摘要
针对云平台下多订单在多企业多时段的协同生产计划问题,引入订单拆分数和订单最小分解率这两个调节变量,在考虑生产时间窗和生产能力等约束下建立协同生产计划模型.同时,设计双层编码,并运用自适应模拟退火遗传算法在不同数据规模下对模型进行求解,求解结果与商用优化软件CPLEX进行比较.最后对模型中的关键参数进行了灵敏度分析,实验结果为云制造平台运营决策者提供决策依据.
In cloud manufacturing platform,a multi-plants and multi-periods collaborative production problem was discussed by introducing two adjustive variables,which are the maximal number of enterprises that process an order and the minimal order splitting ratio,respectively.We established a collaborative production planning model with constrains of production time window and production capacity.Then,a self-adaptive simulated annealing genetic algorithm using bi-level code was designed.Our proposed approach was compared with a commercial optimization software CPLEX under different data sizes in numerical simulation.Lastly,the sensitivity analysis of the major parameters in the model was carried on.The experimental results provide a decision-making basis for operation decision makers of cloud manufacturing platform.
