摘要:: 在文献[7]基础上,将不可靠缓冲区引入到不可靠双设备生产线系统中,在离散模型的基础上,系统分析了系统状态概率的变迁情况.采用文献[7]研究方法,猜想系统内部状态概率的形式,代入到内部状态方程,得到满足内部状态方程的解.如果猜想正确,那么必能找到这组解的一个线性组合满足边界条件.通过对系统设备、缓冲区等相关状态概率的处理,降低了问题的求解阶次,探讨并发展了一种评价其系统性能的近似解析方法,给出了其研究算法.仿真结果证明了该方法的有效性.

Abstract:: On the basis of literature [7], the unreliable buffer zone is introduced into the unreliable dual-equipment production line system, and the system state probability change is analyzed on the basis of the discrete model. Using the literature [7] research method, the form of the internal state probability of the system is guessed, and the internal state equation is substituted to obtain the solution satisfying the internal state equation. If the conjecture is correct, then one must find a linear combination of this set of solutions satisfying the boundary conditions. By processing the probability of the relevant states of the system equipment and buffer, the solving order of the problem is reduced, and an approximate analytical method for evaluating the performance of the system is discussed and developed, and the research algorithm is given. Simulation results show the effectiveness of the proposed method.
