基于三维动画仿真软件Flexsim,文中对航空附件加工车间这种多品种、小批量生产的作业车间(Job-Shop)进行了调度优化研究。介绍了Flexsim连接数据库的技术与遗传算法求解生产调度的方法;在Flexsim中建立虚拟生产车间模型,并且在Flexsim虚拟车间模型内部嵌入C++数据库操纵程序,将仿真模型与生产管理数据库连接,使模型可以实时采集生产数据;最后通过实例说明Flexsim仿真与调度优化相结合的方法可以有效地提高航空附件加工车间的效益,证明了方法的有效性。
On the basis of Flexsim simulation, this paper studies aircraft accessory job- shop scheduling optimization problems, which is multi - categories and small batch. First of all, the Flexsim database link method and genetic algorithm in job- shop scheduling are intro- duced. And then, the virtual workshop model is built in Flexsim environment, and embedded by database operation C + + program which could access production management database. The virtual workshop could update data from manufacturing database in real time. In the end, the simulation example confirms the method of Flexsim simulation in conjunction with scheduling optimization can improve the workshop's benefit, and is effective.
