SYSTEM FOR SUPPORTING PRODUCTION AND METHOD OF SUPPORTING PRODUCTION

To provide information which serves as a guideline for determination and operation by a user who is in charge of operation.SOLUTION: A system for supporting production includes: a plurality of sensors for measuring the amount of state and the amount of operation of a production facility; a data collection/management unit which collects and holds time-series data of multiple variables measured by the sensors; a variable definition unit which defines a variable to be analyzed, from the held data and variables measured online; a data forming processing unit and a principal component analysis processing unit which pre-process the variables and perform principal component computation; a variable correlation display unit which executes multivariate analysis for each predetermined cycle, updates analysis values, displays them as time-series information, and displays the time-series information serving as a target index, in conformity with time-series principal component values; a state change definition unit which defines a state change to be subjected to factor variable extraction from multi-time series information; a change factor variable calculation processing unit which executes a factor variable extraction process with a high correlation on the defined state change; and a change factor variable display unit which displays a factor variable related to the extracted state change.SELECTED DRAWING: Figure 4 【課題】オペレーションを行うユーザの判断及び操作を支援するための指針となる情報を提供する。【解決手段】製造設備の状態量または操作量を計測する複数のセンサと、複数のセンサによって計測される複数の変数の時系列データを収集し保持するデータ収集・管理部と、保持されたデータとオンライン計測された変数から、分析の対象とする変数を定義する変数定義部と、変数を前処理し主成分演算するデータ整形処理部および主成分分析処理部と、所定サイクル毎に多変量解析を実行し、分析値を更新し時系列情報として表示し、目標指標となる時系列情報を時系列主成分値に合わせて表示する変数相関表示部と、多時系列情報から要因変数抽出の対象となる状態変化を定義する状態変化定義部と、状定義された状態変化に相関の大きな要因変数抽出処理を実行する変化要因変数算出処理部と、抽出された状態変化に関わる要因変数を表示する変化要因変数表示部と、を備える。【選択図】図４
