【摘要】：伴随着信息技术的快速发展以及贸易全球化进程加速，光电通信行业也迎来更大的机遇与挑战，企业为了保证利润和满足客户个性化需求必须保证产品的及时更新。然而，多品种小批量生产环境为企业生产计划与控制带来很大困扰，导致在制品积压严重，产品制造周期居高不下，严重影响企业资金周转与产品交付。本课题以武汉光迅科技股份有限公司作为研究对象，试图通过深入的分析研究，，探索能够更好适应多品种小批量生产环境的生产计划与控制机制，以增加企业在新环境下的竞争实力。首先结合光迅公司外部环境与内部状况，剖析现有生产计划与控制体系的缺陷，进而有针对性的从产能规划与协调、车间作业计划、生产绩效评估三个环节进行优化研究。产能规划与协调方面，通过规范产能规划流程和建立产能关联表来实现人力和设备需求的快速、准确评估。车间作业计划方面，运用约束理论和数据模型与决策，提出多品种小批量环境下车间作业计划的设计原则与思路，实现产能瓶颈识别与控制、前拉后推式的车间生产计划控制机制。生产绩效评估方面，改变原有的单一指标效率评估机制，运用OPE综合效率对时间损失进行分层分析，为改善工作提供方向和依据。论文最后进行结论与展望，总结了光迅公司生产计划与控制系统的改进成果，以及研究过程中遇到的问题，从而为将来研究提供方向。
[Abstract]:With the rapid development of information technology and the acceleration of the process of trade globalization, the photoelectric communication industry also ushered in greater opportunities and challenges. In order to ensure profits and meet the personalized needs of customers, enterprises must ensure the timely updating of products. However, the multi-variety and small-batch production environment brings a lot of trouble to the production planning and control of enterprises, which leads to a serious backlog of in-process products and a high production cycle, which seriously affects the capital turnover and product delivery of enterprises. Taking Wuhan Guangxun Science and Technology Co., Ltd. as the research object, this paper attempts to explore the production planning and control mechanism that can better adapt to the multi-variety and small-batch production environment through in-depth analysis and research. In order to increase the competitive strength of enterprises in the new environment. Firstly, combined with the external environment and internal situation of Guangxun Company, the defects of the existing production planning and control system are analyzed, and then the optimization research is carried out from three aspects: capacity planning and coordination, workshop job plan and production performance evaluation. In terms of capacity planning and coordination, rapid and accurate assessment of manpower and equipment requirements is achieved by standardizing production planning processes and establishing capacity correlation tables. In the aspect of workshop scheduling, by using constraint theory, data model and decision, this paper puts forward the design principle and thought of workshop job plan in multi-variety and small batch environment, and realizes the identification and control of productivity bottleneck. Pre-pull-back-push workshop production planning control mechanism. In the aspect of production performance evaluation, the former single index efficiency evaluation mechanism is changed, and the OPE comprehensive efficiency is used to analyze the time loss in order to provide the direction and basis for improving the work. Finally, the conclusion and prospect are given, and the improvement results of the production planning and control system of Guangxun Company are summarized, as well as the problems encountered in the course of the research, so as to provide the direction for the future research.
