摘　　要：大型产品的生产往往需要在不同的生产线上进行,各生产线之间构成了上下游结构关系,给生产计划的制定带来新的问题。研究了一类带有限缓冲区的上下游生产线协调生产计划的模型,建立了上下游生产线部件成品关联结构,并根据该关联结构建立了一种多生产线协调效益计划模型。通常情况下,该模型是非线性的并且维数将很大。为了便于求解,提出了一种快速的求解方法——模型分解方法。该方法可以将原来的高维模型分解成若干个较小规模的模型,从而可以大大地提高求解速度。仿真结果表明,该方法可以方便对此类模型进行求解,是有效可行的。Since the manufacture of large-scale products is made through different lines and there is an up-down interaction structure among the lines, a new problem for production planning is therefore brought out. A harmonious model of production planning for a class of up-down lines with limited buffers is studied and an interaction structure for the products is presented. A harmonious benefit planning model for multiple-product-line is built up. The model is usually non-linear with a very large dimension, so a rapid algorithm-model decomposition method is put forward. The method decomposes the highly dimensional model into several small ones with lower dimension so as to increase calculation speed. Simulation results show that the proposed algorithm is efficient and feasible.
