【摘要】：生产调度一直就是车间的管理核心，，一个有效的调度系统或者优化技术是实现先进制造的基础，是提高生产效益的的关键。但是一个好的完整的调度系统不只是处理静态数据，它需要在数据产生变动或者机器出现故障时候能够及时有效的拿出应对方案。而现实生产车间中很难将这个问题及时有效的解决。实时数据的车间调度问题一直都是一个复杂的巨大的难题，无论是从数据的及时获取以及数据的有效处理方面，都是需要我们不断探索的课题，为了解决企业车间后台管理信息落后，对实时数据的更新不及时等问题，本文以普通的制造业加工车间为背景，利用RFID对实时数据的采集功能，研究并设计了基于RFID实时信息的协同调度系统，并根据具体的动态调度问题提出了相关的解决方案。本文设计的RFID实时信息的协同调度系统的主要包括数据采集模块、信息的查询和处理模块和生产调度模块。为了充分的发挥调度系统的作用，有效的处理车间实时信息，本文详细介绍了如何使用RFID技术来第一时间获取车间调度信息，同事将信息传到调度系统中进行处理，实现及时在线优化。在此基础上，本文对于具体的车间动态调度问题进行描述，给出具体的车间动态调度的数学模型，提出了贪婪算法，并在此基础上给出了系统的硬件模拟以及功能实现。同时在Microsoft Visual C++6.0开发环境下，对于该系统的动态调度处理方法进行模拟仿真，体现并验证了该系统处理动态数据的及时性和有效性。
[Abstract]:Production scheduling has always been the core of job shop management. An effective scheduling system or optimization technology is the basis of realizing advanced manufacturing and the key to improve production efficiency. But a good complete scheduling system not only deals with static data, it needs to be able to deal with the problem in a timely and effective manner when the data changes or the machine fails. But the real production workshop is very difficult to solve this problem in time and effectively. The job-shop scheduling problem of real-time data has always been a complicated and huge problem, whether from the timely acquisition of data and the effective processing of data, it is a subject that we need to explore continuously. In order to solve the problem that the backstage management information of the enterprise workshop is backward and the updating of real-time data is not timely, this paper takes the common manufacturing workshop as the background and uses RFID to collect the real-time data. The collaborative scheduling system based on RFID real-time information is studied and designed, and the relevant solutions are proposed according to the specific dynamic scheduling problem. The RFID real-time information cooperative scheduling system designed in this paper mainly includes data acquisition module, information query and processing module and production scheduling module. In order to give full play to the function of scheduling system and deal with the real-time information of job shop effectively, this paper introduces in detail how to use RFID technology to obtain job shop scheduling information in the first time, and the information is transmitted to the scheduling system by colleagues for processing. Realize timely online optimization. On this basis, this paper describes the specific job-shop dynamic scheduling problem, gives the mathematical model of the specific job-shop dynamic scheduling, puts forward the greedy algorithm, and then gives the hardware simulation and function realization of the system. At the same time, the dynamic scheduling and processing method of the system is simulated and simulated under the environment of Microsoft Visual C 6.0, which shows and verifies the timeliness and effectiveness of the system in dealing with dynamic data.
