To support identifying highly relevant features that affect product quality.SOLUTION: A quality influencing factor identification support device includes: a data collection unit 1 that collects product quality data and process data of batch processes; a storage unit 2 that stores the product quality data and the process data; a feature extraction unit 3 that extracts features of the process data: a feature classification unit 4 that groups all features based on the similarity between features; a representative feature quantity selection unit 5 that selects representative feature quantities for each group based on the relationship with product quality data for each group; a candidate identification unit 6 that identifies the representative features that contribute to the fluctuation of product quality data among the representative features as quality influencing factor candidates; and a specific result notification unit 7 that notifies the user of a specific result of the quality influencing factor candidate.SELECTED DRAWING: Figure 1 【課題】製品品質に影響を与える妥当性の高い特徴量を特定することを支援する。【解決手段】品質影響因子特定支援装置は、バッチプロセスの製品品質データとプロセスデータを収集するデータ収集部１と、製品品質データとプロセスデータを記憶する記憶部２と、プロセスデータの特徴量を抽出する特徴量抽出部３と、全ての特徴量を特徴量同士の類似度に基づいてグループ化する特徴量分類部４と、各グループについて製品品質データとの関係に基づいて代表特徴量をグループ毎に選択する代表特徴量選択部５と、代表特徴量の中から製品品質データの変動に対して寄与する代表特徴量を品質影響因子候補として特定する候補特定部６と、品質影響因子候補の特定結果をユーザに通知する特定結果通知部７を備える。【選択図】 図１
