Abstract: Firstly,based on existing works,the interactions between organizational design and environment are analyzed.Secondly,a model of task environment is proposed which can model the environmental uncertainty from complexity and dynamic state of task information.In the model,the complexity of environment is modeled according to Aldich's theory and NK model.Furthermore,the multi-agent modeling and simulation is used to model the task environmental turbulence.Then through a set of simulation experiments, how the design variables are matched so as to adapt the environment is researched and an analysis framework of interactions between organizational design and environment is outlined.At last,the implications of the results for the practice are put forward in the conclusion.

Key words: organizational design, environmental uncertainty, NK model, multi-agent modeling and simulation
