前記差異を出力手段に出力させる出力制御手段とを備える。
上記の積付支援装置と、
前記出力手段を含む端末装置とを備える。
積付空間に複数の荷物を積み付けるための積付計画と、前記複数の荷物の一部又は全部が実際に積み付けられた前記積付空間の状況である積付状況と、の差異を求め、
前記差異を出力手段に出力させる。
コンピュータに、
上記の積付支援方法を実行させるためのものである。
図1では、トラックの荷台内部にて予め定められた積付空間101を上方から見た例を示している。積付空間101の近傍(図1では、積付空間101の左方)には、荷物置場103が設けられている。荷物置場103は、積付空間101に積み付けられる荷物102が一時的に置かれる場所である。荷物置場103には、例えば、図示しないコンベア、フォークリフト、台車などによって荷物102が運ばれてくる。
積付支援システム100は、計測器104と、端末装置105と、積付計画を作成すること等によって積付空間101への複数の荷物102の積み付けを支援する積付支援装置106とを備える。
計測器104は、積付計画に従って荷物102が積付空間101に積み付けられたか否かを判断するための計測を行い、計測した結果を含む計測情報を生成して出力する。
計測器104は、物理的には例えば、積付現場を撮影する3D(Dimension)カメラである。計測器104としての3Dカメラは、積付空間101を含む積付現場を撮影した画像を示す画像情報と、3Dカメラから当該画像に含まれる被写体までの距離を示す距離情報とを同時に生成する。このような3Dカメラによって同時に生成された画像情報及び距離情報は、上述の計測情報の一例である。
端末装置105は、上述の通りネットワークNを介して積付支援装置106と通信する装置であって、物理的には例えば積付現場に設置される汎用のコンピュータである。端末装置105は、第1出力部107と、第1入力部108とを備える。
積付支援装置106は、上述の通り、積付空間101への複数の荷物102の積み付けを支援する装置である。積付支援装置106は、図2に示すように、第2出力部109と、第2入力部110と、荷物記憶部111と、状況取得部112と、状況分析部113と、アルゴリズム記憶部114と、初期計画部115と、計画修正部116と、評価取得部117と、更新部118と、出力制御部119と、を備える。
積付支援装置106は、物理的には例えば、汎用のコンピュータなどである。
本実施の形態に係る積付支援システム100は、積付空間101への荷物102の積み付けを支援するための積付支援処理を行う。積付支援処理は、積付計画生成処理、積付計画修正処理、更新処理を含む。
初期計画部115は、アルゴリズム記憶部114に保持された複数の積付アルゴリズムのうち、初期の積付計画を生成するために用いられる積付アルゴリズムを特定するための積付アルゴリズムの指定を取得する(ステップS104)。
状況取得部112は、ステップS202にて取得した積付状況情報に含まれる積付荷物情報に基づいて、積付空間101に新たに積み付けられた荷物102bがあるか否かを判断する(ステップS203)。
計測器104は、荷物102の荷物情報111a、荷物102を搬入する搬入作業員又は搬入機器の動作情報(いつ、どこで、どのような動作を行っていたかを示す情報)をさらに計測してもよい。また、このような情報が、作業員によって第1入力部107に入力されてもよい。
実施の形態では、計測器104は、積付空間101の形状、サイズ等を計測する例により説明した。しかし、差異を求めるために、荷物情報111aが参照されてもよい。
例えば、計測器104と状況分析部113により求めた積付状況を、新たな積付アルゴリズム(モデル)のモデル化に利用してもよい。熟練者の積付作業にて求められた積付状況から積付アルゴリズムを作成した場合、この積付アルゴリズム(モデル)は、熟練者の積み込みの暗黙知的な積込計画を出力することができる。これは、熟練者の積付作業員が行った積付を手本となる教材として、若手の積付との比較を行いたい際に有効である。
図11は、変形例4に係る積付支援装置306の構成例を示す図である。積付支援装置306は、例えば、状況分析部313と、出力制御部319と、を備えてもよい。
