Sodium hypochlorite bleaching washing process has been broadly carried out in denim garment industrial production. However, the quantitative relationships between process variables and bleaching performances have not been illustrated explicitly. Hence, it is impractical to determine values of the variables that can achieve the optimal production cost while satisfying the requirements of customers. This paper proposes an optimization methodology by combining ensemble of surrogates (ESs) with particle swarm optimization (PSO) to optimize production cost of chlorine bleaching for denim. The methodology starts from the data collections by conducting a Taguchi L25 (56) orthogonal experiment with the process variables and metrics for evaluating bleaching performances. Based on the data, the quantitative relationships are separately constructed by using RBFNN, SVR, RF and ensemble of them. Then, accuracies of the surrogates are evaluated and it proves that the ESs outperforms the others. Later, the production cost optimization model is proposed and PSO is utilized to solve it, while a case study is given to depict the optimization process and verify the effectiveness of the proposed hybrid ESs-PSO approach. Overall, the ESs-PSO approach shows great capability of optimizing production cost of sodium hypochlorite bleaching washing for denim.

代用集合与粒子群优化相结合的牛仔布次氯酸钠漂白水洗成本优化
次氯酸钠漂白水洗工艺已广泛应用于牛仔服装工业生产中。然而,工艺变量和漂白性能之间的定量关系尚未明确说明。因此,确定能够在满足客户要求的同时实现最佳生产成本的变量值是不切实际的。本文提出了一种通过将代理集合 (ES) 与粒子群优化 (PSO) 相结合来优化牛仔布氯漂白的生产成本的优化方法。该方法从数据收集开始,通过使用用于评估漂白性能的工艺变量和指标进行田口 L25 (56) 正交实验。根据数据,利用RBFNN、SVR、RF和它们的集成分别构建定量关系。然后,评估代理的准确性,并证明 ES 优于其他 ES。随后,提出了生产成本优化模型并利用粒子群算法对其进行求解,同时给出了一个案例研究来描述优化过程并验证所提出的混合 ESs-PSO 方法的有效性。总体而言,ESs-PSO 方法在优化牛仔布次氯酸钠漂白洗涤的生产成本方面表现出极大的能力。同时给出了一个案例研究来描述优化过程并验证所提出的混合 ESs-PSO 方法的有效性。总体而言,ESs-PSO 方法在优化牛仔布次氯酸钠漂白洗涤的生产成本方面表现出极大的能力。同时给出了一个案例研究来描述优化过程并验证所提出的混合 ESs-PSO 方法的有效性。总体而言,ESs-PSO 方法在优化牛仔布次氯酸钠漂白洗涤的生产成本方面表现出极大的能力。
