改进系统布置设计法在车间布局设计中的应用

现代车间布局设计时，往往应用基于遗传算法（Genetic Algorithm, GA）选择最优布局的系统布置设计（Systematic Layout Planning, SLP）方法。为减少GA中轮盘赌模型随机性的影响，融合熵权-TOPSIS（ET）组合评价模型对GA的选择算子进行重新计算，形成ET-GA模式实现SLP方法的改进。最后，利用改进SLP方法对某车间进行布局设计，结合ET-GA模型的改进SLP方法与原方案、基于GA的SLP方法相比，物料搬运成本分别节约了12.50%、5.88%，非物流关系分别提高了3.72%、2.50%，物料搬运时间分别降低了21.02%、14.75%。

Research on Application of Improved SLP Method in Workshop Layout Planning

Systematic Layout Planning (SLP) method is widely used in workshop layout design, and Genetic Algorithm (GA) is often used to select satisfactory solutions. In order to reduce the influence of randomness of roulette model in GA, we combine the Entropy-TOPSIS (ET) evaluation model to recalculate selection operators of GA, thus ET-GA model is formed to improve SLP method. Finally, the improved SLP method is used for layout design of a workshop. Compared with the original desig and GA-based SLP method, the improved SLP method based on ET-GA model saved material handling cost by 12.50% and 5.88% respectively, increased non-logistics relationship by 3.72% and 2.50% respectively, and reduced material handling time by 21.02% and 14.75% respectively.
