summary:

Why IIoT & Big
data analytics?

They enables real-time (remote) monitoring and control,
predictive maintenance, etc. These capabilities help improve plant
efficiencies by achieving better control, reducing off spec production,
reducing equipment failures and process down time, etc.

What are our contributions?

We’ve
made contributions to all aspects of smart manufacturing. From hardware to software,
from data collection, data management, to data analytics. We
have demonstrated how to make standard unit operations smart by utilizing
noninvasive IIoT sensors, Raspberry Pi
microcontrollers, lightweight wireless communication protocols, systems engineering
enhanced machine learning algorithms, model based feature selection, data
mining etc.

Specific
contributions:

1.    
IIoT enabled industrial testbeds:

Every step involved in developing IIoT enabled testbeds
will be discussed. We have tested IIoT
temperature sensor, vibration/accelerometers sensor (both digital and analog),
near IR light sensor, IR camera, video camera etc.

Key discussion points:

-       Lab
setup, experimental design & IIoT data
characteristics & challenges.

-       Predictive modelling framework built
with brief description of data
compilation, data mining, and data analysis procedures.

-       Novel
model based data filtering or
feature selection approach capable of selecting relevant information for
vibration datasets.

-      
Performance comparison of hierarchical linear modelling with neural networks (ANN & LSTM).

2.    
Statistics
pattern analysis (SPA) modelling for spectrum data:

We will discuss SPA based modelling approach
developed for spectrum data. Developed approach captures more information with
less computation ideal for smart-manufacturing applications.

Basic
Idea:

-      
Divide
spectrum in different intervals and calculate statistics for each.

-      
Identify
most relevant statistics and use as independent variables.

Scope:

-       Tested
on 4 public real world NIR, UV/Vis spectrum data from different industries.

-       Compared
with 4 other linear, non-linear regression approaches

Major Advantages:

-              
Better prediction accuracy with improved
robustness.

-              
Simpler model with few important variables.

-              
Incorporates non-linearity.

-              
Faster training and validation.

3.    
Statistics
pattern analysis (SPA) modelling for batch data:

Next a variant of SPA modelling approach is
presented for semiconductor batch
data. Proposed variant was proven to
have better performance by comparing its performance with other approaches
used in semiconductor industry.

Proficient
