Evaluation of the performance of GDSSs has been dominated by an experimental and laboratory based approach. Other writers
have argued for evaluation to be based in the “real-world” of decision making teams. The evaluation criteria have tended to
ignore many of the issues that would be paramount for some of the stakeholders in the evaluation process. This article seeks
to explore the criteria that might be used by a wide variety of stakeholders, including developers, facilitators, clients,
key actors, vendors, as well as academics. By drawing together the criteria associated with all of the stakeholders we discover
a broader, and possibly more thorough, framework for evaluation. The evaluation of any particular GDSS in relation to other
GDSSs can then be seen in the context of contingent weighting applied to each of the criteria where each GDSS is able to be
seen in its best light and in relation to its declared aims.
This article argues for a more eclectic and contingent approach to the evaluation of GDSSs which will encourage their future
development to be clearer about purpose and the boundaries of their use. 相似文献

改革开放以来,我国迅速成为制造业大国,但还远远不是制造业的世界中心。只有认清我国制造业存在的预期利润低、结构不合理、产业链的低端定位、边际效应递减、研究与开发费用不足以及教育结构对制造业的瓶颈效应等问题,并对症下药,才能将我国的制造业真正做大做强。 相似文献

We develop a model explaining the consolidation patterns in the agricultural biotechnology industry. Among different consolidation and cooperation mechanisms, we consider collaborative and licensing agreements, joint ventures, acquisitions, and exchanges of ownership and spin-offs. The key results derive from the benefits of coordinated actions, distinction between transferable and nontransferable payoffs, the substitutability, complementarity, and the importance of the managers' noncontractible investments, and access and expansion of markets. Results from the model are used to examine the cooperation and consolidation activities for four major players in the agricultural biotechnology industry, DuPont , Dow Chemical , Monsanto , and Novartis . 相似文献

This paper offers an empirical analysis of the relationship between income sharing rules and physician heterogeneity in medical group practices.The economies to group formation associated with risk–sharing, mutual monitoring,and internal referral are served by sharing at least a portion of group income equally. Sharing group income equally is problematic, however, when group members differ in their contribution to group income. Member contributions to group income may differ because of differences in ability, effort, or the price of services across specialty fields. The analysis below is addressed to the question of how income sharing rules in physician groups are affected by variation in member contributions. The analysis finds evidence that heterogeneity in member contributions to group income limits the use of equal income sharing rules in multispecialty groups relative to single specialty groups, and large groups relative to small groups. Nevertheless, 65% of all groups in the survey share at least a pn of group income equally, which broadly suggests that the joint surplus enhancement from risk sharing, mutual monitoring, and internal referral are sufficient to overcome the incentive problems of such rules 相似文献

Operational Research and the environment 总被引:1,自引:1,他引:0
The discipline of Operational Research (OR) is primarily concerned with improving the effectiveness and efficiency of decision processes. These processes take place everywhere in society: industry, banking, agriculture, government, politics. Frequent use of mathematical optimization models is typical of OR. Since the early '80s these models are increasingly packaged in a user-friendly way, as Decision Support Systems. In the following we will illustrate how OR can be used to describe and solve a number of environmental problems. 相似文献
