Abstract:  Based on design structure matrix， the process coupling analyses were difficult to effectively solve the multi-agent decision optimization problems in the change of complex product designs， such as the coupling of process correlation， the readjust of designs， and the reallocation of design resources. Moreover， the theory of decision optimization with the agent as a completely rational agent deviated greatly from the specific practices. An optimization method of complex product design change decision was proposed considering the psychological perception of the agent under process correlation. The prospect theory was used to construct the complex product design change decision optimization model with the objective function of minimizing the psychological disturbance of the design agent repeated execution and the delay period of design change. A thing and season-based adaptive multi-objective dynamic scheduling algorithm  was proposed by using two-layer coding method combining process and design agent. At last， the rationality and validity of the above decision model and method were verified by the comparison experiments and result analyses of the example simulation.
