In the process of developing " the dss of army waterway transportation " an 0 - 1 integer linearity programming model of ' ' choosing ships " problem is established . the model has more than 100 variables so the traditional approaches are incapable 0 - 1规划是一种重要的整数线性规划模型，本文在实际开发“部队水路输送决策支持系统”的过程中，对选择可用船问题建立了0 - 1规划模型。
2.
This paper also suggests an effective method of preventing premature of genetic algorithm is presented based on the analysis of causes of premature of genetic algorithms . some different local optima are found firstly and the best of these solutions is regarded as the last result . 0 - 1 integer linearity programming is an important integer programming model 另外ga在应用中还存在早熟收敛的问题，本文介绍了解决该问题的一种策略，对一个优化问题连续多次运行ga以求得多个不同的局部最优解，再从这多个局部最优解中挑选一个最优的作为算法的最后结果，该方法可大大提高了ga求得真正全局最优解的可能性。
