New drug research and development( R&D) is a complex engineering of high investment,high risk and long cycle,so performing risk response in new drug R&D is necessary. This paper proposes a decision analysis method for solving the risk response strategy selection problem from the perspectives of a single risk situation and considering two risks,respectively,on the basis of analyzing the risks existing in new drug R&D. Then,an optimization model of project risk response strategy selection is constructed. Fina...
