Quality Supervision in Logistics Service Supply Chain

Analyzes the validity of quality supervision in logistics service supply chain. Focuses on a supply chain structure including a logistics service supplier and an integrator, a quality supervision model under asymmetric information is established based on a basic model of quality supervision in logistics service supply chain under symmetric information and an equilibrium result is obtained, then the influence on quality supervision is considered after two factors - one is that the logistics service integrator will be punished and the other one is a competing factor among suppliers - are introduced and new results are got. Simulation results show that the quality completion level of supplier rises up and the quality supervision level of integrator brings down after the factors are introduced. Therefore, in practice, the level of logistics service in logistics services supply chain can be improved effectively through strengthening the punishment of integrator and establishing competing mechanism of suppliers.
