Analysis and solution of problem of supply chain bottleneck

The problem of Supply Chain (SC) bottleneck badly influences the whole value of the SC system. Bottleneck dilatation method and dypass method can only control SC bottleneck when it has come into being. Therefore these two methods cannot solve the problem radically. As an ideal method transformed from the traditional structure of SC, Supply and Demand Network with multi-functional and opening characteristics for enterprise (SDN) is discussed, which can reduce the rate of SC bottleneck question emergence from its origin.
