摘要
本文首先建立在实际生产中应用较广的串联生产线和装配生产线的新的代数模型(在新的代数系下)。基于这类模型,在扰动幅度大小没有任何限制的情况下,对平均服务时间的扰动,建立扰动传播的数学方程,给出系统输出率对平均服务时间的灵敏度公式。仿真结果验证了理论分析结果,其精度令人满意。
Based on a new kind of models for manufacturing systems, Some mathematical equations of perturbation propagation are developed for the perturbation analysis of systems without limitations of scope of perturbation. The formula of sensitivity (throughput of systems with respect to mean service time) is then derived, from which the sensitivity information is calculated with exciting high precision. This information can be used for the optimization of manufacturing systems. Some simulation experiments are given to validate the analyses.
