本文针对大型工程建设管理，提出了基于网络计划的由计算机实现的进度和投资控制管理模型，它以工程设计产生的网络计划为基准，并根据具体施工情况综合分析，得到每一施工年度各个施工单位的工程量和投资，通过年度工程量和投资计划，严格控制工程的进度和投资，保证工程质量和工程工期，并实现投资最优。

In view of the complication, multitude and importance of the large engineering construction management, the paper presented a new model of process and invested management based on engineering network plan. According to the engineering design and synthetically analyzing the construction situation, getting annual amount and invest plan, the model strictly control the process and cost of the engineering construction to guarantee Goth engineering scheduled time and engineering quality, and optimize the cost to the most.
