A multiobjective decision support system for multiresource forest management

A multiobjective and/or multiperson decision support system for analyzing multiresource forest management problems is developed in this paper. The procedure includes formulating the problem in a multiobjective and group decision making framework, and solving it using two solution techniques which consist of a distance-based compromise programming (CP) and a cooperative game theoretic approach of the Nash equilibrium type. The problem consists of five forest resources management objective functions to be maximized. Solving the problem using the two solution techniques enables determining a satisfactory compromise solution of the five forest resource management objectives. Sensitivity analysis of the two techniques shows compromise programming to be more sensitive to changes in the weight and the p-parameter of the technique while the cooperative game theoretic approach is relatively robust with respect to changes in the worst utility set.     

公司资本制度改革刍议

公司资本制度是现代公司企业制度的核心内容。在法定资本制、授权资本制和折衷资本制等三种既有公司资本制度中,我国选择了法定资本制度。这种制度的实施也给社会经济生活带来一系列问题。本文认为必须在立法层面对此进行修改,并在日常管理中加强监督检查。     

Compensatory consumption and consumer compromises: a state-of-the-art review

ABSTRACT

Compensatory consumption has been an increasingly researched yet widely debated area of consumer behaviour over the last 20 years. Extant research formulates the term as overwhelmingly negative, largely due to the simplistic and fragmented conceptualisations assumed in prior work. The purpose of the current paper is to present a comprehensive review of the umbrella term of compensatory consumption, incorporating a continuum of behaviours and accounting for the pre- and post-consumption periods including both positive and negative viewpoints. In addition, expanding upon the theory of need satisfaction, the current paper introduces a novel conceptual distinction between compensation and compromise. Finally, a proposed theoretical framework is presented that differentiates between compensatory and compromisory consumption based on the extent of consumer consciousness, rationality and rationalisation. Future research directions are offered.     

国际货运代理选择的模糊多属性决策折中比值法

经济全球化的趋势和我国对外贸易的发展,使国际货运代理越来越重要,选择合适的国际货运代理对企业从事国际贸易至关重要。文中将国际货运代理选择问题归结为一类典型的模糊多属性决策问题,进而提出相应的模糊多属性决策折中比值求解方法,既权衡了最优方案与正、负理想解之间的距离,又利用折中系数反映决策者的主观态度,使决策更具柔性,更贴近实际。文中还对一个具体国际货运代理选择问题进行了计算与分析研究。     

基于模糊多属性群决策的维护方式选择研究

维护方式选择是维护管理中的重要工作之一,合理的维护方式既能达到保障设备的稳定运行,又能同时兼顾其它各个方面的要求.由于对维护方式的评价涉及多个部门、人员和属性,有些指标只是一个模糊的概念,因而采用模糊多属性群决策的方法对维护方式进行优先抉择.本文结合A公司的设备维护方式选择问题,尝试使用模糊多属性群决策折衷算法求解最佳...     

我国政党影响立法的作用机制的实证分析

西方不同政体形式下政党对立法的作用机制有不同于我国的运行状态．这些机制对于我国现阶段有借鉴价值。我国政党影响立法的作用机制有高效、稳定等特点．但也存在着不少的弊端．我们需要将西方国家政党体制中的政党间妥协机制、利益吸纳机制、党派活动的规则以及政党间的制衡策略等先进的经验和理念融入到我国的政治改革中．并用制度和法律将之规定下来付诸实施。     

履行和解浅议

一般情况下履行和解不具有独立性与可诉性，因其表现形式不同，性质认定上及效力上有差别：对于没有约定诉讼权利义务的履行和解，只有实际履行才能产生对抗执行与消灭实际权利义务的法律效力；对于约定诉讼权利义务的履行和解，其从本质上属诉讼契约。对于此类履行和解，若一方违反程序性约定，启动或放弃某项诉讼程序，应首先审查双方关于实体部分之合意是否切实履行，若已履行，应认定该行为不合法而否决其效力：若并未合理履行，则该违反程序约定之行为并非无效。     

Consumer Perceptions of Sustainability: A Free Elicitation Study

While sustainability has long been conceptualized as comprising three pillars (ecological, economic, and social), extant research and practice tends to focus on the ecological dimension of sustainability. Sustainable products and services are often marketed as a proxy for “environmentally appropriate” without considering other dimensions. As a result consumers may be under the misconception that sustainability is a one-dimensional concept and the way that researchers and marketers are employing this term may be perpetuating this (mis)understanding. This research explores the way that consumers interpret this construct. The results lend support to the argument that a one-dimensional operationalization of sustainability may be underestimating the importance of the social, economic, and time dimensions in consumer perceptions.     

Compromise effect and consideration set size in consumer decision-making

The compromise effect dictates that a decision-maker chooses a middle option over an extreme one given a set of choice alternatives since choosing an intermediate option is easier to justify, less likely to be criticized, and is consistent with loss aversion. Our experiment is designed to identify whether the connection between the extremeness of the options and the size of the consideration sets is economically and statistically significant and thus would have important behavioural implications. Specifically, we compare decision-making under small and large consideration sets where the extremeness of the comprising choice options is high, as opposed to low. The results demonstrate that an increase in consideration set size leads to weaker compromise effect (i.e. boundary condition) but when composed of high extremeness, strengthens the compromise effect.
