Action,inaction, and factors influencing perceived decision making

Two studies examined factors hypothesized to be related to the subjective perception of decision making. A total of 302 introductory psychology students read four hypothetical scenarios that varied on two dimensions: frequency of the behavior and whether the behavior was an action or an inaction (a 2 × 2 design). Subjects rated the scenarios on whether the actor made a decision. In Experiment 1, the frequency of behavior was unrelated to decision making. In addition, actions were given higher decision ratings than inactions in two scenarios, but lower ratings in the other two scenarios. In Experiment 2 the latter discrepancy was explained by ratings of whether the actor behaved thoughtfully rather than reflexively, in that these ratings mediated the action–decision rating relationship.

Participatory and multiobjective development of watercourse regulation—creation of regulation alternatives from stakeholders' preferences

Multicriteria decision analysis (MCDA) methods have been recently applied in many environmental problems. Major aims have been to structure and to analyse multifaceted and complex problems, to compare incommensurable impacts and to clarify the preference order of alternatives. Most MCDA tools concentrate on aiding the process of choice among alternatives. The choice usually occurs at the end of the decision‐making process, but MCDA tools can also assist earlier in the process. In this article, we present a new MCDA‐based method in order to create watercourse regulation alternatives, which meet the objectives of stakeholders. The method is comprised of three elements: (1) framework for the planning and learning process partly based on the Image Theory, (2) analysis and evaluation of ecological, social and economic impacts of regulation, and (3) visual interactive Excel implementation of value‐tree analysis (REGAIM‐model). We show how the method was applied in a complex watercourse regulation development project in Finland. Altogether 36 face‐to‐face computer‐aided interviews were undertaken with the REGAIM model with representatives of different stakeholder groups. We present the main results of the interviews and discuss how these interviews supported generation of new watercourse regulation alternatives. We also describe the advantages of the new approach in the participatory watercourse management, and discuss the applicability of Image Theory in the watercourse regulation context.

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.     

Towards statistical multicriteria decision modelling: a first approach

Many real life situations result from decisions taken by a very large number of decision makers. Among them, we may cite road traffic congestion, crowding during shopping, equity market behaviour, distribution of holiday destinations, etc. Furthermore, these decisions often depend on the optimisation of several conflicting criteria. In this paper, we introduce a new multicriteria tool based on Markov chains to model and manage these macroscopic phenomena. Finally, the road traffic congestion problem will be considered to illustrate the applicability of our approach. Copyright © 2003 John Wiley & Sons, Ltd.     

Inducing compensatory information processing through decision aids that facilitate effort reduction: an experimental assessment

This paper examines the role of computer‐based decision aids in reducing cognitive effort and therefore influencing strategy selection. It extends and complements the work reported in the behavioral decision theory literature on the role of effort and accuracy in choice tasks. The central proposition of the research is that if a decision aid makes a strategy that should lead to a more accurate outcome at least as easy to employ as a simpler, but less accurate, heuristic, then the use of a decision aid should induce that more accurate strategy and as a consequence improve decision quality. Otherwise, a decision aid may only influence decision‐making efficiency. This occurs because decision makers use a decision aid in such a way as to minimize their overall level of effort expenditure. Results from a laboratory experiment support this proposition. When a more accurate normative strategy is made less effortful to use, it is used. This result is consistent with the findings of our prior studies, but more clearly demonstrates that decision aids can induce the use of normatively oriented strategies. The key to inducing these strategies is to make the normative strategy easier to execute than competing alternative strategies. Copyright © 2000 John Wiley & Sons, Ltd.     

On Modal Logics Characterized by Models with Relative Accessibility Relations: Part II

This work is divided in two papers (Part I and Part II). In Part I, we introduced the class of Rare-logics for which the set of terms indexing the modal operators are hierarchized in two levels: the set of Boolean terms and the set of terms built upon the set of Boolean terms. By investigating different algebraic properties satisfied by the models of the Rare-logics, reductions for decidability were established by faithfully translating the Rare-logics into more standard modal logics (some of them contain the universal modal operator).In Part II, we push forward the results from Part I. For Rare-logics with nominals (present at the level of formulae and at the level of modal expressions), we show that the constructions from Part I can be extended although it is technically more involved. We also characterize a class of standard modal logics for which the universal modal operator can be eliminated as far as satifiability is concerned. Although the previous results have a semantic flavour, we are also able to define proof systems for Rare-logics from existing proof systems for the corresponding standard modal logics. Last, but not least, decidability results for Rare-logics are established uniformly, in particular for information logics derived from rough set theory.Since this paper is the continuation of Part I, we do not recall here the definitions of Part I although we refer to them.

On the evaluation and application of different scales for quantifying pairwise comparisons in fuzzy sets

One of the most critical issues in many applications of fuzzy sets is the successful evaluation of membership values. A method based on pairwise comparisons provides an interesting way of evaluating membership values. That method was proposed by Saaty, almost 20 years ago, and since then has captured the interest of many researchers around the world. However, recent investigations reveal that the original scale may cause severe inconsistencies in many decision-making problems. Furthermore, exponential scales seem to be more natural for humans to use in many decision-making problems. In this paper two evaluative criteria are used to examine a total of 78 scales which can be derived from two widely used scales. The findings in this paper reveal that there is no single scale that can outperform all the other scales. Furthermore, the same findings indicate that a few scales are very efficient under certain conditions. Therefore, for a successful application of a pairwise-comparison-based method the appropriate scale needs to be selected and applied.

决策过程中的建议采纳

建议采纳是指决策者参考他人建议并形成最终决策的过程。在过去的20年中,建议采纳研究集中探讨了三方面问题：（1）评判者多大程度上采纳了他人建议;（2）他人建议对决策质量的提升作用;（3）建议者和评判者在决策中的信心。本文首先介绍了建议采纳研究的实验范式,并从测量方法和研究成果两方面对上述三个问题进行回顾。未来的研究应注意丰富“建议”的外延、关注“建议者”角色、拓展决策任务、并探讨情绪在建议采纳过程中的作用。
