Today's commodity trading market is consumer-driven market. The growing proliferation of types of goods, commodities function continuously improved, shortening cycle of the supply of goods, continuously improve the quality standards of goods. Consumer demand for commodity multifaceted product developers only continue to strive to produce high quality products in the shortest possible time in order to seize market opportunities. In this context, the flexible production came into being. Concurrent engineering is an essential part of the flexible manufacturing. Concurrent Engineering is a product development system early in the development proactively taking into account the various parts of the whole process of the product life cycle, as early as possible to achieve the product development schedule, cost, quality control and effective risk control . Due to the high degree of parallelism, can largely shorten the construction period, improve product quality. However, it is precisely because of this high degree of parallelism, concurrent engineering is more complex, and there is a big risk. From product development, concurrent engineering point of view of the elements of the risk factors summarized into the product development process risk, IT risk, cross-sectoral collaborative risk and project management risk four categories, and the linkage between the risk factors analysis. Product development, concurrent engineering, risk control principles, including the principle of synergy, the dynamic principle and the principle of pre-control, the various departments fully collaborative risk control, tracking the dynamic development of the risk, in order to realize the pre-control risk, the risk of early containment. In the elaborate control coordination of product development, concurrent engineering, dynamic pre-control three principle, that is, into the focus of the article - the basic conditions of the product development concurrent engineering risk control methods and models. The basic conditions include four aspects, namely the optimization of the product development process, information exchange platform to build and manage cross-functional collaboration system to establish and project management system optimization. This paper presents the risk control methods including optimization of product development concurrent engineering risk control system, improve product development, concurrent engineering risk control mechanism, the application of effective risk management tools, as well as to improve the full awareness of risk prevention. Then, the article is based on GERT Graphical Evaluation and Review Technique establish mathematical model of product development, concurrent engineering risk control, the model can be described risk factors affect the progress and costs, and to estimate the degree of influence. Finally, on the basis of the establishment of product development, concurrent engineering risk control theoretical system, the article S product development, concurrent engineering, risk control, the empirical analysis. Part of the situation on the basis of the analysis, the paper proposes three areas of shortcomings, and suggest improvements.
