【摘要】 采用改进的加速遗传算法 (RAGA)与多维动态规划法 (DP)相结合 ,提出了遗传动态规划模型 (RA GA—DP) ,解决了多维动态规划法在求解作物非充分灌溉下的灌溉制度优化过程中的反复试算、易早熟及陷入局部最优而难于求得真正最优解的问题。本方法在三江平原井灌水稻非充分灌溉条件下的灌溉制度优化中得以应用 ,取得满意的效果更多还原

【Abstract】 By Combining the RAGA with Multi Dimensional Dynamic Planning(MDDP),the authors put forward a new method named as RAGA DP.When applying MDDP for optimizing irrigation system under the condition of non sufficient irrigation,some problems may occur,it is subject to a partial best and difficult in obtaining the optimum value and so on.The new method can be used to handle these probloms.The authors applied the RAGA—DP model to optimize a irrigation system of underground irrigation rice under non sufficient irrigation in the San jiang Plain.The result was satisfactory.更多还原
