【摘要】：随着经济的全球化发展,制造企业正面临着更加复杂多变的竞争环境。提高自身的生产管理与控制能力,实现产品的“保质”、“保量”、“及时到位”,是企业立于不败的关键。本文在研究系统可靠性理论与制造企业生产过程控制内涵的基础上,提出了制造企业生产过程控制可靠性的概念,并构建了生产过程控制的可靠性框架。在此框架基础上,本文主要研究生产计划的可靠性与生产制造过程的可靠性。在生产计划可靠性的研究上,本文提出了可靠性基础上的企业生产能力计算方法；运用模糊评价法对客户重要度进行了评估；对客户订单的潜在收益进行了数学建模分析；运用蒙特卡洛技术对订单交货期的可靠性进行了定量分析。在生产制造过程可靠性的研究上,首先,研究了生产制造过程中人员、设备、环境的可靠性,并运用马尔科夫过程法对人-机-环境系统的可靠性进行了定量研究,得出了生产环境变化下,人-机-环境系统的可靠度计算公式。其次,本文研究了生产物流的可靠性,在物料的数量研究上,本文研究了基于可靠性的在制品库存控制,得出了最小安全库存的计算公式,并提出了基于节拍控制的库存补给策略,同时对生产线的整体可靠性进行了研究。在物料的质量控制研究上,本文主要提出了基于质量经济性的过程能力指数的确定方法。制造企业生产过程控制可靠性的研究涵盖诸多方面的内容,本文主要对其中的生产计划、人-机-环境系统、生产物流方面进行研究,研究结果可为企业提高生产过程控制能力、提高竞争实力,提供理论依据与参考。
[Abstract]:With the development of economic globalization, manufacturing enterprises are facing a more complex and changeable competitive environment. It is the key for the enterprise to improve its production management and control ability and realize the product's "quality", "quantity retention" and "timely delivery". On the basis of studying the theory of system reliability and the connotation of manufacturing process control, this paper puts forward the concept of manufacturing enterprise production process control reliability, and constructs the reliability framework of production process control. On the basis of this framework, this paper mainly studies the reliability of production planning and manufacturing process. On the research of reliability of production plan, this paper puts forward the method of calculating enterprise productivity on the basis of reliability, evaluates the importance of customer by using fuzzy evaluation method, and makes mathematical modeling and analysis on the potential profit of customer order. The reliability of order delivery date is quantitatively analyzed by Monte Carlo technique. In the research of the reliability of manufacturing process, firstly, the reliability of people, equipment and environment in manufacturing process is studied, and the reliability of man-machine-environment system is quantitatively studied by Markov process method. The formula for calculating the reliability of man-machine-environment system under the change of production environment is obtained. Secondly, the reliability of production logistics is studied in this paper. In the research of material quantity, this paper studies the in-process inventory control based on reliability, and obtains the calculation formula of minimum safety inventory. The inventory replenishment strategy based on rhythm control is put forward, and the overall reliability of production line is studied. In the research of material quality control, this paper puts forward a method of determining process capability index based on quality economy. The research on the reliability of production process control in manufacturing enterprises covers many aspects. In this paper, the production planning, man-machine-environment system, production logistics are studied. The results can provide theoretical basis and reference for enterprises to improve their production process control ability and competitive strength.
