Composing aspectual concerns with base concerns may raise conflicting situations that need to be identified and resolved. A conflict is detected whenever two or more concerns that contribute negatively to each other and have the same importance need to be composed together. This paper discusses the use of Multiple Criteria Decision Making (MCDM) methods to support aspectual conflict management ...

In the last few years, several Multi-criteria Decision Making (MCDM) methods have been proposed. One of these methods, known as TODIM (an acronym in Portuguese for Interative Multi-criteria Decision Making), has been extended to uncertain MCDM problems. Firstly, using fuzzy numbers and recently using intuitionistic fuzzy numbers. The recently developed intuitionistic fuzzy TODIM, for short, IFT...

Multi criteria decision making (MCDM) methods like analytic hierarchy process, ELECTRE and multi-attribute utility theory are critically studied. They have irregularities in terms of the reliability of ranking of the best alternatives. The Routing Decision Support (RDS) algorithm is trying to improve some of their deficiencies. This paper gives a mathematical verification that the RDS algorithm...

Abrasive Water Jet (AWJ); which may be accepted as a relatively new and nature-friendly technology for the industry, can simply be defined as the technological process that uses a transformation of the high-pressure jet to the high-speed waterjet as a tool for cutting substance, specially materials. As this technology has the ability of cutting some multicomponent materials in all directions, w...

  Multiple criteria decision making (MCDM) problem is one of the famous different kinds of decision making problems. In more cases in real situations, determining the exact values for MCDM problems is difficult or impossible. So, the values of alternatives with respect to the criteria or / and the values of criteria weights, are considered as fuzzy values (fuzzy numbers). In such conditions, th...

Multicriterion decision making (MCDM) has emerged as an effective methodology due to its ability to combine quantitative and qualitative criteria for selection of the best alternative. Concurrently, fuzzy logic is gaining importance due to its flexibility in handling imprecise subjective data. In the present study two fuzzy logic-based MCDM methods, namely similarity analysis (SA) and decision ...

This feature cluster of the European Journal of Operational Research is one of three special issues devoted to results from the Sixteenth International Conference on Multi-Criteria Decision Making held at Semmering, Austria, on February 18–22, 2002. The special issue of the Journal of MultiCriteria Decision Making edited by Matthias Ehrgott and Mikulas Luptacik will focus on application-oriente...

The selection of a strategy to seismically upgrade an existing building is a difficult problem. In fact, several different technologies are available to this aim nowadays. Furthermore, many generally conflicting options have to be considered to assess the performance of each alternative. Decision support systems like the socalled multi-criteria decision-making (MCDM) methods may be useful in ma...
