With the development of strategic alliance practice, strategic alliance pays more attention to its inter-learning and capacity improving. It focuses on how to learn from its original knowledge and routines effectively. In order to form strategic alliance successfully, we must integrate its original organizational memory effectively. Based on the characteristics of organizational memory in strategic alliance, this paper analyzes its interface and permeation, and studies the construction of organizational memory in strategic alliance organization.  相似文献

This paper investigates the multiobjective programming problems with fuzzy parameters in the constraints. First, by the decomposing theorem, we introduce a fuzzy set to characterize the constraints, then give the definition of α-quasi-efficient solution and a-efficient solution, and discuss their properties. Finally, a numerical example is presented to illustrate the differences between the refined solutions and the α-Pareto solution.  相似文献

中国股市已实现波动率的跳跃行为研究   总被引:14,自引:0,他引:14  
以二次幂变差的测量为理论基础,研究了上证综指已实现波动率中的跳跃行为.将已实现波动率分解为连续样本路径方差争离散跳跃方差,研究了跳跃方差序列的统计特征,并且应用HAR-RV-CJ模型对上证综指的已实现波动率进行预测.研究结果发现,几乎所有日、周和月已实现波动率的可预测性都来自连续样本路径方差,表明二次变差中的连续样本路径成分是中国股市已实现波动率预报的决定因素.  相似文献
