This paper discusses the possible uses of the VIP (Variable Interdependent Parameters) Analysis software and methodology in negotiation support. VIP Analysis is a decision support tool that incorporates complementary approaches to deal with the aggregation of multi-criteria performances under imprecise information. Its purpose is to support the evaluation of a discrete set of alternatives according to multi-attribute additive value functions. We propose extensions of the methodology of VIP Analysis to address explicitly the differences among the actors in terms of the weights space.

“…In the 100-factor solution, 21 factors are related to MCDM applications. These applications cover not only traditional application areas, such as asset management [24], scheduling problem [25], assignment problem [26], questionnaire survey [27], credit scoring [28,29,30,31], and risk evaluation [32,33,34]; but also emerging novel areas, such as verbal data classification [35], Web-based decision support [36], habitual domains [37], electronic commerce systems [38,39], and e-participation [40]. The second trend is that MCDM has entered into some new research areas [41].…”

It is a challenge task to discover major topics from text, which provide a better understanding of the whole corpus and can be regarded as a text categorization problem. The goal of this paper is to apply latent semantic analysis (LSA) approach to extract common factors that representing concepts hidden in a large group of text. LSA involves three steps: the first step is to set up a term-document matrix; the second step is to transform the term frequencies into a term-document matrix using various weighting schemes; the third step performs singular value decomposition (SVD) on the matrix to reduce the dimensionality. The reduced-order SVD is the best k-dimensional approximation to the original matrix. The experiment uses more than fifteen hundreds research paper abstracts from a specific field. Because different factor solutions of the LSA suggest different levels of aggregation, this work examines thirteen solutions in the experiment. The results show that LSA is able to identify not only principle categories, but also major themes contained in the text.

“…Smart Swaps is the software for the implementation of even swaps (Hämäläinen, 2003). This program helps the decision-maker with even swaps offering suggestions for alternatives that present practical dominance and presenting the attributes that can be candidates for the next swap, avoiding the need for the decision-maker to study the method in detail before applying it (Mustajoki & Hämäläinen, 2005).…”

ABSTRACT. The aim of this article is to present, through a real case, a practical way, based on Multicriteria Decision Aiding, to support decision making in Plastic Surgery. The case studied was a Caucasian woman of 36 years of age with mammarian hypertrophia with ptosis and abdominal lipodystrophy, making it necessary to select the most adequate techniques for the best aesthetic result. For this purpose, the multicriteria methods Even Swaps and PrOACT were used. Three plastic surgeons working in the city of Rio de Janeiro with equivalent professional experience were consulted as decision agents. In order to define the objectives to be achieved, the criteria relevant to the making of the decision and the alternatives which could be used were identified. Throughout this identification and in the later analysis the surgeons participated in the application of the methods, which contributed towards facilitating their acceptance of the multicriteria analysis in their decision making. It was confirmed, in this case study, that the use of Multicriteria Decision Aiding tends to make the medical decision more wide ranging and, above all, transparent. The plastic surgeons themselves validated the analysis, considering it fully consistent with their professional experience.
