基于熵理论的建设项目参与者多目标协同群决策模型 总被引:1,自引:0,他引:1
建设项目参与者之间的协同决策是项目参与者协同管理的本质要求。目前,在建设过程中还存在工作效率低、超预算、超工期、安全事故时有发生等弊病,这些弊病的产生和建设项目参与者之间的缺乏合作、信任和有效的信息有密切关系。建设项目参与者协同管理的目的之一就是要协调业主、总承包商、分包商、供应商等建设项目参与者之间的决策,做到参与者的群(协同)决策,降低或消除上述弊病,提高项目建设绩效,协同决策还是避免建设项目参与者群决策的双边际效应、减少不确定性、提高决策理性的有效途径,是建设项目参与者协同管理的重要体现。本文使用熵理论中的熵权及相对熵,构建了建设项目参与者协同决策的多目标群决策模型。 相似文献

Drawing on both organizational behaviour and employee relations perspectives,the paper defines participation as `opportunity to influence decisions,' andconsiders the impact of the micro-political behaviour of organization membersin pursuit of their interests on the development of genuine participation.Three types of micro-political strategy are identified and their implicationsdiscussed: information control, flexibility, and stage-craft. The discussionis illustrated with findings from an international study of decision making,and brief comment is made on international cultural differences as acomplicating factor. It is suggested that the role of participation in enhancing the knowledge baseof the organization has been neglected. If genuine participation is to beinstituted, decision making will become more complex, requiring negotiation,not only of competing interests but also of what is to be accepted as`knowledge' in the organization. This in turn will place greater demands onthe intellectual skills and personal behaviour of participants. 相似文献

Through a series of game‐theoretical models, this study systematically examines decision making in cross‐functional teams. It provides a framework for the design of an organization‐specific decision‐making process and for the alignment of a team's microdecision with the “optimal” decision that maximizes the firm's payoff. This study finds that even without changing the team leader, firms could change and even dictate the team's microdecision outcome via adjusting the team member's seniority, empowering team members with veto power or involving a supervisor as a threat to overrule the team decision. This finding implies that to reposition products in the marketplace, structuring cross‐functional teams’ microdecision‐making processes is essential. 相似文献

Organizational Theory and the Stages of Risk Communication 总被引:1,自引:0,他引:1
Caron Chess 《Risk analysis》2001,21(1):179-188
The evolution of risk communication has been described as a series of communication strategies. This article suggests that organizational theory provides another dimension to understanding the evolution of risk communication, and that risk communication can be seen as an organizational adaptation of chemical manufacturers to external pressure. Following the tragedy in Bhopal the chemical manufacturing sector's loss of legitimacy led to destabilization of its authority and to increased uncertainty in its external environment. Risk communication was one means to increase legitimacy, thereby decreasing uncertainty and potential impact on resources. However, although risk communication may evolve from crises of legitimacy, the concept of "isomorphism"--conformance to norms within a corporate sector--predicts this need not be the case. 相似文献

Abstract In times of vivid debates about the role of women on corporate boards, this article investigates the contribution of women directors to board decision‐making and strategic involvement. Based on survey data from multiple respondents in 120 Norwegian firms, we find that women directors influence board strategic involvement through their contribution to board decision‐making, which in turn depends on women directors' professional experiences and the different values they bring along. Drawing upon stereotype threat theory, we further find that perception of women as unequal board members may limit their potential contribution to board decision‐making. 相似文献

Two methodological steps in the study of peoples'concerns are elicitation and classification. Elicitation of concerns through analytical methods such as surveys can be supplemented with techniques that perform more diversively. We present two examples of how this can be accomplished: one in the expert community and one in the lay community. A classification taxonomy is a subjective choice of the researcher and it can only be evaluated against the stated objectives of the research. We present a classification schema that is explicitly oriented toward diagnosing the substantive needs of public discourses about risk decision making. To illustrate how concerns can be elicited in a social setting and how this classification tool can be applied, we report on a public participation exercise in New Jersey where citizens discussed the impacts of land application of sewage sludge at an experimental farm. 相似文献

