摘要: 为提高供应链的稳定性,基于信息论、系统理论以及控制工程理论研究了供应链中的不确定性信息失真问题.首先,给出信息失真的广泛定义并从信息传递和处理的角度分析供应链中存在的不确定性信息失真问题;其次,对一个简单的二级供应链订货子系统建模,研究2种情况——无信息共享的供应链和共享最终顾客需求信息的供应链的系统传递函数和频率响应特性,并分析不同程度的信息失真情况在供应链绩效方面产生的影响;最后,采用信息论和控制工程理论的方法,有效度量了信息共享机制为供应链成员带来的收益.

Abstract: Based on information theory,systems engineering and control engineering theory,the uncertain information distortion problem in a simple two-stage supply chain was studied for the purpose of improving the stability of supply chain system. Firstly, the uncertain information distortion was generally defined and analyzed from the viewpoint of information transferring and processing. Secondly, the ordering subsystem model of a simple two-stage supply chain was built. The system transfer function and frequency response characteristics were analyzed. Two scenarios were considered: one is the traditional supply chain in which the members do not share information, the other one is the integrated supply chain in which the end customer demand information is shared by all members. According to these analyses, the influences of information distortion on supply chain performances were discussed. Finally, the benefits of information sharing in supply chains were effectively measured by using information theory and control engineering approach.
