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.