Green infrastructure is a strategic planning concept that is able to address environmental, social and even economic problems by supplying a variety of benefits for society. Especially in times of public financial crises and spatial transformation, it is important to ensure that those services are high quality to guarantee that they will provide the intended benefits by integrating stakeholders’ knowledge and experience into green infrastructure planning. Active stakeholder participation leads to legitimate and informed future planning that accounts for society’s needs. This paper investigates participation approaches of six green infrastructure investments in Belgium, the UK, Germany and the Netherlands. The major aim is to explore how and when participation should take place to optimize participation in green infrastructure planning. This is achieved by surveying the stakeholders involved and conducting stakeholder discussions to identify their views on the participation approaches employed and their integration into the planning process. We found that stakeholders were generally satisfied with how they were involved but desired a broader and more tailored mix of approaches. Furthermore, we found several Arnstein gaps, which lead us to conclude by suggesting recommendations that are helpful for successful participation in green infrastructure planning. 相似文献

针对目前语言型多属性决策方法大多基于期望效用理论且不考虑指标间影响关系的不足,提出了一种将后悔理论和决策试验与评价试验法相结合的语言型多属性决策方法。首先,依据后悔理论的思想,定义了语言后悔-欣喜函数,给出了方案感知效用值的计算公式;然后,利用决策试验与评价试验法分析指标间的影响关系,给出了基于语言DEMATEL的指标权重确定方法,再通过指标总容量最大优化模型给出了基于注水原理的指标权重确定方法,并在此基础上求解方案的综合感知效用值,据此对方案进行排序择优;最后,通过两个应用实例来验证所提方法的可行性和有效性。实例结果表明,由于该方法同时考虑了决策者的心理行为和指标间的影响关系,因此可使决策结果更加贴近现实且更为可靠。 相似文献

Nuclear waste cleanup is a challenging and complex problem that requires both scientific analysis and dialogue among a variety of stakeholders. This article describes an effort to develop an online information system that supports this analytic-deliberative dialogue by integrating cleanup information for the Hanford Site, and making it more \"transparent.\" A framework for understanding and evaluating transparency guided system development. Working directly with stakeholders, we identified information needs and developed new ways to organize and present the information so that it would be more transparent to interested parties, with the ultimate aim of fostering greater participation in decision dialogues and processes. The complexity of the information needed for dialogue suggested that several types of communication devices (\"information structures\") were warranted. Five information structures were developed for the pilot Decision Mapping System (http://nalu.geog.washington.edu/dms). Decision maps hyperlinked decision information to maps of Hanford. Background Information provided context in a narrative format. Decision Paths organized decision process information on a timeline and provided direct hyperlinks to online documentation. The Geographic Library hyperlinked decision documents to maps. Finally, a Discussion Forum allowed users to make comments and view remarks from others. Early lessons from this work suggest that transparency is integral to long-term management, a participatory design process contributed greatly to its perceived success, and better data integration to support decision making is needed. This work has broad implications for risk communicators and risk managers because it speaks to the design of information systems to support \"analytic-deliberative\" decision processes (i.e., those that rely upon both risk science and public dialogue). 相似文献

Summary The role of decision tools in managerial decisions can be crucial. Yet, there is very little research seeking to understand
and measure the influence of planning models on decision-makers’ actual behavior or performance.
We focus on investigating, in an experimental context, the influence of a decision model (time allocation model) on student
subjects’ changes of mind and behavior. Of special interest is the effect of the articulated importance of criteria on subjects’
choices. Furthermore, we have also studied how the above mentioned model influences subjects’ actual (measurable) performance.
The results are partly conflicting, though interesting: (1) the (biased) decision model did have a significant influence on
the subjects’ choices, (2) when the model provided additional freedom to improve criterion values, the subjects’ choices were
rather inconsistent with the articulated importance of criteria, (3) the interpretation is not clear, how plans influence
actual behavior, and (4) the subjects did not fully recognize the bias of the model (when present). However, our findings
very clearly demonstrate that model developers have a great responsibility. Biased models may guide managers to make dramatically
erroneous decisions in bona fide. We hope that our findings generate additional research into this important, but under-researched
topic.

