Under the environment of rapid scalable batch production demand，the paRem of extended manufacturing‘‘super-network”chain of large engineering equipment is put forward based on the concept of extended collaborative manufacturing resource．“RKCQ’’flow model of extended manufacturing capability cell is given．The reference model system of extended manufacturing‘‘supernetwork'’ chain is also constructed,as well as the constructing process model and the enable technology framework, whose purpose is to provide manufacturing capability reserve for large engineering equipment manufacturing  system dealing with the uncertain demand．
