This is a flow shop scheduling with total tardiness minimization.
Deterministic Version
The classical tardiness calculation model for flow shop scheduling

The Processing time is given and deterministic.
Use python and Gurobi to solve it.
The model is in the Research Notes Book for reference

deterministic

This is a flow shop scheduling with total tardiness minimization with two machines(deterministic) need to be re-entered.
modify the classical tardiness model:
1, transform it as a flow shop with bypass
2, add the disjunctive constraints
3, add starttime and Y_ij binary variables
