This paper proposes an optimal transporting timber control scheme in wood logistics networks. Our approach is a time control model based on utility theory to minimize the transportation cost in wood logistics networks, three parameters are considered in the model: transportation cost, storage cost and congestion cost. A discussion of the solution to the model is given to prove the effectiveness of the model. It is shown that the optimal timber configuration can be obtained through the numerical results, the optimal timber and minimized cost can be obtained through the utility model.
