中文摘要:
      针对零件再制造过程能耗评估困难问题,建立基于图形评审技术(graphical evaluation and review technology,GERT)的能耗模型.首先,分析了零件再制造过程中能耗特性及能耗不确定性的原因,阐述再制造过程各工序能量消耗的一般规律.其次,基于GERT建立了零件再制造过程能耗模型,给出了不同再制造处理方式的概率和期望能耗的计算方法.最终以发动机曲轴的再制造过程为案例对所提出的模型和方法进行了验证,并与Arena软件仿真结果进行了对比分析,验证了结果的合理性.
英文摘要:
      An energy consumption model based on graphical evaluation and review technology (GERT) is proposed with regard to the difficulty in assessing the energy consumption in parts remanufacturing. Firstly, the energy consumption characteristics in parts remanufacturing and the reasons of energy consumption uncertainty are analyzed and the general law of energy consumption in each remanufacturing process is explained. Secondly, the GERT-based energy consumption model for parts remanufacturing is established and the computational approaches for the probability and the expected energy consumption under different remanufacturing treatments are proposed. Finally, an engine crankshaft remanufacturing is taken as an illustrative case to validate the proposed model and method. A comparison with simulation results of Arena software is conducted to testify the feasibility of the results.
