The practical application of decision support systems in marketing is still in its infancy, even though academic research
has been recommending the use of such systems for years. This is largely due to the lack of a single, generally applicable
decision support system. The specific requirements and problems of management are too dissimilar to make the development of
one universal decision support system feasible. However, improved PC performance, enhanced market survey methods such as conjoint
measurement, and further developed programming tools permit the varying requirements to be fairly flexibly met. The following
article describes state-of-the-art know-how regarding the practical utilization of such systems, and addresses the preconditions
for employing them. We have included many examples gathered from our own experience with numerous applications. 相似文献

This paper proposes to give a toll to help decision makers in critical situations. The principle of our research is based on a modelling approach for Cooperative Knowledge Based Systems. This approach is based on a Task/Method paradigm that we describe. We then propose to take into account collateral effects of tasks in order to support decision makers in a critical context. The proposed tool can then generate a degraded solution for which, collateral effects of previous tasks have been taken as new goals to reach. This study is possible thanks to the definition of several kinds of models: a Good Functioning Model and a Degraded Tasks Library. 相似文献

The purpose of the 1992 French Water Act is to encourage negotiation and dialogue among local stakeholders within a framework which is very similar to a patrimonial approach. Potential use of models in such post-normal approaches is analyzed. Two kinds of models are compared: one is agent-based, the other follows a more classical approach. They are compared according to their contributions as negotiation support tools. This comparison is based on a specific collective decision process dealing with water allocation at the sub-basin scale, in which authors are involved. Both are used to support collective decision processes through simulation of resource use dynamics. Agent-Based Models entail the broadening of spatial information of actors in the process, revealing inter-connected topics not taken into consideration earlier. This makes it possible to remain relevant, despite the sometimes rapidly evolving stakes. The central point of this paper is the implementation, within a practical application, of theories advocating the use of ABM as a collective decision support system. This application promotes a better understanding of the kind of support ABM provides and the way it does so. This is brought about more by re-framing the discussion and modifying the representation of the system on the part of the stakeholders than by providing specific agreements. 相似文献

日本油料发展政策及对我国的启示 总被引:1,自引:0,他引:1
日本是油料进口大国,近年来日本采取一系列的保护政策刺激国内油料生产,一方面以国内支持方式鼓励本国农民种植大豆等油料作物,另一方面利用边境措施来保护国内油脂加工业的发展.这些政策措施大大减少了植物油的进口量,保护了日本农民利益和促进了油脂加工业的发展.目前中国也是植物油的进口大国,进口量占到总需求量的一半左右.因而,学习借鉴日本油料发展政策,对于发展我国油料产业,保证食用油脂安全有着重要的现实意义. 相似文献
