A requirements planning system for the Space Shuttle Operations schedule
针对NASA在1980年代每年最多30次航天飞机发射的复杂排程问题，传统PERT模型无法解决多项目资源冲突，本文提出并被NASA采纳的需求规划系统。
Abstract The National Aeronautics and Space Administration (NASA) is charged with developing a Flight Operations Planning Schedule for Space Shuttle Operations in the 1980s. During this decade, NASA plans to launch up to thirty space shuttle flights per year when the program reaches the mature phase. Traditional planning techniques for space flights (PERT‐type models) are inadequate for this task because of their inability to resolve conflicts arising from multiple demands for limited resources generated by numerous simultaneous projects (space flights). This paper describes a requirements planning system developed by the authors and adopted by NASA for this resource constrained multiple project scheduling problem.
