Abstract To maximize the potential of success for a large-scale mine construction project, rigorous scheduling must be employed. Given that the mineral industries are cyclical (due to global supply and demand imbalance, inconsistent growth periods, and technological innovation), timing of a mining construction project has a significant impact on the project. The cost of delays in the project can be devastating if the high prices of the cycle are missed. In this paper, a method is proposed to schedule large projects using a combination of the Critical Path Method (CPM) and Linear Programming (LP) to maximize the value of a construction mega-project. The method is applied to a mine construction project including 80 activities with complex precedence relationships. The critical path for the mine construction is crashed to a minimum duration of 234 weeks at optimality (down from the 263-week base case), providing a net present value (NPV) of $901,772,160 (an improvement of $127 million over the base case).

价格周期性下的综合矿山建设项目规划

摘要 为了最大限度地提高大型矿山建设项目的成功潜力，必须采用严格的调度。鉴于矿产行业具有周期性（由于全球供需失衡、增长周期不一致和技术创新），矿业建设项目的时机对项目有重大影响。如果错过周期的高价，项目延迟的成本可能是毁灭性的。在本文中，提出了一种使用关键路径法 (CPM) 和线性规划 (LP) 相结合的方法来安排大型项目，以最大化大型建筑项目的价值。该方法应用于一个矿山建设项目，包括80个具有复杂优先关系的活动。
