摘要

考虑到大型工业生产中全厂优化的复杂性，提出了一种分布式优化框架来解决乙烯全过程的利润优化问题。为了在保证约束满足的情况下解决物料在生产单元停留时间的延迟问题，提出了一种梯度跟踪的异步分布参数投影算法。此外，该算法还引入了重球动量和Nesterov动量，以实现双加速度特性。实验结果表明，与同步算法相比，异步算法的收敛速度更快。

Distributed asynchronous double accelerated optimization for ethylene plant considering delays

Considering the complexity of plant-wide optimization for large-scale industries, a distributed optimization framework to solve the profit optimization problem in ethylene whole process is proposed. To tackle the delays arising from the residence time for materials passing through production units during the process with guaranteed constraint satisfaction, an asynchronous distributed parameter projection algorithm with gradient tracking method is introduced. Besides, the heavy ball momentum and Nesterov momentum are incorporated into the proposed algorithm in order to achieve double acceleration properties. The experimental results show that the proposed asynchronous algorithm can achieve a faster convergence compared with the synchronous algorithm.
