根据农业生产的实际工作,建构一个基于混合Petri网的工作流模型.混合Petri网一般由连续和离散两个部分组成,模型连续的部分主要反映农田实际工作的进程,离散部分主要表示农机和劳动力等资源状况的变化,提出的模型还可以模拟在生产过程中的工作和间歇状态.仿真结果表明,混合Petri网模型能准确地描述农业生产的过程,在出现不确定因素的情况下能重新分配资源.该模型作为农业生产规划的参考模型,促进在不确定的环境中相关优化算法的发展.
According to the actual work of agricultural production, we construct a workflow model based on hybrid Petri net.Mixed Petri nets generally consist of continuous and discrete parts, the continuous part of the model mainly reflects the actual working process of farmland, the discrete part mainly represents the agricultural machinery and labor force Etc. The proposed model can also simulate the working and intermittent status in the process of production.The simulation results show that the hybrid Petri net model can accurately describe the process of agricultural production and redistribute in the event of uncertainties As a reference model for agricultural production planning, this model promotes the development of relevant optimization algorithms in an uncertain environment.
