Design of Experiments: The Taguchi Method

ANOVA-TM® for Windows is based on the methods developed by Dr. Genichi Taguchi. This indispensable software is an orderly and methodical process for systematically assessing experimental results (when a variety of factors dynamically effect a specific quality characteristic). ANOVA-TM® employs an easy-to-use Windows graphical user interface.

ANOVA-TM will help…

• Maximize output and quality while minimizing product cost
• Reduce output variability and process sensitivity to noise factors

Features include…

• 32-bit application—compatible with MS Windows operating systems
• New configuration features: turn on or off warning messages, signal-to-noise (s/n) formulas, etc.
• Reset array option when editing an orthogonal array
• Updated dynamic characteristic calculations in accordance with ASI
• S/n data table for dynamic characteristics with new columns to represent intermediate calculations for compounded and non-compounded signal factors
• Response and s/n ratio window titles now show total mean average, total s/n average and total slope average, respectively
• New dialog for Anova table to facilitate pooling of factors
• Response graph window title includes the analysis type, useful in dual graph mode
• Two new workbook examples for dynamic characteristics from the ASI Robust Design Manual
• Individual orthogonal array files and 4-way analysis of an orthogonal array or single factor (orthogonal arrays up to L108 in size)
• Decomposition of factors to unit degree of freedom, computation of interactions between factors, and use of s/n, sensitivity analysis, and omega transformation in calculations
• Dual graphs for raw versus s/n and s/n versus sensitivity as well as user-defined s/n ratio editor
• Auto pooling on V, F, and Rho% (plus un-pooling functions)
• Display and print-level sums, level averages, and process averages
• Graphics capabilities for level average response tables (a line graph for variable data and a histogram for attribute data)
• Capability of generating data-collecting forms on which to set up experiments

ANOVA-TM® Professional

With just a mouse click or keystroke, ANOVA-TM® Professional for Windows delivers crisp, clean, full-color screens allowing users to choose and highlight precisely what they wish to view

Highlights…

• Enhanced Help menu
• Rapid navigation—select files, experiments and tables via icons, tool bar buttons and menus
• Custom screens—mix and match, overlay, tile and cascade multiple windows. Display a single experimental layout, data spreadsheet and graph
• Share data—ANOVA-TM Professional’s spreadsheets can be copied and pasted with ease

Design Array…

• Automatically selects the appropriate array, allocates factors and interactions to columns and modifies the array to allow for multi-level factors
• Creates powerful designs using intuitive layout and on-line documentation help
• Eliminates leafing through pages of linear graphs and modifying them to create the right design
• Avoids transcription errors when creating multi-level factors
• Allows user to enter the number of levels for each factor, the interactions to be studied and nominate the columns

Features include…

• Graphs for level average response tables
• Histograms for attribute data
• Decomposition of factors to unit degree of freedom
• Use of signal-to-noise sensitivity analysis and omega transformation in calculations
• Extended capabilities for dual display of raw data and signal-to-noise and sensitivity from nominal to best
• ANOVA table identifies and analyzes degrees of freedom, sum of squares, variance, percent contribution for factors and interactions or their decompositions
• Generation of optimum experimental conditions including repeating the process up to 100 interactions or until the optimum condition occurs
• Automatic filling of the orthogonal array allows users to produce designs quickly
• Optional manual filling of the orthogonal array gives users complete control over array design
• Supports interactions between factors
