类加权主成分分析在企业物流绩效评价中的应用 总被引:1,自引:0,他引:1
以企业物流绩效为研究对象,建立了一种较全面的二层次指标体系,综合考虑了财务、客户、市场、业务以及学习等各方面的绩效指标,并将上层指标看作是下层指标的指标类.利用层次分析法确定全体指标和每个指标类的权重系数,并对指标进行主成分分析,求得主成分;对标准化指标进行加权处理,同时考虑指标类的权重,建立了类加权主成分评价模型.通过一个示例对企业物流绩效进行评价,并将评价结果分别与主成分分析和加权主成分分析进行了比较.该模型将层次分析法的主观分析与主成分分析法的客观分析相结合,不仅考虑了全体指标的重要程度,而且考虑了物流绩效指标类的重要度差异,更加符合客观实际. 相似文献

提出了基于信息熵与超效率DEA模型(SE-DEA)的公交企业运营绩效组合评价方法,弥补了传统DEA模型无法对多个有效率单元再排序的缺陷,并降低了SE-DEA模型受指标维度影响的风险,进一步提高了其判别能力。以12家公交企业为研究对象,将公交行业监管、公交企业运营服务与乘客出行需求相结合,基于组合评价方法对公交企业运营绩效进行评价,并与SE-DEA模型得到的评价结果进行对比分析。结果表明,公交企业运营绩效值波动较大;组合评价方法所得到的公交企业运营绩效排序结果与SE-DEA模型得到的排序结果在总体趋势上是一致的,但两者测算的运营绩效值相差很大,且前者的判别能力比后者更强。根据评价结果提出可行建议,以便于顺利实施"优先发展公共交通"的战略。 相似文献

基于SERVQUAL模型的网购快递服务质量的模糊评价研究 总被引:1,自引:0,他引:1
将SERVQUAL模型运用到网购环境下的快递服务业,设计出由25个指标组成的网购快递服务质量评价体系.通过问卷调查和因子分析,将快递服务质量归结为服务前质量、服务中质量、服务后质量和企业形象4个维度来评价.在此基础上,运用FAHP获得各指标权重,建立服务质量的评价模型并进行模糊评价,最后得知网购人群对快递服务的感知和期望差距较大,并针对每一维度找出改进网购快递服务质量的策略,提升快递企业竞争力. 相似文献

DEA及其在企业物流系统评价中的应用 总被引:1,自引:0,他引:1
为了便于制造企业正确判断所建立的物流系统的相对有效性程度,为进一步完善企业物流系统提供决策依据,针对制造企业物流系统的组成特点,设计了由采购物流子系统、生产物流子系统、销售物流子系统和物流信息系统构成的企业物流系统评价指标体系。该体系以投入和产出作为变量,重点考察投入与产出的匹配性以及各个子系统之间的协调性和平衡性,以判断物流系统是否处于最佳规模状态。在此基础上,运用建立的数据包络分析法评价模型,通过一个实际算例进行了实证分析,提出了改进对策。分析结果表明:DEA方法由于具有权重是以变量的形式给出的,也无需考虑指标量纲等特点,评价结果比较客观、准确。 相似文献

This paper proposes comparisons among two different competitive power structures with and without horizontal coordination. We conduct a game theoretic analysis on the situation where two logistics service providers compete in an e-commerce logistics market with respect to the order quantity and service level decision on a particular logistics service product. Under a consumer utility-based demand, we acquire the equilibrium order quantity decisions and optimal profits under the centralised setting and decentralised setting. An analytical model is established to examine the existence of the Nash equilibrium in the service game. We then prove that the logistics service demand depends on different competitive power structures with the establishment of Cournot game and Stackelberg game model. The analytical results and the equilibrium analysis of the e-commerce logistics system are investigated. After that, we compare the equilibrium results among the centralised system, Cournot game, and Stackelberg game. To empower the horizontal carrier coordination, we design a revenue sharing contract for the decentralised model. A numerical study illustrates the impact of parameters on the optimal decision variables. In this paper, we prove the effectiveness of horizontal carrier collaboration and explicate the reason for the lower marginal profit in logistics theoretically. 相似文献

Saaty's AHP is helpful in evaluating alternatives thanks to its effective procedure to determine the relative weights of several comparison criteria. Combining the results of expert interviews, AHP can be very useful for a company in choosing a third party logistics service provider (3PL). However, in the traditional AHP procedure, several results may be rejected when the consistency ratio (CR) of the respondent exceeds a certain threshold. As a consequence, AHP interviews may be repeated several times with a consequent waste of time. In many industrial domains, a faster way to choose a supplier would thus be appreciated. In this paper we propose a mathematical method that combines AHP, DEA and linear programming in order to support the multi-criteria evaluation of third party logistics service providers. The proposed model aims to overcome the limitation of the AHP method, merging experts’ indications with objective judgments which originate from historical data analysis. Suppliers' past performance is thus used to correct eventual errors resulting from the acceptance of interviews where the consistency ratio is high. The proposed model has been validated on the real case of an international logistics service provider. 相似文献

This paper focuses on the Brazilian third-party logistics (3PL) sector which, facing increasing competition, offers clients a wide variety of services/IT technologies in the quest to bolster efficiency. The main research objective is to determine which variables significantly impact the 3PLs' scale efficiency by applying a two-stage DEA model. Based on an unbalanced panel model, secondary data from the annual study published by Revista Tecnologística (years 2001–2010) were collected and analysed. The required inputs and outputs for the analysis were identified, as were the contextual variables that can affect the scale efficiency of the 3PLs. The results support findings in the literature regarding the role coordination processes play in logistics performance. Managerial implications for both shippers and 3PLs are discussed. 相似文献

Different logistics technologies are emerging to improve the delivery efficiency and service standard of last-mile logistics. This study aims to understand consumer's usage behaviour of logistics technologies focussing on three representative logistics technologies: buy-online-and-pickup-in-store (BOPS), smart locker and drone delivery. A theoretical model is proposed by integrating the factors of habit and attitude into the unified theory of acceptance and use of technology (UTAUT). A total of 450 valid questionnaires are collected, and the data are analysed using structural equation modelling. The results suggest that (1) rational factors (i.e. performance expectancy, effort expectancy, facilitating conditions and attitude) and irrational factor (habit) collectively determine consumers' usage of logistics technologies; and (2) the key driving factors of consumers' usage behaviour of three logistics technologies do vary. The findings enrich the theoretical research on last-mile logistics and provide managerial implications for retail and logistics service providers. 相似文献
