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.

In this paper we consider decision problems that can be described as linear decision models. These models have been traditionally solved using linear programming, fuzzy linear programming, multiple-objective linear programming or ‘what-if’ analysis. Using these approaches, one encounters a number of difficulties. We propose an ‘evolutionary approach’ to overcome these difficulties. In the proposed approach the decision maker does not have to precisely specify the model (i.e. the objective functions, the RHS values, etc.) at the beginning of the solution procedure. In fact, the model evolves as the solution procedure proceeds. 相似文献

This article presents the vendor selection problem of the hydraulic pump division of a US original equipment manufacturing company. The division wants to identify appropriate vendors and allocate purchase orders among them while minimizing product acquisition costs and maximizing total product quality and delivery reliability. Visual interactive goal programming is used as a multi‐criteria decision analysis tool. Interaction with decision makers during the model building and solution process, and implications are discussed. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

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. 相似文献

This study addressed two questions concerning the interplay between adult romantic attachment and exposure to stressful circumstances: do stressful events predict fluctuation in romantic attachment during a period of unemployment, and does attachment measured at one point predict later changes in stressors? Stressors and attachment were measured over a six month period following involuntary job loss for a sample of 426 adults. Autoregressive models found evidence for both the stress-effects and stress-generation hypotheses, with more stressors associated with prospective decreases in attachment, and lower attachment associated with prospective increases in stressors. These findings support a more dynamic formulation of the interplay between attachment and exposure to stressors over the months following job loss. 相似文献

本研究采用行为反应时和事件相关电位(ERP)探讨道德的重量具身效应及“重量-道德”隐喻联结对该效应的调节作用。参考内隐联想测验的逻辑,采用联合分类反应任务,在默认的“重量-道德”隐喻表征情境(实验1)和道德垂直空间隐喻的启动情境(实验2)中,要求被试分别使用轻鼠标和重鼠标对道德/不道德词进行分类判断,考察鼠标重量对道德概念的加工所产生的影响。结果显示,在默认情境中,“重-道德,轻-不道德”的联合分类条件比“轻-道德,重-不道德”条件的分类反应时更短,并伴随有更大的脑电晚期正成分(LPC),而在启动道德垂直空间隐喻后,两种联合分类条件下的反应时和LPC结果出现反转。本研究结果表明道德概念的加工会受到重量经验的影响,“重量-道德”具身效应具有心理现实性,且重量概念与道德概念的隐喻联结引导并调节了这种具身效应。 相似文献

Some media have suggested that many youths who have previously completed a gender transition are “detransitioning”. Their experience is often framed around the idea of regrets but rare are the articles that provide a nuanced examination of their journey. This article presents the perspectives of youths who have detransitioned or discontinued a transition regarding their experiences and feelings on their journey from transition to detransition. Semi-structured interviews were conducted with 20 youths between the age of 16 and 25 years who were recruited on social media and who transitioned and detransitioned or discontinued their transition. Data were analysed according to thematic analysis. Regrets and feelings of satisfaction can both coexist. The processes of transition and discontinuation or detransition appear to be non-linear and participants do not necessarily return to a cisgender identity. Ambiguous loss theory is applied to frame youth experiences and feelings and to suggest way forward for intervention.
Highlights
- This paper examines the experiences and feelings of youth on their journey from transition to detransition.
- Their journey is experienced as non-linear, and often comprised mixed feelings and experiences about transition and detransition steps.
- Ambiguous loss theory allows a nuanced understanding of feelings and experiences of their journey from transition to detransition.
