论文摘要
精益制造是一种生产方法，旨在减少生产时间，消除浪费，并同步生产与需求的波动。标准的精益制造方法是产品轮，这是各种项目的重复生产顺序。如果此产品轮序序很短，则更容易中断或更改生产以调整需求的故障或波动，因此制造过程更苗条。但是，一个太短的序列会导致从一项生产到另一个项目的经常转换，从而产生更高的成本。这项研究将产品轮方法作为优化问题制定，并提出了两种解决此问题的方法：一种是通过放松到整数线性编程的放松，另一种是通过模拟退火的概率优化技术。我们通过模拟评估了这两种方法的性能，并分析生产倾向与成本之间的关系。
Lean manufacturing is a production method focused on reducing production times, eliminating waste, and synchronizing production with fluctuating demand. A standard lean manufacturing methodology is the product wheel, a repeating sequence of production of various items. If this product wheel sequence is short, it is easier to interrupt or alter production to adjust for failures or fluctuations in demand, so the manufacturing process is leaner. However, a sequence that is too short results in frequent changeover from the production of one item to the next, yielding higher costs. This study formulates the product wheel methodology as an optimization problem and proposes two approaches to solving this problem: one via a relaxation to integer linear programming, and another via the probabilistic optimization technique of simulated annealing. We assess the performance of these two approaches through simulations and analyze the relationships between production leanness and costs.
