Decision making with linguistic information is a research hotspot now. This paper introduces a linguistic truth-valued concept lattice based on lattice-valued logic for dealing with decision making under uncertain linguistic information. For dealing with the different linguistic terms more formally, a unified set of linguistic terms is defined according to the features of linguistic terms, and this set is verified to be a bounded lattice and then to be a lattice implication algebra through the definitions of relevant operations on it. Based on the unified set of linguistic terms, a linguistic truth-valued formal context as the premise of linguistic truth-valued concept lattice is defined and the linguistic truth-valued decision method is provided.

This work focuses on the multi-objective scheduling of reentrant lines. Three algorithms are tested : our Lorenz - Non dominated Sorting Algorithm (LNSGA), the Strength Pareto Evolution Algorithm 2 (SPEA2) and the Multi-Objective Ant Colony System (MOACS). Numerous experiments on various configurations of the system are made and finally their efficiency are ordered following two measures.

The aim of this paper is to build a user profile according to his own perception. We focus on the dynamic construction of the profile, which will increase the satisfaction of the user by being more personalized and accommodated to his particular needs. We suggest two methods to define the perception and transform it into a profile;the first method is achieved by querying the user and getting answers, which will guide through the process of implementation of the profile;the second method is achieved by comparing different subjects and ending up by an appropriate choice. As a case study, we took the example of color perception. We rely on fuzzy logic to represent the different aspects of color and to formulate the questions and answers.

In this paper, we proposed a model for selection of the most suitable city for a new nuclear power plant in Turkey by using fuzzy analytical hierarchy process and fuzzy analytical network process due to linguistic terms. The implementation of the system is demonstrated by a problem having four stages of hierarchy which contains four criteria and twenty attributes. The study compares the fuzzy analytic hierarchy process and fuzzy analytic network process results.

Some preliminary classes have been developed in MATLAB to interface with the JET PPF system which stores the data elaborated after the discharge. These classes simplify the most common operations required during an interactive analysis and visualization of JET data, while keeping all the power of a full programming language. The first class is ppfs which given a shot number retrieves a list of all the main family (DDAs) related to that shot, the second is ddas which lists all the DTYPEs belonging to a DDA. The last two classes are used for retrieving the actual data and perform the most common operation, such as basic plotting slicing and arithmetic operation.

The Reference Point Method (RPM) is a very convenient technique for interactive analysis of the multiple criteria optimization problems. The interactive analysis is navigated with the commonly accepted control parameters expressing reference levels for the individual objective functions. The final scalarizing achievement function is built as the augmented max-min aggregation of partial achievements with respect to the given reference levels. In order to avoid inconsistencies caused by the regularization, the max-min solution may be regularized by the Ordered Weighted Averages (OWA) with monotonic weights which combines all the partial achievements allocating the largest weight to the worst achievement, the second largest weight to the second worst achievement, and so on. Further following the concept of the Weighted OWA (WOWA) the importance weighting of several achievements may be incorporated into the RPM. Such a WOWA RPM approach uses importance weights to affect achievement importance by rescaling accordingly its measure within the distribution of achievements rather than by straightforward rescaling of achievement values. The recent progress in optimization methods for ordered averages allows one to implement the WOWA RPM quite effectively as extension of the original constraints and criteria with simple linear inequalities.

Query evaluation improvement and association rules are two interesting research topics in data query and management. In this paper, the relations are decomposed with respect to the mined association rules, and several basic data query expressions are rewrote which have relatively less time cost. This is desirable for processing queries in an efficient manner.

We introduce a new generalization of the OWA operator called the induced linguistic generalized OWA (ILGOWA) operator. It is an extension that uses the main characteristics of three well-known aggregation operators: the IOWA, the LOWA and the GOWA operator. Therefore, in the same formulation, this operator uses linguistic information, generalized means and order inducing variables to reorder the arguments. Note that this generalization can be seen as a first step in the process of generalizing the LOWA operator with generalized means because other linguistic models can be considered. One of its main results is that it includes a wide range of linguistic aggregation operators such as the induced linguistic OWA (ILOWA), the induced linguistic OWG (ILOWG) and the linguistic generalized OWA (LGOWA). We further generalize the ILGOWA operator by using quasi-arithmetic means.

The paper briefly formulates the error loop as a tool for designing robust stability control systems in front of structured and unstructured uncertainties. In turn, the error loop formulation shows the main tool for accommodating such uncertainties is the noise estimator, which is the unique feedback channel from plant to control.
