Relative importance of criteria: a quantitative approach

A mathematical definition for the assertion ‘a group of criteria A is more important than a group of criteria B’ is introduced. It is shown how quantitative information on relative importance of criteria allows us to obtain a more precise upper estimate for a set of all non-dominated solutions than the well-known Pareto set. © 1997 John Wiley & Sons, Ltd.     

On Variant Selection Mechanisms in Interactive MCDA – Engineering versus Reverse Engineering

In the paper, we focus on the engineering and the reverse engineering paradigms in the context of multiple criteria decision analysis. We argue and demonstrate that if variant selection mechanisms are reverse engineered, they are simple and intuitive to understand, making multiple criteria decision analysis marketable to operational research practitioners. We present a reverse engineering scheme for variant selection mechanisms, and we illustrate its working with instructive examples. We also present some experience with that scheme gathered when teaching a multiple criteria decision analysis course to students. Copyright © 2015 John Wiley & Sons, Ltd.     

The European school of MCDA: Emergence,basic features and current works

Multiple-criteria decision analysis has evolved considerably since its birth during the 1960s. As part of this evolution, several schools of thought have developed emphasizing different techniques and, more generally, different attitudes as to the way of supporting or aiding decision making. One of these schools is now commonly referred to as the ‘European School’, its members being part of a European Working Group entitled ‘Multicriteria Aid for Decisions’. In the first part of this paper (Section 1) we follow a historical perspective in order to trace the emergence of the European School. Its distinctive features and main ideas are then outlined in Section 2. Finally we provide a general review of the current major research topics developed within this framework (Section 3).     

Attribute-value functions as global interpretations of attribute importance

In order to better understand decision maker’s perceptions of the importance of attributes, Goldstein (1990) differentiates between global and local interpretations of attribute importance. While the appreciation for the distinction is growing, research on the relationship between measures of global and local importance is inconclusive. We believe that these inconclusive findings are caused by operationalizing global attribute importance with single-point measures that implicitly assume that the global interpretation of attribute importance linearly depends on the relevant range of context-specific attribute levels. To address this, we propose to operationalize the global interpretation of attribute importance by estimating decision makers’ attribute-value functions. Two empirical studies demonstrate that the shape of attribute-value functions changes from concave to convex with global attribute importance. Furthermore, the steepness of these functions increases with global attribute importance while the diminishing sensitivity decreases. Finally, it is demonstrated that the inconclusive findings about the relationship between common, single-point measures of global and local attribute importance is driven by non-linearities in decision makers’ attribute-value functions. The results suggest great promise for future research on using decision makers’ attribute-value functions for measuring the importance of attributes.     

Navigation in multiobjective optimization methods

Building on previous work of the authors, this paper formally defines and reviews the first approach, referred to as navigation , towards a common understanding of search and decision‐making strategies to identify the most preferred solution among the Pareto set for a multiobjective optimization problem. In navigation methods, the decision maker interactively learns about the problem, whereas the decision support system learns about the preferences of the decision maker. This work introduces a detailed view on navigation leading to the identification of integral components and features. A number of different existing navigation methods are reviewed and characterized. Finally, an overview of applications involving navigation is given, and promising future research direction are discussed.     

The distortion of criteria after decision-making

The results of two experiments indicate that decision-makers separately distort their interpretations of decision criteria and evaluations of information in a manner that justifies their decisions. In Study 1, participants reported a yes/no decision either before or after they rated the applicable decision criterion and problem information. Participants distorted their criterion and information ratings more when they reported their decisions before, rather than after, they rated the decision criterion and problem information. Study 2 demonstrated that distortion of decision criterion ratings occurred after a decision had been made whereas distortion of information evaluations occurred during the process of reaching a decision. These results are consistent with a two-stage model of decision-making in which the distortion of decision criteria is distinct from the distortion of decision information.     

