Multicriteria decision‐making (MCDM) methods are concerned with the ranking of alternatives based on expert judgements made using a number of criteria. In the MCDM field, the distance‐based approach is one popular method for obtaining a final ranking. The technique for order preference by similarity to the ideal solution (TOPSIS) is a commonly used example of this kind of MCDM method. The TOPSIS ranks the alternatives with respect to their geometric distance from the positive and negative ideal solutions. Unfortunately, two reference points are often insufficient, especially for nonlinear problems. As a consequence of this situation, the final result ranking is prone to errors, including the rank reversals phenomenon. This study proposes a new distance‐based MCDM method: the characteristic objects method. In this approach, the preferences of each alternative are obtained on the basis of the distance from the nearest characteristic objects and their values. For this purpose, we have determined the domain and Fuzzy number set for all the considered criteria. The characteristic objects are obtained as the combination of the crisp values of all the Fuzzy numbers. The preference values of all the characteristic object are determined on the basis of the tournament method and the principle of indifference. Finally, the Fuzzy model is constructed and is used to calculate preference values of the alternatives, making it a multicriteria model that is free of rank reversal. The numerical example is used to illustrate the efficiency of the proposed method with respect to results from the TOPSIS method. The characteristic objects method results are more realistic than the TOPSIS results. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Multi‐criteria decision analysis presumes trade‐off between different criteria. As a result, the optimal solution is not unique and can be represented by the Pareto frontier in the objective space. Each Pareto solution is a compromise between different objectives. Despite a limited number of Pareto optimal solutions, the decision‐maker eventually has to choose only one option. Such a choice has to be made with the use of additional preferences not included in the original formulation of the optimization problem. The paper represents a new approach to an automatic ranking that can help the decision‐maker. In contrast to the other methodologies, the proposed method is based on the minimization of trade‐off between different Pareto solutions. To be realized, the approach presumes the existence of a well‐distributed Pareto set representing the entire Pareto frontier. In the paper, such a set is generated with the use of the directed search domain algorithm. The method is applied to a number of test cases and compared against two existing alternative approaches.  相似文献

A model‐based process is a methodological approach that facilitates interventions in new and ill or not structured problem situations. It is oriented towards improving the robustness of the intervention and its results in an incremental definition of both the problem formulation and the model, in order to reduce the uncertainty that is not only associated with the model parameters but also with the model structure, and sometimes also with the problem formulation. The nature and results of this approach, which consider the interaction between an analyst and the actors of the decision system as the decision aiding core, are proposed in relation to some actual interventions.  相似文献

Matching unfamiliar faces is highly error‐prone, and most studies highlight the implications for real‐world ID‐checking. Here we study a particular instance of ID‐checking: proof of age for buying restricted goods such as alcohol. In this case, checkers must establish that an identity document is carried by its legitimate owner (i.e., that the ID photo matches the face of the bearer) and that the ID proves the bearer to be old enough to make the purchase. Across three experiments, using two common forms of photo‐ID (i.e., driving licenses, PASS+ cards) we show that observers produce very high error rates when age requirements are met, but faces mismatch. This bias away from detecting a face mismatch remained evident in experienced cashiers—though to a somewhat attenuated level. We discuss interactions between face matching and other tasks, and the practical consequences of a bias which favours those using photo‐ID with fraudulent intent.  相似文献

Many everyday decisions have to be made under risk and can be interpreted as choices between gambles with different outcomes that are realized with specific probabilities. The underlying cognitive processes were investigated by testing six sets of hypotheses concerning choices, decision times, and information search derived from cumulative prospect theory, decision field theory, priority heuristic and parallel constraint satisfaction models. Our participants completed 40 decision tasks of two gambles with two non‐negative outcomes each. Information search was recorded using eye‐tracking technology. Results for choices, decision time, the amount of information searched for, fixation durations, the direction of the information search, and the distribution of fixations conflict with the prediction of the non‐compensatory priority heuristic and indicate that individuals use compensatory strategies. Choice proportions are well in line with the predictions of cumulative prospect theory. Process measures indicate that individuals thereby do not rely on deliberate calculations of weighted sums. Information integration processes seem to be better explained by models that partially rely on automatic processes such as decision field theory or parallel constraint satisfaction models.

