Since a state-of-the-art solver could not find a solution with a reasonable gap within an acceptable time limit, a column generation and a mixed integer programming-based heuristic are proposed. While the mixed integer programming-based heuristic outperforms the column generation heuristic in terms...
These matheuristics are based on a Mixed Integer Programming model used to find feasible solutions. We discuss the applicability and effectiveness of the matheuristics to obtain solutions to the MWTR problem. The purpose of the MWTR problem is to find a minimum weighted tree connecting a set of...

This study considers the problem of multi-product multi-level capacitated lotsizing and sequencing problem with sequence-dependent setups. A Mixed Integer Programming (MIP) formulation of the problem is proposed which is impractical to solve in reasonable computing time for non-small instances. ...
The second stage refers to the operating theatre scheduling problem with the objective of minimizing total tardiness of surgical cases and total waiting time of surgeons in operating rooms. For each problem investigated, a mathematical formulation using a mixed integer programming has been suggested. ...
In this article, we will use mixed integer (linear) programming as a showcase for our computational experiments. Mixed integer programming (MIP) is to solve the optimization problem x̃opt∈argmin{cTx∣Ax≤b,xj∈Z for all j∈J}, with A∈Rm×n,b∈Rm,c∈Rn, and J⊆{1,…,n}. ...
The algorithm works such that each service, one by one, is updated according to the solution of the above defined mixed integer problem. Then the MCFP is solved to update the total revenue, and the effect of new changes is once again estimated with the shortest path procedure. To diversify...

In a theoretically oriented work, Guignard and Ahlatcioglu present a matheuristic called the Convex Hull Heuristic (CHH) to find good feasible solutions to mixed integer programming problems with a nonlinear objective function and linear constraints. The CHH is based on the mathematical programming alg...
