摘要:随着企业的竞争和生产规模的加大,多项目管理的进行已成为普遍现象。这就需要将关键链项目管理从单项目环境中推向于多项目环境中。本文以中天公司变压器的生产为实例背景,提出关键链多项目管理中关于项目优先级排序的改善后的项目优先评价法,以及关于资源均衡优化的改善方法和相关指标。通过构造公司以两种产品并行生产的多项目环境,将其应用于公司的多项目进度计划中。在依据关键链项目管理实施步骤的基础上,首先根据项目优先评价法得出两个项目的优先级顺序,接着在识别瓶颈工序并制定基于瓶颈工序的多项目进度计划之上,运用改善后的ACTIM方法来解决非关键工序间的资源冲突,接着消除工序的安全时间,在调整后的资源均衡下的多项目进度计划中确定出关键链,最后在链路末端汇入通过综合评估法计算出的缓冲区,确定出改变后的关键链,从而得出公司基于关键链的多项目进度计划,并最终使项目的工期较原前缩短了9.5天。

Research on Transformer Production Schedule Management Based on Key Chain in zhongtian company
Abstract:With the increase in enterprise competition and the scale of production,the implementation of multi-project management has become a common phenomenon. This will require critical chain project management to move from a single project environment to a multi-project environment.Based on the background of transformer production in Zhongtian Company,this paper puts forward the improved project priority evaluation method for item priority ranking in critical chain multi-project management,and the improvement method and related index of resource balance optimization.By constructing a multi-project environment in which the company produces two products in parallel,it is applied to the company's multi-project schedule. Based on the implementation steps of critical chain project management,the priority order of the two projects is first obtained according to the project priority evaluation method. Then,on the basis of identifying the bottleneck process and developing the multi-project schedule based on the bottleneck process,applying the improved ACTIM method to solve the resource conflict between non-critical processes,and then eliminating the safety time of the processes,determining the critical chain in the multi-project schedule under the adjusted resource balance,and finally importing the buffer zone computing through the comprehensive evaluation method to the end of the link to determine the critical chain after the change,consequently,it contributes to a multi-project schedule based on critical chain,and eventually makes the project duration shorter than the original 9.5 days.
