为了降低串行生产线的能源消耗,提出了基于可变缓冲区存储量的节能方法。针对缓冲区容量有限及机器失效和修复服从指数分布的串行生产线,考虑节能与产出比率之间的平衡,以产出量作为前提条件,建立了以节能最大化为优化目标的数学模型。考虑机器自身的状态与其上下游缓冲区的实时存储量,提出了基于贪婪算法与概率接受准则的演化迭代算法。最后,进行了仿真试验,结果表明所提的节能方法是有效的、可行的。
In order to reduce the energy consumption of the serial production line, an energy saving method based on variable buffer storage is proposed. Considering the balance between energy saving and output ratio, aiming at the serial production line with limited buffer capacity and machine failure and repair obeyed the exponential distribution, a mathematical model with the maximization of energy conservation as the optimization objective was established based on the output. Considering the state of the machine and the real-time storage capacity of upstream and downstream buffers, an evolutionary iterative algorithm based on greedy algorithm and probability acceptance criterion is proposed. Finally, simulation experiments are carried out, the results show that the proposed energy saving method is effective and feasible.
