 note = {pdf, 本論文は測定システム分析の１つである、測定器の繰返し性と再現性の評価方法としてのゲージR&R（Gauge Repeatability and Producibility）の有効性を述べる．ゲージR&Rでは分散や標準偏差などの統計指標を使用しているが、経営視点からも品質マネジメントシステムであるISO9001に基づいて設立されたIATF（International Automotive Task Force）の中で使用が推奨されている．本論文では，3つの測定チーム，10個の製品が用意され，測定器は定規に決定された．各チームには3人の評価者がいる．まず初めに，各評価者は製品の長さを定規で測定した．10個の製品はランダムに測定され，測定は3回実施された．3人の評価者と10個の製品と3回の測定から90個の測定データが得られた．次に分散分析を行い，評価者，製品，測定ばらつきの標準偏差が推定された．最終的にはゲージR&Rが算出され，測定精度が評価された．経営視点から，ゲージR&Rの結果は3チーム及びチーム内の3人の能力差を表わしている．ここで，もしゲージR&Rの能力が低く，長さ測定が正確に行えないとしたら，測定システムの改善が必要となる．これは重要なマネジメントにおける課題であり，このことについて本論文の最終章において考察することでゲージR&Rの有効性を示した．, This paper describes the effectiveness of Gage Repeatability and Reproducibility, Gage R&R, which is one of the evaluation methods of Measurement System Analysis, MSA. In MSA, many statistical quality control（SQC）methods are recommended. Gage R&R uses statistical indices such as variance and standard deviation. Gage R&R method is introduced in IATF（International Automotive Task Force）standards which was established according to ISO9001. In this paper, three measurement teams were organized, ten products were prepared, and a ruler was decided on as the instrument of measurement. In every team, there were three appraisers. First, in each team, every appraiser measured the length of the products by ruler. The ten products were measured at random, and the measurements were repeated three times. Three appraisers and ten products measured three times produced ninety measurement data for each team. Next, analysis of variance was executed and standard deviation of the appraisers, products, and measurement variations were estimated. Finally, Gage R&R was calculated and checked to determine whether Gage R&R was adequately accurate. The result of Gage R&R showed the difference of performance among three teams and three appraisers in each team. If Gage R&R is too large or inaccurate to measure the length of the product, it is necessary to improve the measurement system. From a management point of view, that is the most important management issue and discussed in final chapter of this paper.},
