Study on delivery reliability of push-pull mixed supply chain

After the dynamics model of push-pull mixed supply chain operations was established, delivery reliability was defined quantitatively and the simulation analysis of delivery reliability of push-pull mixed supply chain was conducted under the circumstances of disturbance of market. At the same time, the simulation of ordering cycle and target inventory's influence to delivery reliability of push-pull mixed supply chain was run. The results indicate that: for push-pull mixed supply chain, the delivery reliability can be increased only through adjusting supplier's order cycle time (not distributor's order cycle time), not through changing target inventory which only increases local delivery ratio.
