This directory contains the Fortran 77 codes for the open-loop and the closed-loop simulations for the Tennessee Eastman process (TEP) as well as the training and testing data files used for evaluating the data-driven methods (PCA, PLS, FDA, and CVA).

The descriptions of each file is shown below:

File name	Description
`temain.f`	open loop simulation codes for the TEP
`temain_mod.f`	closed loop simulation codes for the TEP
`teprob.f`	subprogram for the simulation codes for the TEP
`d00.dat`	training file for the normal operating conditions
`d00_te.dat`	testing file for the normal operating conditions
`d01.dat`	training file for Fault 1
`d01_te.dat`	testing file for Fault 1
`d02.dat`	training file for Fault 2
`d02_te.dat`	testing file for Fault 2
`d21.dat`	training file for Fault 21
`d21_te.dat`	testing file for Fault 21

Each training data file contains 480 rows and 52 columns and each testing data file contains 960 rows and 52 columns. An observation vector at a particular time instant is given by

 x = [XMEAS(1), XMEAS(2), ..., XMEAS(41), XMV(1), ..., XMV(11)]^T

where XMEAS(n)is the n-th measured variable and XMV(n) is the n-th manipulated variable.

Instructions for running the program

Go to line 220, change NPTS to the number of data points to simulate. For each minute of operation, 60 points are generated.
Go to line 226, change SSPTS to the number of data points to simulate in steady state operation before implementing the disturbance.
Go to line 367, implement any of the 21 programmed disturbances. For example, to implement disturbance 2, type IDV(2)=1.

The program will generate 15 output files and all data are recorded every 180 seconds, see Table 1 for details.

The default path is the home directory. To change the file name and path, modify lines 346-360 accordingly.

To overwrite the files that already existed, change STATUS='new' to STATUS='old' from lines 346-360.

Table 1: Content of the output files

#	File Name	Content
1	`TE_data_inc.dat`	Time (in seconds)
2	`TE_data_mv1.dat`	Measurements for manipulated variables 1 to 4
3	`TE_data_mv2.dat`	Measurements for manipulated variables 5 to 8
4	`TE_data_mv3.dat`	Measurements for manipulated variables 9 to 12
5	`TE_data_me01.dat`	Measurements for measurement variables 1 to 4
6	`TE_data_me02.dat`	Measurements for measurement variables 5 to 8
7	`TE_data_me03.dat`	Measurements for measurement variables 9 to 12
8	`TE_data_me04.dat`	Measurements for measurement variables 13 to 16
9	`TE_data_me05.dat`	Measurements for measurement variables 17 to 20
10	`TE_data_me06.dat`	Measurements for measurement variables 21 to 24
11	`TE_data_me07.dat`	Measurements for measurement variables 25 to 28
12	`TE_data_me08.dat`	Measurements for measurement variables 29 to 32
13	`TE_data_me09.dat`	Measurements for measurement variables 33 to 36
14	`TE_data_me10.dat`	Measurements for measurement variables 37 to 40
15	`TE_data_me11.dat`	Measurements for measurement variable 41

To ensure the randomness of the measurement noises, the random number G in the sub program (teprob.f, line 1187) has to be changed each time before running temain_mod.f.
Save the changes in temain_mod.f and teprob.f and compile the program in unix by typing
```
  f77 temain_mod.f teprob.f
```
Run the program by typing
```
  a.out
```

`teprob.f`

Subroutines

TEFUNC - Function evaluator to be called by integrator
TEINIT - Initialization
TESUBi - Utility subroutines ($i = 1, 2, ..., 8$)

The process simulation has 50 states (NN=50).

If the user wishes to integrate additional states, NN must be increased accordingly in the calling program.

The additional states should be appended to the end of the YY vector, e.g. YY(51), .... The additional derivatives should be appended to the end of the YP vector, e.g. YP(51),....

To initialize the new states and to calculate derivatives for them, we suggest creating new function evaluator and initialization routines as follows.

C-----------------------------------------------
C
      SUBROUTINE FUNC(NN,TIME,YY,YP)
C
      INTEGER NN
      DOUBLE PRECISION TIME, YY(NN), YP(NN)
C
C  Call the function evaluator for the process
C
      CALL TEFUNC(NN,TIME,YY,YP)
C
C  Calculate derivatives for additional states
C
      YP(51) = ....
      YP(52) = ....
         .
         .
         .
      YP(NN) = ....
C
      RETURN
      END
C
C-----------------------------------------------
C
      SUBROUTINE INIT(NN,TIME,YY,YP)
C
      INTEGER NN
      DOUBLE PRECISION TIME, YY(NN), YP(NN)
C
C  Call the initialization for the process
C
      CALL TEINIT(NN,TIME,YY,YP)
C
C  Initialize additional states
C
      YY(51) = ....
      YY(52) = ....
         .
         .
         .
      YY(NN) = ....
C
      RETURN
      END
C
C-----------------------------------------------

Differences between the code and its description in the paper:

Subroutine TEINIT has TIME in the argument list. TEINIT sets TIME to zero.
There are 8 utility subroutines (TESUBi) rather than 5.
Process disturbances 14 through 20 do NOT need to be used in conjunction with another disturbance as stated in the paper. All disturbances can be used alone or in any combination.
