Mixed Integer Program Solver¶
🚧 Under Construction 🚧 Until better docs arrive there is just some AI generated generic description of MIP
A Mixed Integer Program (MIP) solver is a type of optimization software that is used to solve complex mathematical problems. MIP solvers are particularly useful in job shop scheduling problems, which involve scheduling a set of jobs on a set of machines subject to various constraints. In a job shop scheduling problem, each job consists of a set of operations that must be performed on a set of machines in a specific order. The goal is to minimize the total time required to complete all jobs while satisfying various constraints.
MIP solvers work by formulating the job shop scheduling problem as a mathematical model that can be solved using linear programming techniques. The model consists of a set of decision variables, constraints, and an objective function. The decision variables represent the start times of each operation on each machine, and the objective function represents the total time required to complete all jobs. The constraints represent various constraints such as machine capacities, precedence constraints, and resource constraints.
In the current implementation of the job shop scheduling problem, machine capacities have been added as a constraint. This means that each machine has a limited capacity, and the total processing time of all jobs assigned to a machine cannot exceed its capacity. This constraint can be incorporated into the mathematical model by adding additional constraints that limit the total processing time of jobs assigned to each machine.
MIP solvers can be applied to solve job shop scheduling problems by formulating the problem as a mathematical model and then using the solver to find an optimal solution. The solver works by iteratively solving a series of linear programming problems, each of which is a relaxation of the original problem. The solution to each relaxation provides a lower bound on the optimal solution, and the solver uses this information to guide the search for the optimal solution.
In summary, MIP solvers are powerful optimization tools that can be used to solve complex job shop scheduling problems. The current implementation of the job shop scheduling problem extends the problem by adding machine capacities as a constraint. This constraint can be incorporated into the mathematical model used by the MIP solver to find an optimal solution. By using MIP solvers, it is possible to find optimal solutions to job shop scheduling problems that are difficult or impossible to solve using other methods.