Sometimes, individuals must choose between acting in a way that satisfies their own desire or acting in a way that satisfies their partner's desire. What are the consequences of choosing one over the other for individuals' well‐being and relationship? Using experience sampling data (934 reports by 106 participants) that assessed daily decision conflicts in relationships, we examined consequences of partner‐satisfying decisions. A higher proportion of partner‐satisfying decisions predicted more perceived needs fulfillment and marginally higher perceived relationship quality over the course of a week. Additionally, immediately after the partner‐satisfying decision, participants reported feeling closer to their partner, and reported more positive and less negative affect, even when controlling for the quality of the relationship.  相似文献

Early design is crucial for the success of the final product. In the conceptual design phase, several constraints, criteria, objectives and disciplines have to be considered. To this aim, multidisciplinary optimization has proven effective for the solution of engineering design problems, even in the industrial every‐day practice, to improve and simplify the work of designers in a successful quest of the best compromise solution. In this paper, a multicriteria decision‐making (MCDM)‐based design platform for early optimal design of industrial components is proposed. In a group decision‐making context, the selection of the most suitable component among several possible layouts is performed by means of a group Fuzzy Technique for Order of Preference by Similarity to Ideal Solution approach. Hence, a multi‐objective optimization is performed on the selected component by applying a multi‐objective particle swarm optimization for finding optimal component dimensions. An industrial case study is presented for showing the efficiency of the multicriteria decision‐making‐based design platform, regarding an innovative and low‐cost solution to increase the duration of heel tips in women's shoes.

Goal‐directed cognition is often discussed in terms of specialized memory structures like the “goal stack.” The goal‐activation model presented here analyzes goal‐directed cognition in terms of the general memory constructs of activation and associative priming. The model embodies three predictive constraints: (1) the interference level, which arises from residual memory for old goals; (1) the strengthening constraint, which makes predictions about time to encode a new goal; and (3) the priming constraint, which makes predictions about the role of cues in retrieving pending goals. These constraints are formulated algebraically and tested through simulation of latency and error data from the Tower of Hanoi, a means‐ends puzzle that depends heavily on suspension and resumption of goals. Implications of the model for understanding intention superiority, postcompletion error, and effects of task interruption are discussed.  相似文献

Human prosocial behaviors are supported by early‐emerging psychological processes that detect and fulfill the needs of others. However, little is known about the mechanisms that enable children to deliver benefits to others at costs to the self, which requires weighing other‐regarding and self‐serving preferences. We used an intertemporal choice paradigm to systematically study and compare these behaviors in 5‐year‐old children. Our results show that other‐benefiting and self‐benefiting behavior share a common decision‐making process that integrates delay and reward. Specifically, we found that children sought to minimize delay and maximize reward, and traded off delays against rewards, regardless of whether these rewards were for the children themselves or another child. However, we found that children were more willing to invest their time to benefit themselves than someone else. Together, these findings show that from childhood, other‐ and self‐serving decisions are supported by a general mechanism that flexibly integrates information about the magnitude of rewards, and the opportunity costs of pursuing them.

Zero is a special value in our daily lives, and previous research on how zero values affect decision making leaves many questions to be explored. The present research examined the zero effect in life‐saving decisions and found that people expressed strong preferences for options offering a possibility that no one will die, even when the expected loss was relatively high. The prominence effect (the notion that the option with possibly zero deaths is easy to defend and justify) was proposed as one possible explanation. Furthermore, we also found that the zero effect in these life‐saving decisions occurs only in loss framing rather than gain framing. We discuss the relationships between the zero effect, framing, and evaluation mode in life saving and other domains.  相似文献

Developmental research on Gestalt laws has previously revealed that, even as young as infancy, we are bound to group visual elements into unitary structures in accordance with a variety of organizational principles. Here, we focus on the developmental trajectory of both connection‐based and object‐based grouping, and investigate their impact on object formation in participants, aged 9–21 years old (N = 113), using a multiple‐object tracking paradigm. Results reveal a main effect of both age and grouping type, indicating that 9‐ to 21‐year‐olds are sensitive to both connection‐based and object‐based grouping interference, and tracking ability increases with age. In addition to its importance for typical development, these results provide an informative baseline to understand clinical aberrations in this regard.

