针对建设项目追求质量最优、工期最短、费用最低、资源使用最均衡并体现出安全施工和工程风险信息的目标,从灰色关联的基本原理出发,通过计算网络计划中各可行方案与虚拟最优方案的安全、质量、费用、工期集成的灰色关联度,得出方案的优劣排序,对工程项目管理具有实际的应用价值. According to the basic principle of gray relation, this paper, through the calculation of each feasible scheme and virtual optimality in network planning, aims at the goal of construction project pursuing the best quality, shortest construction period, lowest cost, most balanced use of resources and reflecting the information of construction safety and engineering risk. Program safety, quality, cost, duration of the integrated gray correlation, draw the program merits and demerits, the project management has practical value.
