We present a new bi-level linear integer programming model for the strategic planning of the public-private partnership. This model is an extension of the previously studied models where the ecological, infrastructure, and production projects have known schedules into the planning horizon if they start. A stochastic local search matheuristic is designed for this new problem according to the upper level variables. The optimal solution for the lower level is obtained by CPLEX software. To reduce the running time, we use randomized Flip and Swap neighborhoods. To evaluate the neighboring solutions, we solve the lower level problem approximately with a small fixed deviation from the optimum. Computational results for real world instances for the Tranbaikalian polymetal fields are discussed.
