronic shops based on CBR technology allow customers to search for adequate products by only specifying the attributes for the products in a fuzzy way. Unfortunately, most electronic shops do not further support customers after the retrieval step. However, especially con gurable products could be customized at this stage. Based on the approach of interactive adaptation operators, w...

In this paper an interactive approach to deal with fuzzy multiple objective linear programming problems is presented, which is based on the analysis of the decomposition of the parametric (weight) diagram into indifference regions corresponding to basic efficient solutions. This approach is illustrated to tackle uncertainty and imprecision associated with the coefficients of an input-output ene...

To better solve the complicated problem of multi-attribute group decision making (MAGDM), we proposed a systemic approach by extending TOPSIS method. Linguistic assess terms of each group member were translated into the matrix of fuzzy triangular numbers. By using the incomplete preference information, multi-steps interactive procedure was applied for evaluating, selecting, ranking and approxim...

The belief that the project manager, a person in charge of the project management (PM), plays a very important role to handle conflicting goals with the usage of all resources through the organization is without doubt. The main purpose of the project management is to minimize total project and crashing cost with the reference to both direct and indirect cost and other related constraints simult...

The development of an experimental environment with interactive features, suitable both for the reinforcement of undergraduate level teaching of control theory and also for graduate-level research work in the field of intelligent control is described. The students are prepared for the experiment by an interactive session on the Internet before coming into the laboratory. The hardware and the so...

Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network design model which aims to select the facilities and candidate links in a way that yi...

due to the explosive growth of the world-wide web, automatictext summarization has become an essential tool for web users. in this paperwe present a novel approach for creating text summaries. using fuzzy logicand word-net, our model extracts the most relevant sentences from an originaldocument. the approach utilizes fuzzy measures and inference on theextracted textual information from the docu...

Hesitant fuzzy sets (HFSs), which were generalized from fuzzy sets, constrain the membership degree of an element to be a set of possible values between zero and one; furthermore if two or more decision-makers select the same value, it is only counted once. However, a situation where the evaluation value is repeated several times differs from one where the value appears only once. Multiset hesi...

Our study falls under the perspective which aims at optimizing the quality of decision brought to the spacetime decision-making process. Our aim is to claim with an extensible, generic, deterministic and multicriterion model based on the axiomatic of models representing decision strategies and authorizing interaction between criteria. The suggested approach is constructive, interactive and base...

The paper presents an experimental toolkit for modeling and solving Cuuy constraint satisfaction problems (FCSPs) called JFSolver. JFSolver is a Java based library developed as an extension of a erisp constraint programming library to provide an enhanced functionality for handling fuzzy constraints including fuzzy constraint specification, propagation and search mechanisms. JFSolver comprises a...
