Abstract: Problem in competitive multi-sourcing network design of supply chain with resilient management based on a positive supply is studied. A supply chain integrative framework is established, integrating resilient manufacturing pricing/resilient empty inventory punishment/ resilient pre-warning/resilient members selection/resilient congestion delay/resilient transportation. Then a competitive multi-sourcing network with resilient management is established based on a general operational model of supply chain. According to the potential risk of the various distributors′ failure, a multiple-source supply with resilient management is used. Finally, a simulation is proposed with multi-level expectations tolerance and global supply chains, so as to inspect their influence to the target function, resilient performance of positive framework and manufacturers′ competition.
