PROBLEM TO BE SOLVED: To provide a yard position determination method and a yard position management system which can accurately acquire information related to the arrangement position of a hull block or a container in a ship building yard and store the information in a data base.SOLUTION: The position of a portable information terminal 2 is measured based on an output of a portable GPS receiver 21 by using the portable information terminal 2 which comprises a display part, an input part, and a portable GPS receiver 21 having lower accuracy than a reference position identifying GPS receiver, and is carried by an operator who moves a hull block or a container. A mutual distance calculation part 22 repeatedly calculates mutual distances between the position of the portable information terminal 2 and the center positions of a plurality of yard areas. A yard position determination part 23 determines the position of the portable information terminal 2 which is the shortest distance among the plurality of mutual distances calculated within a prescribed period as a current position. The yard position determination part 23 determines the yard position including the center position used for determining the current position as a yard position of the hull block or the container.SELECTED DRAWING: Figure 1

    【課題】造船所内における船体ブロックまたはコンテナの配置場所に関する情報を正確に取得しデータベースに記録することができる蔵置位置決定方法及び蔵置位置管理システムを提供する。【解決手段】表示部と入力部と基準位置特定用GPS受信機よりも精度が低い携帯GPS受信機21とを備え、船体ブロックまたはコンテナを移動させる作業を実施する作業者が携帯する携帯型情報端末2を用い、携帯GPS受信機21の出力に基づいて携帯型情報端末2の位置を測位する。相互距離演算部22は携帯型情報端末2の位置と複数の蔵置領域の中心位置との間の相互距離を繰り返し演算する。蔵置位置決定部23は所定期間内に演算をした複数の相互距離の中から最短距離となる携帯型情報端末2の位置を現在位置と特定する。蔵置位置決定部23は現在位置の特定に使用された中心位置を含む蔵置位置を船体ブロックまたはコンテナの蔵置位置として決定する。【選択図】図1
