【摘要】：同时包含装配单元及物料储运环节的定制型装备制造系统,由于装配工序的同时性约束和物料的随机批量运输之间存在耦合作用,用传统的建模方法描述时容易产生状态空间的维数灾难。为此提出一种基于带阻塞的有限缓存开排队网建模方法。基于连续时间马尔可夫链的原理,建立了系统各节点对应的状态空间模型及状态转移平衡方程。应用迭代算法求解状态转移平衡方程组,获得系统各稳态状态的概率分布,并给出系统性能指标值的计算方法。最后进行算例求解并与仿真模型的结果进行比较分析,验证了状态空间分解法求解模型的精确性,从而为系统资源的优化配置提供了基础。
[Abstract]:A customized equipment manufacturing system, including assembly unit and material storage and transportation, has a coupling effect between the simultaneity constraint of the assembly process and the random batch transportation of the material. The dimension disaster of the state space is easily generated when the traditional modeling method is described. Network modeling method. Based on the principle of continuous time Markov chain, the state space model and state transfer equilibrium equation corresponding to each node of the system are established. The iteration algorithm is used to solve the state transfer equilibrium equation, and the probability distribution of the system steady state is obtained, and the calculation method of the system performance index value is given. Finally, the calculation example is carried out. The solution is compared with the results of the simulation model, and the accuracy of the state space decomposition method is verified, which provides the basis for the optimal allocation of the system resources.
