In appraisal items choosing , we divide the items into three categories : profits , risk adjustment , and fluidness . detailed appraisal items are also set up to mirror the funds achievement comprehensively . in appraisal method choosing , we adopt universality analysis and the common used data envelopment analysis ( dea ) together , i . e . , analyze the score of the numbered items first , then use dea and the analyzing software ems to calculate the funds " relative validity and get a rank of fund comprehensive achievement , trying to reflect the funds items and performance objectively 在基金的评价指标选择方面：将基金的评价指标主要分为三大类：收益类、风险调整类和流动性类，并设定了细分评价指标，力求全面地反映基金的业绩水平；在评价方法选择方面：采用了一般性分析和基金评价中目前较为流行的数据包络分析( dea )相结合的方法，即通过对指标的量化评分进行比较分析，通过数据包络分析法，利用ems分析软件计算基金的相对有效性，从而进行综合业绩排名，力求客观地评价基金的各项指标和综合绩效。
Because of the difference in environment , energy and process data , this paper uses analytic hierarchy process to build process planning evaluation model to add the relative efficiency of data . according to the result of relative index , an optimal green process planning approach is produced . the directed graph of process planning is built based on graph theory and the improved dijkstra algorithms is put forward to search the optimized process route 由于环境、能源及工艺数据标准的不一致，为了增加数据之间的相对有效性，本文引入层次分析法，建立了工艺决策层次评价模型，通过对相关指标的计算，得出了相对绿色的工艺决策方案：引用图形理论的基本原理，建立加工方案有向图网络，并提出改进的迪克斯特拉算法求解最优加工路线；最后给出绿色capp系统的原型框架和具体实现。
Based on the study of regional industrial structure optimum theories and optimize methods , this paper studies the definition of inferior posiyion industry , the meaning and the reason , then puts forward a new estimate system of inferior position industries : uses the method of data envelopment analysis ( dea ) to analyze the relative validity among industries , then according as synthesis benchmark modulus of industries , consulting the degree of pollution and energy efficiency , combining qualitative analysis , estimate all industries " efficiency and development potential , finds out the inforior industries in certain region 论文在深入总结了区域产业结构的内涵及演化趋势的基础上，分析了劣势产业的定义、成因及其特点，探讨了产业结构优化理论和优化方法及其模型，建立了一套劣势产业的评价指标，并提出了一种新的劣势产业评价方法模型，即先用数据包络分析法( dea )评价产业的相对有效性，然后根据该产业的综合基准系数，参考其环保、节能指数并结合具体产业进行定性分析，从而确定出一个区域的劣势产业。
In this thesis , in order to resolve the difficulties encountered by the existing dea models used to evaluate the dmus " relative efficiencies , idea efficiency set model and its parameter model are brought forward for interval number . and these models " proprieties are analyzed at the same time . then a new order - sorting method is put forward when idea efficient dmus " characters are deeply studied 本文针对现有dea模型在评价输入输出指标中含不确定因素的决策单元时存在的局限，提出了区间dea效率集及其参数模型，并研究了该区间dea模型的各项功能，同时深入分析了区间dea有效决策单元的性质，提出了能体现区间dea有效决策单元之间相对有效性优劣的排序方法，从而建立了区间dea的理论和方法基础，完善了现有dea理论方法体系。
