摘要
借鉴了生态学中生物生态位的概念和理论,分析了虚拟企业生态位概念的内涵。从虚拟企业生存、进化和竞争的三维生存空间角度,建立了基于“态”、“势”、“位”概念的虚拟企业生态位评价体系。构建了基于BP神经网络的虚拟企业生态位评价模型,利用MATLAB神经网络软件包进行仿真计算,并通过典型算例验证了该方法的有效性。
This article presents the biological characteristics of virtual enterprise, and based on it, the connotations of virtual enterprise＇s niche are analysed. Through the research of virtual enterprise＇s survivorship, evolution and competition, it designs an index system of virtual enterprise＇s niche according to ＂ecostate＂, ＂ecorole＂ and ＂position＂ of niche, and presents a niche＇s model which is based on the BP neural network. The Neural Network Toolbox（NNT） based on MATLAB is used to make network compute. Finally, through a simulation example, the effectiveness of the proposed method is verified.
