An evaluation of system efficiency of the enterprises' logistics system based on dea abstract: the research of the logistics is a crisscross and comprehensive analysis of multilateral subjects,which is of strong attribution of systemility、quantitality and optimality,especially in the rational analysis and evaluation of comparative efficiency of the logistics system.operations research is just a subject which focuses on the attribution of systemility、quantitality and optimality.thus ,here,or takes a very important position.its mentionable that the application of or including its models and methods is often different with those classical models BEC ause of certain especial attribution of the logistics system,as should be noteworthy here.in this paper,a new field of or ―― date envelopment analysis is recommended.dea is usually used to evaluate the comparative efficiency of units in some parallel departments or denominations.in this paper it analyzes the characteristics of the enterprises' logistics and identifies the factor scheme used for the evaluation of its efficiency.

物流研究属于多学科的交叉与综合分析，具有强烈的系统性特征、数量化特征及最优性特征。它们在物流合理化分析和系统相对有效性评价中更为突出。运筹学恰是以系统性、数量化及最优化为核心，因此，在物流合理化研究和系统相对有效性评价中占有重要地位。由于物流系统具有某些特有的属性，故运筹学在其中的运用，包括模型与方法，往往与经典的模式有所不同。本文引入运筹学的一个新领域――数据包络分析（data envelopment analysis ，简称dea）模型，一种用于评价相同类型部门中各成员间的相对有效性的模型，来评价企业物流系统的相对有效性。

Completely different crystal structures and morphology were shown in the meltdrawn films of two kinds of tacticity of sPP. A continuous conformational transform from the 〓 into the of sPP was induced by further stretching. While the zigzag conformation can retransform back to helical 〓 one after annealing above 80℃, the mechanism of conformation transform has been introduced.