Statement of contribution

What is already known on this subject?
  • The origin of the Gestalt principles is still an ongoing debate: Are they innate, learned over time, or both?
  • Developmental research has revealed how each Gestalt principle has its own trajectory and unique relationship to visual experience.
  • Both connectedness and object‐based grouping play an important role in object formation during childhood.
What does this study add?
  • The study identifies how sensitivity to connectedness and object‐based grouping evolves in individuals, aged 9–21 years old.
  • Using multiple‐object tracking, results reveal that the ability to track multiple objects increases with age.
  • These results provide an informative baseline to understand clinical aberrations in different types of grouping.

  • Extant research on family purchase behavior has focused almost exclusively on heterosexual couples. This exploratory study of non‐traditional households shows that lesbian couples are strongly egalitarian in decision behavior for a wide range of products and services. Perceptions about relative influence of each partner in these dyads are increasingly congruent as the decision process progresses. Findings demonstrate the inapplicability of two concepts long associated with family research, that is, power and relative resource theory, in lesbian couples. Instead, gender dynamics and equity play dominant roles in these relationships.

Organizational efforts of adopting, designing, and implementing work‐family policies converge into single, discretionary decisions of supervisors whether or not to ‘allow’ these policies to specific employees under their supervision. These decisions are referred to as allowance decisions. In order to close a theoretical gap in current work‐family literature, we present an integrated, conceptual model of managerial allowance decisions. We develop propositions regarding factors that influence a supervisor's allowance decision at three different levels of analysis and behavioural outcomes in employees. Building on organizational justice theory, moderating effects of employees' fairness perceptions of allowance decisions are discussed. Finally, we outline implications for future research and recommendations for managers in organizations.  相似文献

This paper examines the existence and consequences of consumers' position-based beliefs about product layouts. We propose that consumers believe that options placed in the center of a simultaneously presented array are the most popular. This belief translates into their choosing options placed in the center more often than those on the sides of a display: the center-stage effect (Studies 1 and 5). Results are driven by inferences of product popularity rather than higher levels of attention to products in a given position (Studies 2 and 3). The preference for middle options is accentuated when people explicitly take into account other people's preferences, increasing the need to choose a popular option (Study 3), but attenuated when layout-based information is not diagnostic (Study 4). Increasing the accessibility of own preferences for the intrinsic attributes about the products reduces the use of position-based beliefs to make judgments and attenuates the center-stage effect (Study 5). Theoretical implications for marketplace meta-cognitions, visual information processing, position effects, and the use of overall cognitive beliefs versus perceptual attention and memory-based individuating information to make judgments are discussed.  相似文献

In adults, decisions based on multisensory information can be faster and/or more accurate than those relying on a single sense. However, this finding varies significantly across development. Here we studied speeded responding to audio‐visual targets, a key multisensory function whose development remains unclear. We found that when judging the locations of targets, children aged 4 to 12 years and adults had faster and less variable response times given auditory and visual information together compared with either alone. Comparison of response time distributions with model predictions indicated that children at all ages were integrating (pooling) sensory information to make decisions but that both the overall speed and the efficiency of sensory integration improved with age. The evidence for pooling comes from comparison with the predictions of Miller's seminal ‘race model’, as well as with a major recent extension of this model and a comparable ‘pooling’ (coactivation) model. The findings and analyses can reconcile results from previous audio‐visual studies, in which infants showed speed gains exceeding race model predictions in a spatial orienting task (Neil et al., 2006) but children below 7 years did not in speeded reaction time tasks (e.g. Barutchu et al., 2009). Our results provide new evidence for early and sustained abilities to integrate visual and auditory signals for spatial localization from a young age.  相似文献

Choices are often identity-based but the linkage to identity is not necessarily explicit or obvious for a number of reasons. First, identities feel stable but are highly sensitive to situational cues. Second, identities include not only content but also readiness to act and to use procedures congruent with the identity. Third, identities can be subtly cued without conscious awareness. Fourth, what an accessible identity means is dynamically constructed in the particular context in which it is cued. Because identities carry action- and procedural-readiness, the outcome of an identity-based motivation process may be similar to or different from the choices an individual would have made in another setting. Moreover, once an identity is formed, action and procedural-readiness can be cued without conscious awareness or systematic processing, resulting in beneficial or iatrogenic outcomes.  相似文献
