Dynamic Inoperability Input-Output Model

DIIM provides the Demand-Reduction and Recovery Dynamic Inoperability Input-Output Model (DIIM) for interdependent functions as described in the papers:

• Haimes, Y. Y., Horowitz, B. M., Lambert, J. H., Santos, J. R., Lian, C. & Crowther, K. G. (2005). Inoperability input-output model for interdependent infrastructure sectors. I: Theory and methodology. Journal of Infrastructure Systems, 11, 67-79.

DIIM also provides the Static Demand-Driven and Supply-Driven Inoperability Input-Output Models (IIM) for interdependent functions as described in the papers:

• OpenBLAS (Intel MKL is recommended)

Supported Compilers

Compiler	Versions Tested
GCC	10, 11
Clang	12, 13, 14
Visual Studio	VS2019, VS2022
XCode	14.2

Obtaining the Source Code

The source code can be obtained from

    git clone https://github.com/stigrs/diim.git

Building the Software

These steps assumes that the source code of this repository has been cloned into a directory called diim.

1. Create a directory to contain the build outputs:

    cd diim
    mkdir build
    cd build
   

2. Configure CMake to use the compiler of your choice (you can see a list by running cmake --help):

    cmake -G "Visual Studio 17 2022" ..
   

3. Build the software (in this case in the Release configuration):

    cmake --build . --config Release
   

4. Run the test suite:

    ctest -C Release
   

5. Install the software:

    cmake --build . --config Release --target install
   

6. If you want to install the Python wrapper, cd to the directory diim and run pip:

    pip install .
   

All tests should pass, indicating that your platform is fully supported.
