| 针对再制造系统在不确定性环境下产生瓶颈漂移,导致能耗瓶颈工序难以识别的问题,在阐述废旧产品回收的不确定性的基础上,考虑各工序加工时间以及加工功率的动态变化,提出了增值能耗这一能耗瓶颈指数;通过Arena软件模拟仿真再制造车间的加工工艺路线,对系统能耗瓶颈指数进行实时监测,分析系统能耗瓶颈指数及其波动性,实现能耗瓶颈漂移的可视化,揭示能耗瓶颈漂移规律.采用正交试验方法研究不确定性因素改变对系统能耗瓶颈的敏感性分析.以发动机连杆再制造系统为例,进行能耗瓶颈漂移的案例研究.结果表明:能耗瓶颈指数和能耗瓶颈漂移分析方法能够为再制造系统能耗瓶颈判定和能耗瓶颈漂移特性的分析提供准确和有效的理论基础. |
| 英文摘要: |
| Given bottleneck shifting in a remanufacturing system under uncertainties would result in increasing difficulty of energy bottleneck operation identification. Considering a dynamic variation of processing time and power at each operation based on the description of the uncertainty of returns, an energy bottleneck index named value added energy consumption is proposed. Processing routes of remanufacturing job shop are simulated by the Arena software to realize real-time monitoring of the energy bottleneck index of the system. The analysis of the energy bottleneck index and its fluctuation can realize the visualization of energy bottleneck shifting and reveal the law of bottleneck shifting. The sensitivity analysis of the uncertainty factors to the system energy bottleneck is studied by the orthogonal test. The connecting rod remanufacturing is taken as an illustrative example to conduct the investigation of bottleneck shifting. The results indicate that the energy bottleneck index and energy bottleneck shifting method can provide an accurate and effective theoretical basis for energy bottleneck identification and shifting properties analysis. |
