Important factors, such as knowledge absorption capacity, update rate of knowledge in the network, discount rate, the time of knowledge transfer, market share, product life cycle, etc. are taken into account in the model. A large number of simulated experiments are implemented to test the efficiency of the optimization model. Simulation experimental results show that the calculated results are in accordance with the actual economic situation. The optimization model can provide useful decision support in knowledge transfer time for enterprises.]]>Bae, J. and J. Koo,2008Chang, M.H. and J.E.
