Abstract: In estimation of a task scale, information on the start and completion dates of a task, non-operation information such as holidays and information on man-days of other task plans are used to attain high-precision estimation. The number of man-days is estimated from the task scale for the next week by referring to the productivity of the task plan, the productivity of the task actual results and the maximum, minimum and average of productivity of the past task actual results to improve the estimation precision. The scheduled completion date is predicted from the information of the task scale and the number of man-days planned for the next week and the task actual results, so that delay is expressed quantitatively.
