REAPING DATE ADJUSTMENT SYSTEM AND COMPUTER PROGRAM

To provide a technique capable of assisting making of a reaping plan during tea harvesting at tea manufacturing plant with consideration given to an appropriate reaping period, plant processing performance, etc.SOLUTION: This technique comprises: a first prediction device that predicts a temporary reaping date or the like from a day of germination; and a second prediction device that predicts a reaping date more appropriate than the temporary reaping date on the basis of growth data obtained on a day calculated from the temporary reaping date or the day of germination. At the second prediction device, making of a plan having the temporary reaping date adjusted to a more appropriate reaping date can be assisted so as to prevent a predicted yield when reaping is carried out on the temporary reaping date from exceeding a plant processing quantity maximum value per day.SELECTED DRAWING: Figure 3 【課題】製茶工場において茶期中の摘採計画を、摘採適期と工場の処理能力等を考慮した計画を策定することを支援できる技術を提供する。【解決手段】萌芽日から仮の摘採日等を予測する第一予測装置と、仮の摘採日または萌芽日から算出した日に取得した生育データに基づいて、仮の摘採日よりも適切な摘採日を予測する第二予測装置とを備え、第二予測装置では、仮の摘採日に摘採した場合の予測収量に対して、一日あたりの工場処理量最大値を超えないように、仮の摘採日をより適切な摘採日へ調整した計画を策定することを支援できる技術。策定する。【選択図】図３
