英文摘要：

Stochastic chance-constrained programming widely exits in different fields as a certain kind of important stochastic programming. In order to find an algorithm which can more effectively solve this programming problem, random simulation is adopted to approximate the stochastic function, and random simulation is used to realise estimating the fitness value in particle swarm optimization and for the purpose of checking the feasibility of the solution, thereby a new algorithm for stochastic chance-constrained programming is presented accordingly. Finally, the performance of the proposed algorithm is tested and compared with genetic algorithm, experimental results illustrate the correctness and the validity of it.
