企业物流网络的效率很大程度上取决于物流网络结构的合理性,只有结构合理才能使物流系统获得整体上的优化。而判断物流网络结构是否合理就要对其进行绩效评价。本文提出采用AHP与模糊综合评判法相结合的方法,通过AHP确定各指标权重,用模糊综合评判法对物流网络结构进行评价。结合某企业实例,验证了方法的可行性、实用性和有效性。  相似文献

首先建立了评价国家竞技体育实力的8大指标.在指标权重的确定方法上,分别运用夹角余弦法、系统聚类法和变异系数法给AHP群决策中每位专家赋予不同的权重,然后,结合专家权重对各专家判断矩阵的权重向量进行加权平均,得出各指标的综合权重.最后,以北京奥运会成绩为例,从定量角度对世界主要体育大国的竞技体育总体实力做出科学评价.  相似文献

从人的行为、物质、环境三维视角,分析了导致安全事故的主要原因,构建了煤矿企业安全危机预警评价指标体系.基于评价指标具有不确定性、随机性和模糊性等特点,采用模糊层次分析法(Fuzzy AHP)建立了煤矿企业安全危机模糊综合评价模型.模型中采用层次分析法确定各参数指标的权重,采用专家打分法确定安全危机因素评判模糊集,采用模糊综合评价法,探讨了多层次下危机等级的确定方法,由此可对煤矿企业进行安全危机评估与预警.以湖南省某煤矿企业为例进行了实证分析,结果表明该煤矿企业安全的总体状况较好.该理论与方法可为煤矿企业安全防范与预警提供一种有效途径.  相似文献

鉴于生态补水评价中各指标的不确定性和模糊性,将AHP理论求得的权重引入到灰度分析中,应用于生态补水综合评价,建立了基于AHp的灰色关联度模型。引用AHP所反映数据本身的效用值来计算指标的权重系数,有效地避免了权重分配困难的问题。该模型以一种新的方法进行生态补水综合评价,并结合实例进行应用,通过与综合评判法及属性识别法的比较,进一步验证了该模型的合理、简便和实用。  相似文献

软件项目的模糊风险评估及风险控制   总被引:3,自引:0,他引:3  
介绍了软件项目中风险评估及风险控制的概念和一般过程。对软件项目提出了一种综合风险评估方法。采用AHP方法与模糊逻辑法相结合的方法进行风险评估,并根据软件项目管理的实际情况对AHP方法与模糊逻辑法进行了改造。应用模糊逻辑法对各因素的评判不是直接评价其重要度,而是将各风险因素从概率方面、从影响方面、从不可控制性方面分别进行评判。先用AHP方法将风险评估分为三层,在确定第三层各风险因素的排序权向量时采用模糊逻辑法。最后利用AHP方法求出各风险因素的综合风险权重。在确定了项目的风险,并作出了评估和排序后,对这些风险采取适当的方法进行有效的风险控制。  相似文献

对于SDN企业在合作伙伴中的选择问题,文章首先由相关专家根据各指标因素的相对重要程度对其赋予相应的权重,然后利用层次分析法由各级判断矩阵求得各层次指标的权重,最后通过赋予恰当的主观权系数将这两种权重进行加权平均从而得到各指标的最终权重;再运用模糊综合评判法确定各个方案的评价指标,然后进行综合排序并得到评判结果;最后结合具体实例验证了该方法的实用性。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献