A parameter analysis method for the weight‐set to satisfy preference orders of alternatives in additive multi‐criteria value models

In the context of the additive multi‐criteria value model, this paper investigates how the set of criteria weights (weight‐set hereafter) can be determined according to the preference orders of alternatives given by the decision maker. A construction method is proposed for the weight‐set for different intervals of β, where β is a differential amount of value between the preference information on two alternatives. The results of this paper are important for sensitivity analysis in multi‐criteria decision making (MCDM) problems and multi‐criteria group decision analysis.

A Theoretical Framework for Analysing the Notion of Relative Importance of Criteria

Multiple-criteria decision aid almost always requires the use of weights, importance coefficients or even a hierarchy of criteria, veto thresholds, etc. These are importance parameters that are used to differentiate the role devoted to each criterion in the construction of comprehensive preferences. Many researchers have studied the problem of how to assign values to such parameters, but few of them have tried to analyse in detail what underlies the notion of importance of criteria and to give a clear formal definition of it. In this paper our purpose is to define a theoretical framework so as to analyse the notion of the importance of criteria under very general conditions. Within this framework it clearly appears that the importance of criteria is taken into account in very different ways in various aggregation procedures. This framework also allows us to shed new light on fundamental questions such as: Under what conditions is it possible to state that one criterion is more important than another? Are importance parameters of the various aggregation procedures dependent on or independent of the encoding of criteria? What are the links between the two concepts of the importance of criteria and the compensatoriness of preferences? This theoretical framework seems to us sufficiently general to ground further research in order to define theoretically valid elicitation methods for importance parameters.     

The relative importance of political skill dimensions for predicting managerial effectiveness

The present study uses relative weight analysis to garner support for the incremental validity of political skill over more traditional managerial skills for predicting managerial effectiveness and to help identify the underlying theoretical mechanisms driving this relationship. In addition, we explore boundary conditions, in terms of gender and organizational level, where political skill may be more or less critical. Using 199 middle- and upper-level managers enrolled in leadership development programmes and multisource data, the findings supported political skill’s incremental validity over more traditional measures of managerial skills for predicting managerial effectiveness. In addition, two of five political skill dimensions—image management and interpersonal influence—were significantly important predictors of managerial effectiveness, providing support for social influence theory as perhaps the best theoretical model for understanding the political skill-effectiveness relationship. Also, an individual’s gender and level in the organizational hierarchy had significant moderating effects on the relationship between three political skill dimensions and managerial effectiveness.     

Female face preference in 4-month-olds: The importance of hairline

At 3–4 months of age, infants respond to gender information in human faces. Specifically, young infants display a visual preference toward female over male faces. In three experiments, using a visual preference task, we investigated the role of hairline information in this bias. In Experiment 1, we presented male and female composite faces with similar hairstyles to 4-month-olds and observed a preference for female faces. In Experiment 2, the faces were presented, but in this instance, without hairline cues, and the preference was eliminated. In Experiment 3, using the same cropping to eliminate hairline cues, but with feminized female faces and masculinized male faces, infants’ preference toward female faces was still not in evidence. The findings show that hairline information is important in young infants’ preferential orientation toward female faces.

Evolution of multi‐criteria analysis: a scientometric analysis

The field of multi‐criteria analysis has known very important developments during the last 20 years, if one considers the very large amount of activities that it has generated and continues to generate (papers in journals, a dedicated journal, books, meetings, applications, …). Even if multi‐criteria analysis has reached some maturity, its future is subject to questions and debate among its researchers: what is the evolution of the field? What is its structure? Is it integrating new topics? In order to answer such questions at least partially, we have studied multi‐criteria analysis literature by means of the method of associated words (scientometric analysis) and the software ‘Leximappe’. All the abstracts of the papers which are relative to multi‐criteria analysis and are included in the bibliographic ABI‐INFORM database from 1985 to 1996 have been analysed. In this paper, we will present some results of this study. Copyright © 1999 John Wiley & Sons, Ltd.     

