Benefi ts
Improves Product Quality
• Minute-by-minute feedback enhances operators’ decisions in real time to meet changing process
and manufacturing conditions
• Predictive measurement of key product quality characteristics reduces variability
• Soft Sensors can be easily integrated with control systems to provide tighter process performance
Reduces Production Costs
• Decreases off -spec production and raw material waste by identifying process errors before they occur
• Reduces lab sampling costs by lengthening the frequency between samples and eliminating unnecessary tests
• Simulates future outcomes and potential cost and risk of options through sophisticated “What-Ifs”capability

Overview
Leading in today’s competitive manufacturing environment requires maximizing the performance of every process throughout the plant.But you can’t control what you can’t measure and timely, accurate process measurements aren’t always available. Now there’s a cost-eff ective way to augment your laboratory analyses and instrumentation – with PlantPAx ModelBuilder. ModelBuilder enables real-time monitoring and prediction of the process characteristics critical to peak performance. The result is improved production effi ciency, reduced product variability and waste,and increased profi tability.

Soft Sensors Overview
A Soft Sensor is a model that predicts process values based on real-time process data. Soft sensors provide virtual measurements of variables that are diffi cult to measure by physical devices due to the limited reliability and associated cost. This model supplements traditional laboratory measurements by reducing the time interval needed to supply results from hours to minutes.

The Challenge
Many production processes are under-instrumented. Whether it’s due to insuffi cient lab capacity or the expense of the testing, many production processes require hours or even days to produce lab samples. During this time,the production process may have unknowingly drifted out of specifi cation.

The Solution
PlantPAx ModelBuilder creates online predictive models that augment hardware instruments and laboratory analyses to provide real-time estimates of process and product conditions. These software models, in the form of a Soft Sensor, provide the feedback and predictive process
information needed to keep production on track.

Building Soft Sensors
PlantPAx ModelBuilder can be used “off -line” to better understand process behavior. In off -line mode, you can analyze complex linear and nonlinear processes.Using the historical process data, the analysis tools can extract, clean and model historical process data to gain insight into the key process variables that most aff ect quality.

Simple and Intuitive User Interface
ModelBuilder makes model development easier through the use of point-and-click technology. This environment automates and guides the user through data extraction,modeling and scenario building, performing tasks in minutes that used to take hours or days. This environment allows a greater ease of use while incorporating best engineering practices.

Extract Data from Any Environment
ModelBuilder uses data extraction to pull data from historians and immediately make the data available for modeling into an easy, spreadsheet-like format.

Data Pre-processing tools
Data pre-processing is a critical part of creating a robust model of your process. With the pre-processing data tools you can analyze tens of millions of data points in minutes.
• Easily edit and remove data
• Combine multiple fi les for analysis
• Merge variables with diff erent dates and times
into a common dataset

Enhanced Data Visualization
ModelBuilder’s advanced data visualization features allow you to easily see patterns in your data. The tool provides an extensive set of plotting options for use in screening and analyzing data, including histograms,principle components, time series, correlation, scatter and probability. Three-dimensional plots of the modeled outputs allow users to examine the response surface,depicting the multidimensional impact of process variables.

Automated Model Building and Training
Modeling the process is performed in two steps:confi guring a model, and training the model. Users
confi gure a model by specifying which variables are inputs and which are outputs of the process, and specify time delay relationships that exist between the variables.ModelBuilder has the option to
