1. Select a set of "optimized" design points.
2. Add a design point to an existing design.
3. Improve the expectations of the existing design D.
4. Evaluate and compare design schemes.

1, standard
A, D- Optimality: Select this option to select a suitable D point from a group of candidate points, and the design scheme selected according to this standard can minimize the variation in the regression model.
B. Optimization based on distance: Select this option to select design points based on the distance optimization method. The design scheme selected by this standard can evenly expand the design points in the design space. This method is used when the model needs to be selected in advance.
2. Number of points in the best design: enter the number of points selected for the best design. If the selection criterion is "D- optimality", the number of points must be at least the same as the number of items contained in the model; If the selection criterion is Distance-based Optimization, the number of points must be less than or equal to the number of design points established in the candidate settings.
3. Specific design columns: If the selection criterion is "distance-based optimization", you need to delete columns that are not included in the optimization design. By default, Minitab includes all input variables in the design.
4. Task.
A. choose the best design: choose the best design.
B. Expand/improve the design: add or improve the existing design.
C. evaluation design: evaluation design.
Zhang Chi Consulting Group believes that Six Sigma still has room for improvement if there is a shadow of the process.
In manufacturing, people always focus on optimizing product quality; In the service industry, people pay attention to customer relationship. The application of Six Sigma to enterprises can be summarized as follows: (reducing costs, improving productivity, increasing market share, retaining customers, shortening cycle time, reducing defects, changing corporate culture, improving products/services, and enhancing the comprehensive competitiveness of enterprises. )
