摘要： PROBLEM TO BE SOLVED: To provide a quality prediction device predicting quality with high accuracy from a number of operating variables.SOLUTION: Based on process operation data and quality data, operating variable space having the operation data as a base vector is divided into a plurality of local areas, and an activity function is calculated for calculating a contribution ratio to the totality of a local relational expression indicating relations between quality and operating variables in each local area based on the operation data, to determine a coefficent of the local relational expression by minimizing the weighting sum of a first item indicating magnitude of a prediction error in a quality prediction value and a second item indicating magnitude of the coefficient of the local relational expression. Further, mathematical models indicating relations between the operating variables and the quality are derived as superposition of the local relational expression and the local area with the activity function so as to select the minimum error mathematical model among a plurality of division patterns of mathematical models. If an error of the minimum error mathematical model is greater than a convergence determination variable of a given condition, the operating variable space is to be subdivided again and the respective steps are to be repeated to display a mathematical model of a convergence result as an analysis result.

摘要： PROBLEM TO BE SOLVED: To perform quality prediction with high accuracy in a manufacturing process which has characteristic which is non-linear and fluctuated timewisely and in which the ease of understanding of a relational formula is required. SOLUTION: The whole operation range of the manufacturing process is divided into a plurality of local regions, a local relation formula is prepared in each local region and a nonlinear characteristic is predicted with high accuracy in order to construct the whole relational formula by their combination. The relationship between operation variables and the quality variables is readable from the constitution of the whole relation formula and the value of coefficient of each local relational formula by humans. Furthermore, when the predicting accuracy of the local relation formula is deteriorated by the change of the relationship between the operation variable and the quality variable, the coefficient of the local relational formula is renewed so as to reduce the predicting error.
