It studies coordination of ocean economic complex system , and brings up the method of coordination of ocean economy : muti - objective decision making model for ocean economy and ocean sustainable development is set up with muti - objective analysis ; with the theory of unbalanced system , it analyses sustainable evolution pattern and realization path of ocean economic complex system . it establishes coordination analysis model between sub - system and internal system of ocean economic complex system with calculation method 2 、研究了海洋经济复合系统的协调性问题,提出了海洋经济协调性分析方法:运用多目标分析方法建立了海洋经济和海洋可持续发展多目标决策描述模型;运用非平衡系统理论,分析了海洋经济复合系统持续性演化模式及实现的途径。建立海洋经济复合系统子系统内部与子系统之间的协调度分析模型,并给出了协调度的计算方法。
It sets up the models of voc ' s fuzzy model establishment and voc ' s fuzzy synthesis , model for assessing users " competition , and model for assessing qc ' s importance , etc , thus lays the technical foundation for building the decision making model in hoq as well as the intelligent computer aided qfd system ( icaqfd ) 建立了voc的模糊建模和voc模糊综合模型、用户竞争评估模型,及qc重要度评估模型等,为hoq中决策模型以及智能计算机辅助qfd系统( icaqfd )的建立奠定了技术基础。
Put above hypotheses together we can propose a comprehensive solving alternative to in hence decision making effectiveness for agricultural project investment : to build fuzzy analysis hierarchy process based on entropy and fuzzy multi - attributes decision making models in the model base of agricultural project investment gdss . we can to adopt group advices and experiences , promote the opinion integration and improve the solving methods of ill - structured problems that supported by group decision support system 按照这一概念框架,作者提出提高农业项目投资群体决策效果的整体解决思路:建立基于熵权的模糊层次分析法,以及模糊多属性群体决策模型的农业项目投资群体决策支持系统模型库;通过群体决策支持系统的支持,充分考虑决策群体的决策思想及经验,促进意见集结,改进结构不良问题的解决。
Suitable stocks selecting by this model have been made optimal portfolios . the empirical study show that the optimal portfolios of stocks selecting by three - dimensions entropy decision making model have a bigger expected utility and a smaller risk than the optimal portfolios selecting by only using expected utility model 分析结果表明,利用三维熵式决策模型选出的股票进行优化组合要比单纯利用期望效用原理选出的股票进行优化组合结果更优;利用该模型选出的股票在一定条件下可以达到与整体股票组合相似的最大收益和最小风险的要求。
Furthermore , the efficient frontier derived by the optimal portfolios of stocks selecting by three - dimensions entropy decision making model can fit the efficient frontier of optimal portfolios derived from the whole stocks . the three - dimensions entropy decision making criteria can help investors select a proper number of suitable stocks to make portfolio . secondly , we produce entropy weighting double points method by combining entropy weighting method and double points method 其次,将熵权法与双基点法相结合产生熵权双基点法,给出了该方法详细的思路和运算步骤,并将其应用在股票投资价值评价中,通过对六只钢铁产业类股票的实证分析表明,熵权双基点法在比较股票间相对投资价值时具有较大优势,基本上能够如实的评价待评股票的投资价值,为投资者进行投资决策提供良好可靠的建议。
