In view of the disadvantages of the current research on the task assignment problem of product development,
the mathematical description and constraint conditions of the problem are presented. The related matrixes of the task
assignment model are proposed. The objective function of multi-objective optimization is built based on weight factor and
range transform method. According to the dynamic characteristic and uncertainty of task assignment process, the dynamic
assignment oriented ant colony algorithm based on sequential logic is proposed. The advantages and steps of the algorithm
are analyzed. Finally, a simulation test illustrates the feasibility and effectiveness of the proposed method.
