According to the supply chain of a complex product, a multilevel model is developed for a main manufacture to
control the outsourcing quality from its suppliers. A new platform is proposed to collect quality data existing in the supply
chain, which can be presented into a multi-objective program. Additionally, a network, which is composed of different
platforms by connecting with resources, is designed to help the suppliers to manage their outsourcing quality. Finally, an
aircraft supply chain is selected to show the feasibility and effectiveness of the proposed method.
