缓冲区型串行生产作业系统的Cohen模型

Cohen Model for Serial Manufacture System With Finite infinite or Combined Buffers

本文以极大代数为工具，通过模块点阵，对缓冲区容量有限、无限或组合型串行生产作业系统建立了统—的、以作业区间为状态的状态空间模型——Ｃｏｈｅｎ状态空间模型．该模型简洁直观，其参数矩阵可以宜接到写，还给出了一个模型求解与系统动态特性分析的算例．

Using Max-Algebra and Block Array, this paper presents explicit, unified state equations based on task intervals, which is established for serial manufacture systerm with finite,infinite or combined buffers, And equations have the same characteristic with Cohen Model and can be written directly, This paper also presents an example and its dynamic characteristic analysis,
