Abstract: Two-stage stochastic integer programming problems arise in many practical sit-uations, such as production and manpower planning, portfolio selections and so on. In general, the deterministic equivalences of these problems can be very large, and may not be solvable directly by general-purpose optimization approaches. Sample average approximation is an approach for solving chance constrained programming is adopted. After using scenario analysis technique, a direct search approach based on reduced gradient method is used for solving the deterministic model which would be a nonlinear integer program.