The importance of multiple exemplar instruction in the establishment of novel verbal behavior

According to traditional linguistic accounts language, and its generative nature, cannot be taught. From a behavior analytic perspective, language is like any other behavior; it is learned and amenable to change. Based upon Skinner's radical behavioral analysis of verbal behavior, specific procedures have been designed to promote novel verbal relations. However, despite the strength and utility of this approach, using behavioral principles to understand the generativity of language has been challenging. Dependent upon the specific theory (e.g., stimulus equivalence, relational frame theory, bidirectional naming) within the radical behavioral orientation, researchers arrange unique procedures to evaluate the variables responsible for this phenomenon. This paper presents the commonalities and differences of two procedures (i.e., multiple exemplar training, multiple exemplar instruction) with examples of research highlighting the use of both in producing generativity. Further, it describes how multiple exemplar instruction is independent from other procedures leading to this outcome, and concludes by providing recommendations for both research and practice.     

The relative importance of psychopathy-related traits in predicting impersonal sex and hostile masculinity

This paper reports the relative contributions of several facets of subclinical psychopathy (i.e., callous affect, erratic lifestyle, interpersonal manipulation), subclinical narcissism (i.e., entitlement, exploitation), and trait aggression (i.e., anger) to the prediction of four enduring attitudes towards women and sexual assault (i.e., hostility towards women, negative attitudes regarding women, sexual dominance, impersonal sex) and a behavioral indicator of an impersonal sexual behavior (i.e., number of one-night stands). Survey data were collected from 470 single men living in the Detroit Metropolitan area. The importance of personality traits varied as a function of the outcome with anger most predictive of hostility toward women; erratic lifestyle most predictive of impersonal sexual attitudes and behavior, and entitlement most predictive of sexual dominance and negative attitudes toward women. These outcome-specific findings are interpreted and directions for future research are discussed.     

A Bibliographic Survey of the Activities and International Nature of Multiple Criteria Decision Making

One of the fascinating things about multiple criteria decision making (MCDM) is the degree to which the contributions that have built the field have come from all over the world. In this paper the international nature of the authorships of the 1216 refereed journal articles published on MCDM between 1987 and 1992, and the journals in which they have appeared, is examined. Also, an analysis of the 217 books and 31 journal special issues that have been published on MCDM, and 143 conferences that have been held on MCDM since the inception of the field, is similarly conducted. The paper concludes with a conference organizer, author and special issue guest editor index.     

The appraisal process: Exploring the role of meaning,importance, control and coping in work stress

Recent reviews on occupational stress research suggests that if progress is to be made towards a better understanding of stress at work then researchers need to consider alternative methodologies and establish new frameworks. This paper takes up that challenge and using both quantitative and qualitative techniques attempts to explore the appraisal process individuals go through in determining stressful experiences. The meanings individuals give to events, their importance and individual levels of control all provide fruitful avenues for further research. Such variables provide new approaches to research and offer a potential for explanation far greater than the more traditional interactional models.     

Identity Importance and the Overreporting of Religious Service Attendance: Multiple Imputation of Religious Attendance Using the American Time Use Study and the General Social Survey

The difference between religious service attendance measured using conventional surveys and time diaries has been attributed to identity processes; a high level of religious identity importance may prompt overreporting on a survey question. This article tests the hypothesized role of identity importance as an individual determinant of overreporting and the result of socially desirable behavior. A time diary measure of attendance (from the American Time Use Study 2003–2008) is imputed for conventional survey data (from the General Social Survey 2002–2008) using the multiple imputation for multiple studies procedure ( Gelman, King, and Liu 1998a ). Logistic regression models predicting self‐reported attendance and overreported attendance are estimated using identity importance as a key covariate and controlling for demographic variables associated with attendance. Identity importance is a strong predictor of both self‐reported and overreported attendance. Attendance, while a biased measure of actual behavior, may be a good indicator of religiosity.
