摘要
用实例介绍了时间─—费用折衷法在提高回采面工效中的应用。通过实测、分析建立线性规划模型，用计算机解算求出在增加费用最低的情况下，各工序所需应急的时间，从而为决策者提供了快速决策方法，使用简便易行。
In this paper,a method of time-cost trade-offs used for raising work efficiency of a coal face was introdced with a real example. A LP mbdel was constructed by the observation and analysis of the coalface and the crash times needed by all activities are calculatedwith a computer under the condition of the total minimum cost incremcents.It provided aquick decision-makimg method for decision-makers,This method is simple and convenient In use.
