Conventional data envelopment analysis (DEA) evaluates efficiency of system from the static and the ``black box" perspectives. It can not effectively reflect the operational performances of decision making units (DMUs) so that some deviations are produced. By taking the internal structure of system and dynamic relationship in different periods into consideration, this paper constructs a slacks-based measures (SBM) model of dynamic network system based on the cooperative game. Then, it discusses efficiency evaluation of system, which considers undesirable factors. Moreover, the model of efficiency decomposition is constructed based on the theory of multi-objective programming to analysis effects of different periods and different processes, and make the decomposition method uniqueness. Finally, the empirical case is introduced to verify feasibility and practicability of the models.
