With the gradual development of technology and war concept, Integrated Joint Operation (IJO) has become an important combat mode. The change of operation mode will inevitably lead to change in the development of equipment support and logistics support system (LSS). And the LSS of IJO shows the characteristics that differ from general equipment LSS, such as integration of support resources, networking of command system. Traditional logistics support system developing method appears to be inadequate in dealing with such a complicated system, which gives system description by texts and diagrams. This paper analyzes the functions, organizations and recourses of the IJO logistics support system deeply. Then an architecture develop method is presented with the combination of features of DODAF architecture. The description method of support system is given by DODAF product based on the view products appropriate selection according to the system characteristic. The develop progress and order of system architecture, activities, organization, resource, information and business flows among departments as well as the mapping relationship among the constituent elements is also presented. The results show that the architecture develop method based on DODAF can provide multi-perspective description of the support system, providing auxiliary basis for operational decision making and engineering personnel to improve system performance. The method can contribute effective technical support to the design and establishment of the LSS of IJO.
