This study focuses on developing the multicriteria collaborative filtering algorithm for improving the prediction accuracy. The approaches applied were user-item multirating matrix decomposition, the measurement of user similarity using cosine formula and multidimensional distance, individual criteria weight calculation, and rating prediction for the overall criteria by a combination approach. ...

This paper presents a state-of-the-art survey on multicriteria scheduling and introduces a definition of a multicriteria scheduling problem. It provides a framework that allows to tackle multicriteria scheduling problems, according to Decision Aid concepts. This problem is decomposed into three different problems. The first problem is about obtaining a model. The second one is how to take crite...

Intervals are related to the representation of uncertainty. In this sense, we introduce an integral of Gould type for an interval-valued multifunction relative to an interval-valued set multifunction, with respect to Guo and Zhang order relation. Classicaland specific properties of this new type of integral are established and several examples and applications from multicriteria decision making...

The considered models describe multicriteria decision making when the information provided from different criteria is given as fuzzy relations. These models differ according to the kind of the criteria weights and the aggregation procedures to fuse the fuzzy relations. The properties of aggregated fuzzy relation required to decide some multicriteria problem is discussed.

The paper analyses the application of multicriteria problem solving methods to design in the light of KLD0, a Knowledge Level theory of design. The pros and cons of three usual multicriteria decision rules applied to the resolution of incompleteness, inconsistency, imprecision, and ambiguity is discussed with the aid of a simple example.

In this paper, a new classification model which combines the discriminant analysis and the data envelopment analysis and bases on on the multicriteria decision making is developed. Our suggested model utilizes the relative efficiency concept of the data envelopment analysis in predicting group membership of units. The study is supported with an application which examines a few selected socioeco...

This work concerns a special class of multicriteria optimization problems, obtained from a given single-facility multicriteria planar location problem by adding several new cost functions. By means of a decomposition approach, based on the concept of Pareto reducibility, we have developed together with S. Alzorba and Chr. Günther an implementable algorithm for generating efficient solutions of ...

The paper describes combinatorial model-ing of decomposable systems: hierarchical system models, system components, design alternatives (DAs) for system components and their interconnection (Is), estimates of DAs and Is, changes of the systems. We point out some basic combinatorial operations: combinatorial description and presentation ; analysis and evaluation; revealing of bottlenecks by elem...

The services and communication facilities around the world are continuously increasing. This process of expansion of telecommunications infrastructure has enabled a new set of applications and systems that was previously impractical. Some of these systems, such as the standard ISDB-T (Integrated Services Digital Broadcasting Terrestrial) on which the Brazilian System of Digital TV (SBTVD) is ba...
