To provide a tire wear-amount estimation system and a computation model operation model that select a computation mode when operating, and can maintain the provision of wear-amount estimation data.SOLUTION: In a tire wear-amount estimation system 100, a data acquisition unit 12 acquires data of an explanatory variable including a numerical variable and a category variable about a vehicle and a tire 7 mounted to the vehicle. A wear-amount calculation unit 14 has a missing value corresponding computation model 14a and a missing value non-corresponding computation model 14b to which the data acquired by the data acquisition unit 12 is input, and is configured to calculate a tire wear-amount. A determination unit 13 is configured to determine whether or not a non-learning category variable is included in the data acquired by the data acquisition unit 12. The wear-amount calculation unit 14 is configured to calculate the tire wear-amount using one of the missing value corresponding computation model 14a and the missing value non-corresponding computation model 14b on the basis of a determination result by the determination unit 13.SELECTED DRAWING: Figure 1

    【課題】運用時に演算モデルを選択し、摩耗量推定データの提供を維持することができるタイヤ摩耗量推定システムおよび演算モデル運用方法を提供する。【解決手段】タイヤ摩耗量推定システム100において、データ取得部12は、車両および車両に装着されたタイヤ7に関する数値変数およびカテゴリ変数を含む説明変数のデータを取得する。摩耗量算出部14は、データ取得部12により取得されたデータを入力する欠損値対応演算モデル14aおよび欠損値非対応演算モデル14bを有し、タイヤ摩耗量を算出する。判定部13は、データ取得部12により取得されたデータに未学習のカテゴリ変数が含まれているか否かを判定する。摩耗量算出部14は、判定部13による判定結果に基づいて、欠損値対応演算モデル14aおよび欠損値非対応演算モデル14bのうち一方を用いてタイヤ摩耗量を算出する。【選択図】図1
