【摘要】：针对炉次加工时间可变条件下的废钢铁再制造生产调度问题,考虑到炉次在生产车间的实际生产过程中具有随机性与模糊性,根据不确定理论对炉次加工时间进行模糊化处理,在碳排放约束下构建了加工时间可变的废钢铁再制造生产调度模型,提出了加工时间的调整方法并设计人工智能算法进行了求解。最后结合算例,比较分析了加工时间调整方法对碳排放约束条件下加工时间可变的废钢铁再制造生产调度问题的影响,并得到:1加工时间调整方法平均每次可以减少炉次等待时间61.71%,减少炉次等待产生的碳排放63.79%,单次实验使得炉次等待时间显著减少的概率为60%及以上;2在不改变makespan的前提下,加工时间调整可以降低炉次等待时间的波动程度,使废钢铁再制造的生产过程更加平稳;3对于碳排放约束下加工时间可变的废钢铁再制造生产调度问题,通过加工时间调整方法减少炉次等待时间,可以减弱碳排放约束的作用,为提高算法效率提供了可能。
[Abstract]:Considering the randomness and fuzziness of the furnace times in the actual production process of the workshop, according to the uncertainty theory, the remanufacturing scheduling problem of scrap iron and steel under the condition of variable furnace processing time is analyzed. The fuzzy processing time of the furnace is fuzzied according to the uncertainty theory, considering the randomness and fuzziness of the furnace times in the actual production process of the workshop. A production scheduling model of scrap steel remanufacturing with variable processing time was constructed under the carbon emission constraint. The adjustment method of processing time was put forward and the artificial intelligence algorithm was designed to solve the problem. Finally, the effect of processing time adjustment method on remanufacturing scheduling problem of scrap iron and steel with variable processing time under the condition of carbon emission constraint is compared and analyzed with an example. The results are as follows: (1) the processing time adjustment method can reduce the waiting time 61.71 per time, and reduce the carbon emission 63.79 produced by the furnace waiting time. The probability that the waiting time is significantly reduced by 60% or more is achieved by a single experiment. (2) under the premise of not changing makespan, the adjustment of processing time can reduce the fluctuation degree of waiting time of furnace times, and make the production process of scrap iron and steel remanufacturing more stable; 3 for the remanufacturing scheduling problem of scrap iron and steel with variable processing time under carbon emission constraints, the effect of carbon emission constraint can be weakened by reducing the waiting time of the furnace by adjusting the processing time, which provides the possibility for improving the efficiency of the algorithm.
