摘　　要：为提高混流装配线物流系统的可靠性,在各工位间需设置缓冲区。缓冲区容量是影响生产线性能指标的重要因素,在分析缓冲区功能的基础上,提出了生产线缓冲区的类型和结构,建立了自动导引车和自动化仓库存取系统构成的物流系统工作流程,利用马尔科夫链状态转移方程建立了基于AGV和AS/RS的装配线闭环物流系统数学模型,分析了缓冲区容量参数、AGV数量及生产线性能指标。实例计算表明,该模型方法与物流系统参数的正确性,满足了混流装配线对物流配送系统的要求。The buffer is introduced between each station in order to improve the reliability and the productivity of logis- tics system for the mixed assembly line. Buffer capacity is an important factor affecting the production line performance indi- cators. The type and structure are elaborated based on analyzing the buffer function. The working procedure of the material handling system with the automatic storage retrieval system and automated guided vehicle is built. The closed-loop queuing network model using is developed using queuing theory based on Markov process. The buffer capacity and the states of work station are analyzed. Examples of calculations show that the model and buffer settings are reasonable which could meet the requirements for the mixed assembly line logistics system.