To inform local and regional decisions about protecting short-term and long-term quality of life, the Consortium for Atlantic Regional Assessment (CARA) provides data and tools (for the northeastern United States) that can help decision makers understand how outcomes of their decisions could be affected by potential changes in both climate and land use. On an interactive, user-friendly website, CARA has amassed data on climate (historical records and future projections for seven global climate models), land cover, and socioeconomic and environmental variables, along with tools to help decision makers tailor the data for their own decision types and locations. CARA Advisory Council stakeholders help identify what information and tools stakeholders would find most useful and how to present these; they also provide in-depth feedback for subregion case studies. General lessons include: (1) decision makers want detailed local projections for periods short enough to account for extreme events, in contrast to the broader spatial and temporal observations and projections that are available or consistent at a regional level; (2) stakeholders will not use such a website unless it is visually appealing and easy to find the information they want; (3) some stakeholders need background while others want to go immediately to data, and some want maps while others want text or tables. This article also compares what has been learned across case studies of Cape May County, New Jersey, Cape Cod, Massachusetts, and Hampton Roads, Virginia, relating specifically to sea-level rise. Lessons include: (1) groups can be affected differently by physical dangers compared with economic dangers; (2) decisions will differ according to decision makers' preferences about waiting and risk tolerance; (3) future scenarios and maps can help assess the impacts of dangers to emergency evacuation routes, homes, and infrastructure, and the natural environment; (4) residents' and decision makers' perceptions are affected by information about potential local impacts from global climate change. 相似文献

This paper develops a distributed decision‐making framework for the players in a supply chain or a private e‐marketplace to collaboratively arrive at a global Pareto‐optimal solution. In this model, no player has complete knowledge about all the costs and constraints of the other players. The decision‐making framework employs an iterative procedure, based on the Integer L‐shaped method, in which a master problem is solved to propose global solutions, and each player uses his local problems to construct feasibility and optimality cuts on the master problem. The master problem is modeled as a mixed‐integer program, and the players' local problems are formulated as linear programs. Collaborative planning scenarios in private e‐marketplaces and in supply chains were formulated and solved for test data. The results show that this distributed model is able to achieve near‐optimal solutions considerably faster than the traditional centralized approach. 相似文献

本文研究了具有领导的二分群体决策中领导对决策收益的影响,得到的一个重要结论是:如果二分群体决策过程应用了独立投票过程下的最优规则,则领导对其他决策者施加影响不可能提高群体决策收益。然而当群体未能应用最优决策规则时,领导的影响有可能发挥积极作用,这主要是由于此时领导的决策能力高于其他决策成员,而决策规则分配给领导的权重相对过低而导致的。 相似文献

This paper develops a new integrated evaluation and planning approach for implementing a given set of best practices in a prioritized and phased manner. The best practices are implemented for achieving lower-level business unit objectives and higher-level strategic goals of an organization. With a multiattribute decision making algorithm under the balanced scorecard (BSC) framework, a new evaluation model is developed to effectively measure the relationship between lower-level objectives and higher-level goals, and to give each best practice a relative priority value. A new adjustment method is also developed to address potential biases in the self-assessment process at the business unit level. The evaluation model enables the prioritization and implementation planning of best practices in terms of their importance and achievability from the viewpoints of the organization, four BSC strategic perspectives, individual business units, and the overall implementation planning zone. An empirical study is conducted to demonstrate the applicability and effectiveness of the integrated evaluation and planning approach. 相似文献
