目前,全球正面临着环境污染、资源短缺、能源供应紧张等诸多不利因素,再制造和循环利用在这一背景下就显得尤为重要。本文以再制造发动机项目的时间管理为研究对象,以工作分解结构方法(WBS)为理论分析主线,以SH汽车制造企业为实践主体,以再制造技术为支撑,对发动机再制造项目整个过程的时间管理进行分析,旨在合理配置时间,安排工期,优化流程,最终实现复原工作性能上达到新机质量和技术标准的发动机。 At present, the world is facing many unfavorable factors such as environmental pollution, shortage of resources and shortage of energy supply. Remanufacturing and recycling are particularly important in this context. In this paper, the time management of remanufacturing engine project is taken as the research object, WBS is the theoretical analysis main line, SH automobile manufacturing enterprise is the main body of practice, remanufacturing technology is the support, the whole process of engine remanufacturing project Time management analysis, aimed at the rational allocation of time, scheduling, optimization process, and ultimately to restore work performance to achieve new machine quality and technical standards of the engine.
