以下、本発明の実施の形態1における、集荷量調整支援装置、集荷量調整支援方法、及びプログラムについて、図1~図4を参照しながら説明する。
最初に、本発明の実施の形態1における集荷量調整支援装置の構成について図1を用いて説明する。図1は、本発明の実施の形態1における集荷量調整支援装置の概略構成を示すブロック図である。
資料:http://ja.wikipedia.org/wiki/%E4%BD%9C%E6%A5%AD%E6%9B%B2%E7%B7%9A
次に、本発明の実施の形態1における集荷量調整支援装置10の動作について図4を用いて説明する。図4は、本発明の実施の形態1における集荷量調整支援装置の動作を示すフロー図である。以下の説明においては、適宜図1~図3を参酌する。また、本実施の形態1では、集荷量調整支援装置10を動作させることによって、集荷量調整支援方法が実施される。よって、本実施の形態1における集荷量調整支援方法の説明は、以下の集荷量調整支援装置10の動作説明に代える。
本発明の実施の形態1におけるプログラムは、コンピュータに、図4に示すステップA1~A7を実行させるプログラムであれば良い。このプログラムをコンピュータにインストールし、実行することによって、本実施の形態1における集荷量調整支援装置10と集荷量調整支援方法とを実現することができる。この場合、コンピュータのCPU(Central Processing Unit)は、傾向線設定部11、推定部12、及び集荷量算出部13として機能し、処理を行なう。
以上のように、本実施の形態1では、集荷量調整支援装置10は、複数の生産者が集出荷場に農産物を持ち込むことを考慮して、傾向線を設定し、これを基準にして集荷量が不足するかどうかを判断する。このため、集荷量調整支援装置10によれば、複数の生産者によって集出荷場に農産物が持ち込まれる態様において、収集される農産物の集荷量を予測することができる。この結果、背景技術の欄で述べた、集荷量不足に伴う問題と集荷量過多に伴う問題との発生が抑制される。
上述したように、図1~図4に示した例では、傾向線として、点P1と点P2とを通る1次関数が設定され、最終的な集荷量が日次予定集荷量Sに満たないと推定される場合に、そのことが管理者40に提示されているが、本実施の形態1は、この例に限定されない。
本変形例2では、各生産者が、端末50を介して、集出荷場に納入する農産物の納入量を、集荷量調整支援装置10に通知を行なうことができる。この場合、管理者40が、一定の基準を満たない農産物の量を入力することで、集荷量算出部13は、通知された納入量から、管理者40によって入力された量を減算して、調製済み集荷量を算出することができる。
次に本発明の実施の形態2における、集荷量調整支援装置、集荷量調整支援方法、及びプログラムについて、図5~図9を参照しながら説明する。

以上のように、本実施の形態2では、集荷量調整支援装置20は、複数の生産者が集出荷場に農産物を持ち込む場合の集荷量の増加傾向を学習し、学習結果を用いて集荷量が不足するかどうかを判断する。このため、集荷量調整支援装置20による場合も、複数の生産者によって集出荷場に農産物が持ち込まれる態様において、収集される農産物の集荷量を予測することができる。この結果、背景技術の欄で述べた、集荷量不足に伴う問題と集荷量過多に伴う問題との発生が抑制される。
上述したように、図5~図9に示した例では、学習データの基準となる傾向線として、点P1と点P2とを通る1次関数が用いられているが、本実施の形態2は、この例に限定されない。
本実施の形態2には、実施の形態1の変形例2を適用することができる。つまり、本実施の形態2においても、各生産者が、端末50を介して、集出荷場に納入する農産物の納入量を、集荷量調整支援装置10に通知を行なうことができる態様であっても良い。また、集荷量調整支援装置20が、調製済み集荷量を記録している外部のシステムに接続されている場合は、本実施の形態2も、調製済み集荷量がこのシステムから自動的に通知される態様であっても良い。
次に本発明の実施の形態3における、集荷量調整支援装置、集荷量調整支援方法、及びプログラムについて、図10を参照しながら説明する。図10は、本発明の実施の形態3における集荷量調整支援装置の具体的構成を示すブロック図である。
本実施の形態3では、図4に示したステップA1~A7、及び図9に示したステップB1~B7のうち、いずれか又は両方が実行されることにより、本実施の形態3における集荷量調整支援方法が実行されることになる。その他に、本実施の形態3では、日毎に、学習データを生成するため、予め時刻毎に乖離率Xを算出するステップ、終了時刻T3において最新の集荷量が「目標」に到達しているかどうかを判定するステップ、算出結果及び判定結果を格納するステップ、が実行される。
本発明の実施の形態3におけるプログラムは、コンピュータに、図4に示すステップA1~A7、及び図9に示すステップB1~B7を実行させるプログラムであれば良い。このプログラムをコンピュータにインストールし、実行することによって、本実施の形態3における集荷量調整支援装置30と集荷量調整支援方法とを実現することができる。この場合、コンピュータのCPU(Central Processing Unit)は、傾向線設定部31、推定部32、終了算出部33、及び学習推定部34として機能し、処理を行なう。
ここで、実施の形態1~3におけるプログラムを実行することによって、集荷量調整支援装置を実現するコンピュータについて図11を用いて説明する。図11は、本発明の実施の形態1~3における集荷量調整支援装置を実現するコンピュータの一例を示すブロック図である。
