说明：  车间布局优化是将加工设备、物料输送设备、工作单元和通道走廊等布置物体合理地放置在一个有限的生产车间内的过程。车间布局优化模型是一个含有较为复杂约束的非线性连续优化模型，可以使用遗传算法进行优化。
(Workshop layout optimization is the process of processing equipment, material conveying equipment, work unit and corridor and so on, and arranging the objects in a limited production workshop. The job shop layout optimization model is a nonlinear continuous optimization model with more complex constraints, which can be optimized by genetic algorithm.)
