The behaviors of these actions depend on the input data provide by the model user. These data will be detailed in the section “HOW TO USE IT”.

The by-products generated by the companies are differentiated into five types, which follow the following rule:

* Type of by-product generated by the company = A -> Type of by-product the company can use as raw-material = E
* Type of by-product generated by the company = B -> Type of by-product the company can use as raw-material = A
* Type of by-product generated by the company = C -> Type of by-product the company can use as raw-material = B
* Type of by-product generated by the company = D -> Type of by-product the company can use as raw-material = C
* Type of by-product generated by the company = E -> Type of by-product the company can use as raw-material = D
