Complicated product development (CPD) is a system engineering that combines technology with management deeply. The diverse values of development engineering practice should be integrated from the height of strategic coordination are demonstrated in this paper. The management principles of CPD engineering are proposed. The theoretical framework of dynamic decision making, which consists of the strategic choice of the CPD projects, the decomposition and hierarchical optimization of the development projects, the dynamic management of the development process, skilled staff scheduling, collaborative management of suppliers, and corresponding decision support systems techniques, is constructed. Variety of optimization, scheduling and decision models and their corresponding solving methods are designed. The decision support system techniques based on information resources database, decision methods database and multi-stage feedback decision support system techniques are also proposed. The common methods used in the engineering management of CPD are summarized and the application of cloud computing to the engineering management of CPD is forecasted.
