摘　　要： 规模化养殖环境下牧场每天都有大量人工授精任务,人工授精任务执行具有最佳时机的特性,研究借鉴"提前/拖期调度"理论建立奶牛人工授精任务调度模型,采用惩罚成本函数兼顾奶牛受孕率和产奶量,采用禁忌搜索算法和二次规划方法求解人工授精任务执行序列和开始执行时间,预测奶牛排卵时间和最佳人工授精时间。仿真实验证明了模型和算法的有效性。 There are many artificial insemination tasks in pasture everyday under large-scale cultivation, and implanting artificial insemination task has the character of optimal timing. The earliness/tardiness scheduling theory was adopted to establish task scheduling model for artificial insemination of dairy cows. Based on the tasks’ conception rate and milk yield, the cost function was proposed. Then the tabu search （TS） and the quadratic programming （QP） was used for processing the sequences of operation and the start time of operation for artificial insemination task, and for predicting the optimal time of artificial insemination. The simulation experiment demonstrated the effectiveness of model and algorithm.

关 键 词： 物联网 人工授精任务调度 提前 拖期 禁忌搜索 二次规划
