将JIT (Just In Time)思想带到工程建设过程中,以准时率为基础建立其相应的评价指标体系,构建评价模型,并以南方电网公司的数据为基础,设定相应的权重。最后通过溯源分析寻找出其JIT工作中的薄弱环节,提出合理且有针对性的建议。 Just In Time (JIT) thought is brought into the project construction process. We establish the cor-responding evaluation index system based on time rate, and construct the evaluation model. Fur-thermore, based on the data of Southern Power Grid Co., Ltd, we set up the corresponding weights factor. At last, by tracing analysis we find out the weak link of JIT work, and put forward reasonable and targeted suggestions.
