26、 yield.在作业现场最好的条件下估计直接人工工时，这要排除可能会降低有效劳动产出的所有因素。Example3-1；Effects of job size on productivity作业规模对生产力的影响A contractor has established that under a set of “standard” work conditions for building construction, a job requiring 500,000 labor hours is considered standard in determining the base labor pro

27、ductivity.承建商已建立了一套“标准” 建筑施工的工作条件，一项工作需要50 万人工工时被认为是确定基本劳动生产率的标准。All other factors being the same, the labor productivity index will increase to 1.1 or 110% for a job requiring only 400,000 labor-hours. 所有其他因素相同，一项工作只有40 万人工工时时，劳动生产率指数将上升至1.1或 110。Linear relation: 线性关系假如所需300000-700000 工时之间存在线性关系，如图
